Something not quite right?
💛 Why this site exists
When my daughter was diagnosed with Stargardts, I had so many questions. I couldn't find anywhere that had everything in one place.
So I built it. This site is here to help anyone living with sight loss, and those closest to them.
If your condition isn't listed, and I'll look into adding it.
Free, independent, and built for people with sight loss.
Find your condition
Search 17 eye conditions — get research, practical guides, benefits help & support
Type your condition then tap Search (or press Enter)
Just diagnosed?
Start here.
You don't need to figure everything out today. Here are five things that actually matter in the first weeks.
1
Get a follow-up appointment
Ask your ophthalmologist what your diagnosis means for your vision long term. Write your questions down beforehand — you will forget them in the room.
2
Ask for a CVI
Your Certificate of Visual Impairment is free and issued by your ophthalmologist. It unlocks benefits, rehabilitation, council tax reductions, and a free bus pass.
3
Call RNIB
Call 0303 123 9999 and tell them your condition. They will tell you exactly what you are entitled to. Most people are surprised by how much support is available.
Is this for your child?
4
Don't apply for benefits alone
RNIB or Citizens Advice will help you fill in PIP or DLA forms for free. Applications made with support succeed far more often than those completed alone.
5
Search for your condition above
Use the search box above to find your condition — research, assistive technology, step-by-step guides, and support organisations, all in one place.
Take it one step at a time. You do not have to work through this alone.
📰Recent UpdatesMay 2026

Daily Life
Everyday Guide
Practical tips to make daily life easier — covering the things that matter beyond the clinic. Tap any topic to expand it.
You are not alone. Every tip here comes from the community — people with sight conditions who have found what works. If you have something to add, .
Organisation
A place for everything
Keep everything in consistent, predictable locations. Use tactile markers (rubber bands, bump dots, or textured tape) on dials, appliances, and containers. If something moves, announce it to household members.
Safety
Hob and oven safety
Induction hobs are significantly safer — the surface doesn't heat directly
Use oven gloves that extend to the elbow
Long-handled silicone tools keep hands away from heat
A talking thermometer removes guesswork on meat temperatures
Consider a slow cooker for safer, hands-off cooking
Gadgets
Helpful kitchen technology
Talking scales and measuring jugs — available from RNIB Shop and Amazon from around £15
Talking microwave — fully voiced controls, available via RNIB Shop
Liquid level indicator — clips to a cup and beeps when liquid reaches the top, around £8
Large print or braille labels — for tins, packets, and bottles
Bump dots — adhesive tactile dots to mark key settings on any dial or remote, around £6
Technique
Chopping and preparation
Use a contrasting chopping board — light board for dark foods, dark board for light. A non-slip mat under the board prevents sliding. Keep fingers in the 'claw' grip when cutting. An apple slicer or egg slicer removes the need for knife skills for many common tasks.
Support
RNIB and rehab support
A Vision Rehabilitation Specialist (VRS) can visit your home and give personalised kitchen training — completely free. Ask your ophthalmologist or local authority sensory team for a referral. rnib.org.uk ↗
Newborns
Caring for a baby
Use a consistent changing station — always in the same place, everything within reach
Wrist rattles on babies help you locate and track them by sound
Bright, contrasting clothing on young babies helps with any remaining vision
A baby monitor with a vibrating receiver means you don't need to rely on hearing or sight alone
Sling-style baby carriers keep the baby close and in contact — very effective for blind and partially sighted parents
Day to day
Routines and structure
Consistent routines are a gift to both parent and child — everyone knows what comes next. Colour-coded belongings (child's bag always this colour, coat always on this hook) create system and independence for the child too.
Schools
School and activities
Let the school know about your sight loss and ask for printed communications also by email. For trips and events, don't hesitate to ask another parent to guide you — most people are delighted to help when asked directly.
Emotional
You are a good parent
Sight loss does not determine the quality of your parenting. Research consistently shows that children of disabled parents develop exceptional empathy, independence, and resilience. RNIB has a dedicated parents' community and information at rnib.org.uk ↗. Look Up UK also provides peer support specifically for parents with sight loss.
Support
Practical help available
Local authorities can provide a carer or support worker to assist with childcare tasks if needed — request a social care assessment. This is separate from any benefits you claim. Sense ↗ and RNIB both have family support services.
Running
Guide running
Guide running (running with a sighted guide connected by a tether or holding a rope) is one of the most popular sports for people with sight loss. UK Athletics ↗ has a guide runner network. The Blind Veterans UK and British Blind Sport can also match you with a local guide runner.
Para Sport
Classified para sports
Goalball — a team sport designed specifically for people with visual impairment. All players wear blackout masks. Hugely sociable and competitive. British Blind Sport ↗
Tandem cycling — cycling on a tandem bicycle with a sighted pilot. Active communities across the UK
Blind football — 5-a-side with a ball containing a bell
Showdown — a table-top sport similar to table tennis for visually impaired players
Visually impaired skiing — guided skiing is accessible across many UK and European resorts
Gym
Using a gym with sight loss
Ask the gym for an induction specifically focused on your needs — under the Equality Act they must provide this. Request a consistent machine layout and ask staff to guide you initially. Most gym equipment is accessible by touch once you know where it is.
At home
Home exercise
Audio-described yoga and fitness classes are increasingly available. Yoga with Adriene on YouTube is highly accessible by audio alone. Many blind and partially sighted people find swimming excellent — lanes provide natural guidance and lifeguards are trained to assist.
Organisation
British Blind Sport
The national organisation for sport for people with sight loss. Find local clubs, events, and activity programmes at britishblindsport.org.uk ↗.
Getting started
Organise your products
Use tactile labelling (bump dots, rubber bands, braille labels, or different-shaped containers) to distinguish products by touch. Group products in a consistent order — left to right or by product type — and return everything to exactly the same place every time.
Foundation
Foundation and base
Tinted moisturiser or BB cream is more forgiving than foundation for blending without full sight
A beauty blender or sponge blends more evenly than a brush and is easier to control
Applying with fingertips and blending outward in consistent strokes works very well
A lighted magnifying mirror maximises any remaining vision
Eyes
Eye makeup
Pencil eyeliner is easier to control than liquid
Use your fingertip to feel the lash line, then apply liner along the upper lid only — less precision needed
A lash comb separates mascara — run it through from root to tip using touch to guide
Eyeshadow sticks are much easier than palettes and brushes — blend with fingertips
Guide dots (tiny raised stickers at the corners of the eye) can help with liner application
YouTube
Watch and learn
Several blind and partially sighted beauty YouTubers share detailed audio-described tutorials. Molly Burke and Lucy Edwards both cover makeup with low vision in accessible, practical videos worth searching for.
Grooming
Shaving and grooming
Electric shavers are significantly safer than wet razors. Consistent routines in a consistent order make grooming confident and independent. A tactile mirror (handheld with tactile border) helps orient any remaining vision.

You can book by phone or via the Passenger Assist app. Staff will meet you at the station, guide you to your platform, and ensure you board safely. Book at least 2 hours in advance where possible. nationalrail.co.uk ↗
Bus
Buses and local transport
All modern UK buses announce stops via audio — if your local bus doesn't, report it to the bus operator. Ask the driver to let you know when your stop is coming. The TfL Taxi Card (London) and local authority taxi schemes provide subsidised taxis for disabled people — check with your council.
Apps
Navigation apps
Soundscape (Microsoft) — free iOS app that uses 3D audio to describe your surroundings, landmarks, and junctions as you walk
Be My Eyes — free app connecting you to a sighted volunteer via video call for real-time visual assistance anywhere
Google Maps — turn-by-turn navigation works excellently with VoiceOver and TalkBack
Seeing AI — reads signs, menus, and text in real time using your phone camera
Training
Orientation and mobility training
Free specialist training to help you travel safely and independently is available via your local authority rehabilitation service. This includes long cane training and route learning. Ask your ophthalmologist or council sensory team for a referral. Guide Dogs UK also provides free travel training. guidedogs.org.uk ↗
Holidays
Accessible travel and holidays
Always notify airlines and hotels of your sight loss when booking — assistance is free and legally required. Disability Holidays Guide and Enabled Holidays specialise in accessible UK and international breaks. ABTA members are required to provide assistance on request.
Your rights
Equality Act 2010
Your employer is legally required to make reasonable adjustments for your sight loss. These can include screen magnification software, adjusted lighting, modified duties, remote working, or additional support. Refusing to make reasonable adjustments is unlawful disability discrimination.
Funding
Access to Work — up to £69,260/year
Access to Work is a government grant that pays for equipment and support you need to do your job that your employer cannot reasonably fund. This covers screen readers (JAWS, ZoomText), magnifiers, support workers, and taxi fares to work. Apply at gov.uk/access-to-work ↗ — before buying anything privately.
Technology
Essential workplace technology
JAWS or NVDA — screen readers that read all on-screen content aloud (Access to Work funded)
ZoomText — screen magnification with text-to-speech
Dragon NaturallySpeaking — dictation software replacing the need for typing
Large print keyboard — high contrast keys for partially sighted users
Braille display — connects to any computer for silent braille output
Support
RNIB Employment Services
RNIB's employment team provides free, confidential advice on disclosure, adjustments, redundancy, and career development. Call 0303 123 9999 or visit rnib.org.uk ↗.
Self-employment
Running your own business
Access to Work covers self-employed people too. Enterprise Nation and the Prince's Trust both support disabled entrepreneurs. Many people with sight loss find self-employment offers the flexibility and control that employment sometimes can't.
Important
You are allowed to feel however you feel
Diagnosis with a sight condition — or progressive vision loss — involves real grief. Anger, denial, sadness, and fear are all completely normal. There is no right way to feel and no timeline. Acknowledging those feelings, rather than pushing them down, is the starting point.
Free counselling
RNIB Sight Loss Counselling
RNIB provides free talking therapy sessions with counsellors who specialise in sight loss. This is different from general counselling — these therapists understand the specific emotional landscape. Call 0303 123 9999 to be referred. rnib.org.uk ↗
Crisis
If you need to talk now
Samaritans: 116 123 — free, 24 hours a day, 7 days a week. Crisis Text Line: Text SHOUT to 85258. MIND: 0300 123 3393.
Community
Peer support
Connecting with others who understand your experience is consistently described as one of the most powerful things people do after diagnosis. Every specialist charity listed on this site has peer support groups — online and in person. You do not have to work through this alone.
Carers
Support for family members and carers
Carers UK (carersuk.org) provides free support specifically for people caring for someone with a disability. Carers are entitled to their own needs assessment from the local authority. Carer's Allowance is £86.45/week (May 2026) if you provide 35+ hours of care per week.

Medical terms explained in plain English. These are the words you will hear most often at eye clinics and in research articles.
Tip: Use your browser's find function (Ctrl+F on desktop) to search for a specific term. New to eye conditions? See our
A
Acuity (Visual Acuity) — A measure of how clearly you can see detail. Expressed as a fraction, e.g. 6/6 is normal vision, 6/60 means you see at 6 metres what a normally sighted person sees at 60 metres.
AMD (Age-related Macular Degeneration) — See Macular Degeneration.
Ang-2 (Angiopoietin-2) — A protein involved in blood vessel growth. Targeted by newer treatments for wet AMD and diabetic macular oedema alongside VEGF.
AON (Antisense Oligonucleotide) — A type of therapy that uses short strands of genetic material to correct faulty gene instructions. Being investigated for conditions including Usher syndrome.
AREDS2 — A large clinical trial that identified a specific combination of vitamins and minerals (lutein, zeaxanthin, vitamins C and E, and zinc) that slows progression of intermediate AMD.
Autosomal Recessive — An inheritance pattern where a child must inherit a faulty gene from both parents to develop the condition. Neither parent may be affected themselves.
Autosomal Dominant — An inheritance pattern where inheriting just one copy of a faulty gene is enough to cause the condition.
B
Biallelic — Having mutations in both copies of a gene (one inherited from each parent). Required for eligibility for some gene therapies including Luxturna.
Braille — A tactile reading and writing system using raised dots. Refreshable braille displays connect to phones and computers to translate on-screen text into braille in real time.
C
Cones — Photoreceptor cells in the retina responsible for colour vision and fine detail in normal lighting. Concentrated in the macula. Absent or non-functional in achromatopsia.
CRISPR — A gene editing technology that can precisely cut and modify DNA. Being investigated for conditions including LCA caused by CEP290 mutations.
CVI (Cerebral Visual Impairment) — Visual impairment caused by damage to the visual processing areas of the brain rather than the eyes themselves.
CVI (Certificate of Visual Impairment) — A certificate issued by your ophthalmologist confirming your level of visual impairment. Enables registration with your local authority and unlocks benefits and support.
CGM (Continuous Glucose Monitor) — A wearable device that tracks blood sugar levels continuously. Relevant to diabetic retinopathy as good blood sugar control slows disease progression.
D
DAISY — Digital Accessible Information System. An audio format designed for people with print disabilities. RNIB Talking Books uses DAISY format.
Drusen — Small yellow deposits of protein and fat that accumulate under the retina. A hallmark of dry AMD. Large drusen indicate higher risk of progression.
E
EHC Plan (Education, Health and Care Plan) — A legally binding document issued by a local authority setting out the educational, health, and social care support a child with special needs is entitled to.
ERG (Electroretinography) — A test that measures the electrical activity of the retina in response to light. Used to diagnose and monitor conditions including RP, LCA, achromatopsia, and cone dystrophy.
F
Fluorescein Angiography — A test where dye is injected into the arm and photographs are taken as it passes through the blood vessels of the retina. Used to detect leaking or abnormal vessels in wet AMD and diabetic retinopathy.
Fovea — The tiny central area of the macula responsible for the sharpest, most detailed vision. Damaged in macular conditions. Underdeveloped (hypoplastic) in albinism.
Foveal Hypoplasia — Underdevelopment of the fovea. A defining feature of albinism and a key diagnostic marker visible on OCT scanning.
G
Gene Therapy — A treatment that delivers a corrected or replacement gene directly into cells, typically using a viral vector. Luxturna is the first approved gene therapy for an inherited retinal condition.
Geographic Atrophy — Advanced dry AMD where areas of retinal pigment epithelium have died, creating expanding blind spots. The first treatment (pegcetacoplan) was approved in 2024.
Glaucoma — A group of conditions causing progressive optic nerve damage, usually associated with raised eye pressure. The second most common cause of blindness in the UK.
H
HbA1c — A blood test measuring average blood sugar levels over approximately three months. A key indicator of diabetes control. Every 1% reduction in HbA1c reduces diabetic retinopathy progression risk by 37%.
hESC-RPE — Human embryonic stem cell-derived retinal pigment epithelium. Cells grown in a laboratory from stem cells and transplanted to replace damaged RPE in conditions like Stargardt disease and AMD.
I
IOP (Intraocular Pressure) — The pressure inside the eye. Elevated IOP is the main risk factor for glaucoma, though glaucoma can occur with normal IOP too.
Inherited Retinal Disease (IRD) — A group of genetic conditions causing progressive retinal degeneration, including RP, Stargardt disease, LCA, cone dystrophy, and others.
L
Lipofuscin — A toxic waste product that accumulates in the retinal pigment epithelium in Stargardt disease, gradually poisoning the cells. The target of visual cycle modulators such as emixustat.
Low Vision — Visual impairment that cannot be fully corrected by glasses, contact lenses, or surgery. Most people with low vision have some usable sight.
Luxturna — The brand name for voretigene neparvovec, the first gene therapy approved for an inherited retinal condition. Available on the NHS for patients with biallelic RPE65 mutations causing LCA or RP.
M
Macula — The central area of the retina responsible for sharp, detailed, and colour vision. Damaged in AMD, Stargardt disease, cone dystrophy, and diabetic macular oedema.
Macular Oedema — Swelling of the macula caused by leaking blood vessels. A complication of diabetic retinopathy and wet AMD. Treated with anti-VEGF injections.
Melanin — The pigment that gives colour to skin, hair, and eyes and helps protect against UV damage. Absent or reduced in albinism.
N
NICE — National Institute for Health and Care Excellence. The body that approves treatments for NHS use in England. A NICE approval means a treatment must be made available on the NHS.
Nystagmus — Involuntary, repetitive eye movements that reduce visual acuity. Associated with albinism, achromatopsia, LCA, and other conditions.
O
OCT (Optical Coherence Tomography) — A non-invasive scan that produces detailed cross-sectional images of the retina. The most important diagnostic and monitoring tool in modern eye care.
Ophthalmologist — A medical doctor specialising in eye conditions and surgery. Distinct from an optometrist (who performs eye tests) and an optician (who dispenses glasses).
Optogenetics — A technique that uses light-sensitive proteins to restore some light sensitivity to surviving retinal cells that have lost their natural photoreceptors.
P
Photophobia — Abnormal sensitivity to light. A prominent feature of achromatopsia, albinism, and cone dystrophy.
Photoreceptors — Light-sensitive cells in the retina. Rods detect light and dark and peripheral vision. Cones detect colour and fine detail.
PIP (Personal Independence Payment) — A UK disability benefit with two components — Daily Living and Mobility. Available to people aged 16–66 with a long-term health condition or disability.
Q
QTVI (Qualified Teacher of Visual Impairment) — A specialist teacher trained to support children with visual impairment in educational settings. Local authorities are required to provide QTVI support for children with a visual impairment.
R
Retina — The light-sensitive layer at the back of the eye that converts light into electrical signals sent to the brain via the optic nerve.
RPE (Retinal Pigment Epithelium) — A layer of cells behind the photoreceptors that supports and nourishes them. Damaged in Stargardt disease, AMD, and other macular conditions.
Rods — Photoreceptor cells responsible for vision in low light and peripheral vision. The first cells affected in retinitis pigmentosa.
S
Scotopic Vision — Vision in dim or dark conditions, primarily using rod photoreceptors. Normal in achromatopsia (which affects cones only). Impaired early in retinitis pigmentosa.
Stem Cells — Cells that can develop into many different cell types. Stem cell therapies aim to replace lost retinal cells in conditions like Stargardt disease and AMD.
Subretinal Injection — An injection delivered beneath the retina, used to administer gene therapies such as Luxturna directly to the photoreceptor cells.
T
Tonometry — Measurement of the pressure inside the eye (IOP). A standard part of glaucoma assessment. The familiar "puff of air" test at an optician is a form of tonometry.
TalkBack — Google's built-in screen reader for Android devices. Reads all on-screen content aloud.
V
VEGF (Vascular Endothelial Growth Factor) — A protein that stimulates abnormal blood vessel growth in wet AMD and diabetic retinopathy. Anti-VEGF injections (Eylea, Lucentis, Vabysmo) block this protein.
Visual Field — The full area you can see without moving your eyes, including peripheral vision. Progressively lost in glaucoma and retinitis pigmentosa.
VoiceOver — Apple's built-in screen reader for iPhone, iPad, and Mac. Reads all on-screen content aloud and supports braille displays.
VRS (Vision Rehabilitation Specialist) — A specialist who provides practical training and support to help people with sight loss live independently. Free via local authority referral.
X
X-Linked — An inheritance pattern where the gene mutation is carried on the X chromosome. X-linked conditions typically affect males more severely than females.
Be Prepared
Questions to Ask Your Doctor
Eye clinic appointments can feel overwhelming. Having questions written down beforehand means you leave with the information you actually need. These are the questions worth asking.

Understanding Your Eyes
Eye Health Basics
Before the medical terms make sense, it helps to understand how the eye works. This page explains the basics — clearly and without jargon.
👁️ How the Eye Works
The eye works like a camera. Light enters through the cornea (the clear front surface), passes through the lens, and is focused onto the retina at the back of the eye. The retina converts light into electrical signals that travel along the optic nerve to the brain, where they are interpreted as images.
The quality of what you see depends on every part of this system working correctly. Most eye conditions affect either the retina, the optic nerve, or the lens.
🔴 The Retina
The retina is a thin layer of light-sensitive tissue at the back of the eye. It contains two types of photoreceptor cells:
Rods — responsible for vision in low light and peripheral (side) vision. There are about 120 million rods in each eye. Rods are the first cells affected in retinitis pigmentosa.
Cones — responsible for colour vision and fine detail in good lighting. Concentrated in the macula. Absent or non-functional in achromatopsia. Progressively lost in cone dystrophy and Stargardt disease.
🎯 The Macula
The macula is the small central area of the retina — about 5mm across — responsible for your sharpest, most detailed vision. It is what you use for reading, recognising faces, watching television, and seeing colour. The very centre of the macula is called the fovea.
Conditions that damage the macula — AMD, Stargardt disease, cone dystrophy, diabetic macular oedema — affect central vision while usually preserving peripheral vision. This is why people with macular conditions often say they can see around something but not directly at it.
🧠 The Optic Nerve
The optic nerve carries electrical signals from the retina to the brain. It contains approximately 1.2 million nerve fibres. Glaucoma damages the optic nerve — usually through elevated eye pressure — causing gradual, irreversible loss of peripheral vision. Optic neuritis is inflammation of the optic nerve, often associated with multiple sclerosis.
💧 The Vitreous and Aqueous
The eye contains two fluids. The aqueous humour fills the front of the eye and is constantly produced and drained — imbalance in this system causes raised eye pressure (IOP) in glaucoma. The vitreous humour is the clear gel that fills the main body of the eye. As we age, the vitreous can shrink and pull away from the retina, causing floaters and flashing lights.
📊 Understanding Your Vision Test Results
Visual Acuity — measured as a fraction. 6/6 is normal. 6/60 means you see at 6 metres what someone with normal vision sees at 60 metres. The legal driving standard is 6/12. Partial sight registration is typically 6/60 or worse in the better eye.
Visual Field — the full area you can see without moving your eyes, including peripheral vision. Measured on a perimeter machine. Results shown as a map — darker areas indicate reduced sensitivity or blind spots.
IOP (Intraocular Pressure) — normal range is approximately 10–21 mmHg. Raised IOP increases glaucoma risk. Measured by a puff of air or a small probe touching the anaesthetised eye.
OCT (Optical Coherence Tomography) — a detailed cross-sectional scan of the retina showing its layers and thickness. The most important diagnostic tool in modern eye care. Non-invasive and takes about 5 minutes.
🏥 Types of Eye Specialist
Optometrist — performs eye tests, prescribes glasses and contact lenses, and screens for eye conditions. Available at high street opticians. NHS eye tests are free for many groups.
Ophthalmologist — a medical doctor specialising in eye conditions and surgery. Works in hospitals and specialist clinics. Diagnoses and treats eye disease.
Orthoptist — specialises in eye movement disorders, nystagmus, and children's vision.
Low Vision Specialist — provides magnifiers, tinted lenses, and practical strategies to maximise remaining vision. Available via NHS referral.
Vision Rehabilitation Specialist (VRS) — visits your home and provides practical training for daily living with sight loss. Free via your local authority.

Work
Employment & Sight Loss
Your rights, the support available, and how to thrive professionally with a sight condition. This page is also for employers who want to support a colleague or employee.
Key number: RNIB Employment Line — 0303 123 9999 — free, confidential advice on all employment matters.
⚖️ Your Legal Rights
The Equality Act 2010 protects you from discrimination at work because of your sight condition. Your employer must make reasonable adjustments to remove disadvantages you face because of your condition. Refusing to make reasonable adjustments is unlawful disability discrimination.
Reasonable adjustments can include: screen magnification software, adjusted lighting, modified duties, remote working, flexible hours, a dedicated support worker, or changes to your workstation.
The duty applies from the point of application — you do not have to be employed before requesting adjustments.
💷 Access to Work — Up to £69,260/year
Access to Work is a government grant that pays for equipment and support you need at work that your employer cannot reasonably fund. It is one of the most valuable and underused benefits available to people with sight loss.
Access to Work can fund:
Screen readers (JAWS, NVDA) and magnification software (ZoomText)
Braille displays and specialist keyboards
A support worker or job coach
Taxi fares to work if you cannot use public transport
Adaptations to equipment
Mental health support at work
Apply before buying anything privately. Access to Work cannot reimburse purchases made before the application. Apply at gov.uk/access-to-work ↗
Access to Work also covers self-employed people.
💻 Essential Workplace Technology
JAWS — the most widely used professional screen reader for Windows. Reads all on-screen content aloud. Around £900 but usually funded via Access to Work.
NVDA — a free, open-source screen reader for Windows. Excellent alternative to JAWS for many users.
ZoomText — screen magnification with text-to-speech. Particularly useful for partially sighted people who are not yet using a full screen reader.
Dragon NaturallySpeaking — voice dictation software replacing or reducing the need for typing.
Large print keyboard — high contrast keys significantly help partially sighted users.
OrCam MyEye — clips to glasses and reads documents, screens, and faces aloud. Useful in meetings and for reading printed materials.
Need training on workplace technology?Henshaws Knowledge Village ↗ provides free video guides on using accessibility technology — including screen readers and phone accessibility — specifically for people with sight loss.
🗣️ Telling Your Employer
You are not legally required to disclose a sight condition to your employer, but doing so enables you to request reasonable adjustments. Consider disclosing when:
Your condition is affecting your ability to do your job
You need adjustments to your workstation or equipment
You are applying for a role and need adjustments at interview
Your condition is likely to become apparent to colleagues
RNIB's Employment Line (0303 123 9999) provides free confidential advice on how to approach disclosure conversations and what to request.
📋 Redundancy and Dismissal
If you are made redundant or dismissed and believe your sight condition was a factor, this may be disability discrimination. Contact:
Employment tribunal claims must be brought within 3 months of the act complained of — act quickly.
🏢 Guidance for Employers
If you employ or manage someone with a sight condition, here is what you need to know:
You have a legal duty to make reasonable adjustments — this is not optional
Access to Work pays for most specialist equipment — the cost to you is usually minimal
Ask the person what they need — do not assume
A workplace needs assessment (available free via Access to Work) identifies specific requirements
RNIB offers free employer guidance at rnib.org.uk
Sight loss does not affect intelligence, commitment, or capability
💼 Self-Employment
Many people with sight conditions find self-employment offers flexibility and control that employment cannot always provide. Access to Work covers self-employed people. The Prince's Trust and Enterprise Nation both support disabled entrepreneurs. HMRC's Access to Work scheme can also fund a personal assistant for business tasks.
For Parents
When Your Child Has a Sight Condition
Finding out your child has a sight condition is one of the hardest things a parent can face. This page is for you — practical, honest, and written with the understanding that you are doing an extraordinary job.
You are not alone. Thousands of families in the UK are living full, rich, happy lives with a child who has a sight condition. This is the beginning of a journey, not the end of one.
💛 First — How You Are Feeling
Shock. Fear. Grief. Guilt. Anger. These are all completely normal responses to a diagnosis. You may feel all of them at once, or in waves over weeks and months. There is no right way to feel and no timeline for feeling better.
What parents consistently say, looking back, is that the fear of the diagnosis was worse than the reality of living with it. Children are extraordinarily adaptable. They do not mourn the vision they have never had — they grow up knowing their world, mastering it, and thriving in it.
Give yourself permission to feel whatever you feel. And when you are ready, the practical steps below are here.
📋 The First Steps
Get a genetic diagnosis — where relevant, knowing the specific gene mutation determines treatment eligibility. Free on the NHS — ask for a referral to a paediatric inherited retinal disease clinic.
Ask for a CVI — the Certificate of Visual Impairment is free and issued by your ophthalmologist. It unlocks local authority support, DLA, and educational provision.
Contact RNIB — call 0303 123 9999. Tell them your child's diagnosis. They have specialist advisors for families of children with sight conditions.
Request a QTVI — a Qualified Teacher of Visual Impairment is entitled to work with your child from the earliest age. Contact your local authority's sensory support service.
Apply for DLA — Disability Living Allowance for children under 16 can be worth over £600/month. RNIB can help with the form — it is complex but you are entitled to it.
Connect with other families — this is consistently described as the single most helpful thing parents do. Every specialist charity listed on this site has a family community.
🏫 Education
Your child is entitled to an Education, Health and Care (EHC) Plan — a legally binding document that sets out the specialist support your child must receive at school. This can fund a QTVI, specialist technology, braille resources, large print materials, and a teaching assistant.
Request an EHC needs assessment from your local authority as early as possible — ideally before your child starts school. The process takes up to 20 weeks.
At school, your child is entitled to:
Regular visits from a QTVI
Large print or braille materials
Preferential seating
A tablet or laptop for close-up work
Extra time in exams
Adjusted lighting where needed
A reader or scribe if required
If the school does not know about your child's condition, tell them in writing and follow up. Ask for a meeting with the SENCo (Special Educational Needs Coordinator) at the start of every school year.
💰 Financial Support
Disability Living Allowance (DLA) — for children under 16. Both Care and Mobility components may apply. Can be worth £600+ per month at higher rates. This is one of the most important financial supports available — do not delay applying.
Carer's Allowance — if you spend 35+ hours per week caring for your child, you may be entitled to £86.45/week (April 2026 rate).
Carer's Credit — protects your National Insurance record if you are not working due to caring responsibilities.
Council Tax reduction — available once your child has a CVI.
Call RNIB (0303 123 9999) for free help with all benefit applications. Do not try to navigate the forms alone — applications made with support succeed far more often.
🌱 Your Child's Future
Children with sight conditions go to university, have careers, travel independently, play sport, fall in love, and live full and extraordinary lives. The technology available today — and the gene therapies in development — make the outlook for many conditions better than it has ever been.
The most important things you can give your child are high expectations, the right practical support, and the confidence that their sight condition is part of who they are — not a limit on what they can become.
Your instinct to seek information, to advocate, and to understand — the instinct that brought you to this page — is already making a difference.

Registering as Sight Impaired (CVI walkthrough)
A Certificate of Vision Impairment (CVI) is the gateway to most UK sight-loss support. You cannot self-refer — only a consultant ophthalmologist can issue one.
Ask your eye consultant at your next hospital appointment whether your vision meets the CVI criteria. If it does, they complete the form (BP1 in Scotland, CVI in England/Wales, A655 in Northern Ireland).
Two categories:
Sight Impaired (SI / partially sighted) — visual acuity 3/60 to 6/60, or up to 6/24 with reduced field.
Severely Sight Impaired (SSI / blind) — visual acuity below 3/60, or below 6/60 with very contracted field.
The hospital sends a copy to you, your GP, and your local council Adult Social Care team.
Your council contacts you within ~28 days to add you to the Sight Impaired Register and offer a Vision Rehabilitation Assessment.
What registration unlocks (May 2026 figures)
Blind Person's Allowance: £3,250 added to your Personal Allowance (SSI only). Tell HMRC.
50% off TV Licence (SSI only) — apply via TV Licensing with your CVI.
Disabled Persons Railcard — 1/3 off rail fares for you and a companion, £20/year.
Free bus pass in England/Wales/Scotland (rules vary by council).
Council Tax reduction — many councils offer 25% off if you live alone with a disability. Ask.
Free NHS sight tests and help with glasses (NHS HC2/HC3 voucher).
Free directory enquiries — register with BT 195 service.
Access to Work grants if employed (see Employment page).
Concessionary parking (Blue Badge, automatic for SSI).
Postage concessions via Royal Mail Articles for the Blind (free large print and audio post).
Accessible Information Standard letter (NHS legal right)
Since 2016, the NHS Accessible Information Standard requires all NHS and adult social care services to ask you how you want information sent — large print, braille, email, audio, or BSL — and to record it on your patient record. Most patients don't know this. Use the form below to generate a letter to your GP and hospital.
Your letter (copy & send to GP and hospital)
PIP descriptor wording for sight loss
The Personal Independence Payment form (PIP2) is famously hard. These are example phrases written from a sight-loss perspective for the most common descriptors. Use them as a starting point — be honest about your own experience.
Activity 1 — Preparing food
"I cannot identify use-by dates, oven dials or knife blades safely. I have burned myself on the hob twice this year. I rely on my partner to chop ingredients and to check raw chicken is cooked. On bad-light days I cannot prepare a hot meal at all."
Activity 4 — Washing and bathing
"I cannot tell shampoo from conditioner without an iPhone label, and I cannot judge water temperature reliably. I have slipped in the shower because I cannot see soap on the floor."
Activity 8 — Reading and understanding signs, symbols and words
"Standard print is unreadable. I need 24pt or larger and I still cannot read it for more than 5 minutes without eye strain and headache. I cannot read price tags, medication labels, bus numbers or street signs."
Activity 11 — Planning and following journeys
"I cannot follow the route of an unfamiliar journey. I cannot read station signs, bus numbers or platform indicators. I have boarded the wrong bus and got lost. I require another person to accompany me on any unfamiliar journey because of overwhelming psychological distress and the risk of harm."
Tip: Use the phrase "reliably, safely, repeatedly and in a reasonable time" in every answer — this is the legal test the assessor must apply.

Eye Clinic Support
Find Your ECLO
An Eye Clinic Liaison Officer (ECLO) is a specialist support worker based in hospital eye clinics. They are one of the most useful — and least known — resources available to people with sight loss. Their help is free.
What does an ECLO do?
An ECLO bridges the gap between your clinical appointment and your life outside the clinic. They can:
Explain your diagnosis in plain language after your appointment
Help you understand what support and benefits you are entitled to
Refer you to rehabilitation services, social care, and local support groups
Help you fill in CVI paperwork and benefits forms
Connect you with counselling and emotional support
Advise on assistive technology and practical daily living aids
🔍 Find your ECLO
ECLOs are employed by hospital eye departments or charities such as RNIB, Macular Society, and Glaucoma UK. The best way to find yours:
Ask at your eye clinic — ask the receptionist or your ophthalmologist whether there is an ECLO at your hospital. Many clinics don't advertise them prominently.
Contact RNIB — call 0303 123 9999. RNIB funds ECLOs in many UK hospitals and can tell you whether yours has one.
Macular Society ECLO search — if you have a macular condition, the Macular Society funds dedicated ECLOs at many UK hospitals.
Not every hospital has an ECLO — particularly smaller or more rural units. If yours doesn't:
Ask your ophthalmologist to refer you to one at a larger nearby centre
Contact your local sight loss charity — many provide similar one-to-one support
RNIB's helpline (0303 123 9999) provides telephone ECLO-style support
The Macular Society's helpline (0300 3030 111) has specialist nurse advisors
👁️ What to ask your ECLO
What does my diagnosis mean in practical terms day to day?
What benefits and financial support am I entitled to?
How do I get my Certificate of Visual Impairment (CVI)?
Can you refer me to a Vision Rehabilitation Specialist?
Are there support groups for my condition in this area?
What assistive technology would help me most?
Are there any clinical trials I might be eligible for?

Hanfodion Iechyd Llygaid
Cyn i'r termau meddygol wneud synnwyr, mae'n helpu i ddeall sut mae'r llygad yn gweithio. Mae'r dudalen hon yn egluro'r pethau sylfaenol — yn glir ac heb jargon.
👁️ Sut Mae'r Llygad yn Gweithio
Mae'r llygad yn gweithio fel camera. Mae golau'n mynd i mewn drwy'r cornea (yr wyneb blaen clir), yn mynd drwy'r lens, ac yn cael ei ffocysu ar y retina yng nghefn y llygad.

Y macula yw'r ardal fach ganolog yn y retina — tua 5mm ar draws — sy'n gyfrifol am eich golwg mwyaf miniog a manwl. Dyma'r hyn a ddefnyddiwch i ddarllen, adnabod wynebau, gwylio teledu, a gweld lliw. Canol y macula yw'r fovea.
Mae cyflyrau sy'n niweidio'r macula — AMD, Clefyd Stargardt, Dystroffi Côn, Oedema Macular Diabetig — yn effeithio ar olwg canolog tra fel arfer yn cadw golwg ymylol.
🧠 Y Nerf Optig
Mae'r nerf optig yn cario signalau trydanol o'r retina i'r ymennydd. Mae'n cynnwys tua 1.2 miliwn o ffibrau nerfau. Mae Glawcoma yn niweidio'r nerf optig — fel arfer drwy bwysedd uchel yn y llygad — gan achosi colli golwg ymylol cynyddol ac anadferadwy. Mae Niwritis Optig yn lid ar y nerf optig, yn aml yn gysylltiedig â Sglerosis Ymledol.
📊 Deall Eich Canlyniadau Prawf Golwg
Craffter Gweledol — wedi'i fesur fel ffracsiwn. 6/6 yw normal. Mae 6/60 yn golygu eich bod yn gweld ar 6 metr yr hyn mae rhywun â golwg normal yn ei weld ar 60 metr. Y safon gyfreithiol ar gyfer gyrru yw 6/12.
Maes Gweledol — yr ardal lawn y gallwch ei gweld heb symud eich llygaid, gan gynnwys golwg ymylol. Wedi'i fesur ar beiriant perimedr.
IOP (Pwysedd Mewnolygol) — yr ystod normal yw tua 10–21 mmHg. Mae IOP uchel yn cynyddu risg glawcoma.
OCT (Tomograffi Cydlyniant Optegol) — sgan manwl trawstoriadol o'r retina. Yr offeryn diagnostig pwysicaf mewn gofal llygaid modern. Nid yw'n ymwthiol ac mae'n cymryd tua 5 munud.
🏥 Mathau o Arbenigwyr Llygaid
Optometrydd — yn cynnal profion llygaid, yn rhagnodi sbectol a lensys cyffwrdd, ac yn sgrinio am gyflyrau llygaid.
Offthalmolegydd — meddyg arbenigol mewn cyflyrau a llawdriniaeth y llygad. Yn gweithio mewn ysbytai.
Orthoptydd — yn arbenigo mewn anhwylderau symudiad y llygad, nystagmus, a golwg plant.
Arbenigwr Golwg Isel — yn darparu chwyddwyr, lensys lliw, a strategaethau ymarferol i fwyhau golwg sydd ar ôl. Ar gael drwy atgyfeiriad GIG.
Arbenigwr Adsefydlu Golwg — yn ymweld â'ch cartref ac yn darparu hyfforddiant ymarferol ar gyfer bywyd beunyddiol gyda cholli golwg. Am ddim drwy eich awdurdod lleol.

Pan fo gan Eich Plentyn Gyflwr Golwg
Mae darganfod bod gan eich plentyn gyflwr golwg yn un o'r pethau anoddaf y gall rhiant ei wynebu. Mae'r dudalen hon ar eich cyfer chi — ymarferol, gonest, ac wedi'i hysgrifennu gyda'r ddealltwriaeth eich bod chi'n gwneud gwaith ardderchog.
Nid ydych chi ar eich pen eich hun. Mae miloedd o deuluoedd yn y DU yn byw bywydau cyflawn a hapus gyda phlentyn sydd â chyflwr golwg. Dechrau taith yw hyn, nid diwedd un.
💛 Yn Gyntaf — Sut Rydych chi'n Teimlo
Sioc. Ofn. Galar. Euogrwydd. Dicter. Mae'r rhain i gyd yn ymatebion hollol normal i ddiagnosis. Gallwch deimlo pob un ohonynt ar yr un pryd, neu mewn tonnau dros wythnosau a misoedd.
Yr hyn y mae rhieni'n ei ddweud yn gyson, wrth edrych yn ôl, yw bod ofn y diagnosis yn waeth na'r realiti o fyw gydag ef. Mae plant yn hynod o addasadwy. Nid ydynt yn galaru dros y golwg nad oes ganddynt erioed wedi'i gael — maent yn tyfu i fyny gan wybod eu byd, ei feistroli, a ffynnu ynddo.
📋 Y Camau Cyntaf
Cael diagnosis genetig — lle bo'n berthnasol, mae gwybod am y mwtaniad penodol yn pennu cymhwysedd triniaeth. Am ddim ar y GIG.
Gofyn am TGW — mae'r Dystysgrif Nam Gweledol yn rhad ac am ddim ac yn cael ei rhoi gan eich offthalmolegydd. Mae'n datgloi cymorth awdurdod lleol, LDA, a darpariaeth addysgol.
Cysylltu ag RNIB — ffoniwch 0303 123 9999. Dywedwch wrthynt am ddiagnosis eich plentyn. Mae ganddynt gynghorwyr arbenigol ar gyfer teuluoedd plant â chyflyrau golwg.
Gofyn am ATHQN — mae Athro Cymwysedig Nam Gweledol yn gymwys i weithio gyda'ch plentyn o'r oedran cynharaf. Cysylltwch â gwasanaeth cymorth synhwyraidd eich awdurdod lleol.
Gwneud cais am LDA — mae Lwfans Byw i'r Anabl i blant o dan 16 oed yn gallu bod yn werth dros £600 y mis. Gall RNIB helpu.
Cysylltu â theuluoedd eraill — dyma'r peth mwyaf defnyddiol y mae rhieni'n ei ddisgrifio.
🏫 Addysg
Mae gan eich plentyn hawl i Gynllun Addysg, Iechyd a Gofal (AIG) — dogfen gyfreithiol rwymol sy'n nodi'r cymorth arbenigol y mae'n rhaid i'ch plentyn ei gael yn yr ysgol.
Yn yr ysgol, mae gan eich plentyn hawl i: ymweliadau rheolaidd gan ATHQN, deunyddiau print mawr neu Braille, eistedd yn ffafriol, tabled neu gyfrifiadur ar gyfer gwaith agos, amser ychwanegol mewn arholiadau, goleuadau addas, a darllenydd neu ysgrifennydd os oes angen.
💰 Cymorth Ariannol
Lwfans Byw i'r Anabl (LDA) — ar gyfer plant o dan 16 oed. Gall fod yn werth £600+ y mis ar y cyfraddau uwch. Hwn yw un o'r prif gymorthion ariannol sydd ar gael.
Lwfans Gofalwr — os ydych chi'n treulio 35+ awr yr wythnos yn gofalu am eich plentyn, efallai eich bod yn gymwys am £86.45 yr wythnos.
Ffoniwch RNIB (0303 123 9999) am help am ddim gyda phob cais budd-daliadau.
🌱 Dyfodol Eich Plentyn
Mae plant â chyflyrau golwg yn mynd i'r brifysgol, yn cael gyrfaoedd, yn teithio'n annibynnol, yn chwarae chwaraeon, yn syrthio mewn cariad, ac yn byw bywydau llawn ac anghyffredin. Mae'r dechnoleg sydd ar gael heddiw — a'r therapïau genynnau sy'n cael eu datblygu — yn gwneud y rhagolwg ar gyfer llawer o gyflyrau yn well nag y mae wedi bod erioed.
Mae croeso i chi gysylltu am unrhyw reswm — i awgrymu cyflwr i'w ychwanegu, i roi gwybod am wall, i gynnig adborth, neu i gael adolygiad clinigol o'r cynnwys.

⚖️ Eich Hawliau Cyfreithiol
Mae Deddf Cydraddoldeb 2010 yn eich diogelu rhag gwahaniaethu yn y gwaith oherwydd eich cyflwr golwg. Rhaid i'ch cyflogwr wneud addasiadau rhesymol i gael gwared ar anfanteision rydych chi'n eu hwynebu. Mae gwrthod gwneud addasiadau rhesymol yn wahaniaethu anghyfreithlon ar sail anabledd.
Gall addasiadau rhesymol gynnwys: meddalwedd chwyddo sgrin, goleuadau addas, dyletswyddau wedi'u haddasu, gweithio o bell, oriau hyblyg, gweithiwr cymorth penodol, neu newidiadau i'ch gweithle.
