Vision and ageing, what to screen for and when to act.
Cataracts, macular degeneration and glaucoma are the three big age-related eye conditions. Early screening keeps you driving, reading and independent for longer.

Key facts
Vision and ageing at a glance.
The three big age-related eye conditions, the screening cadence that matters, and when to escalate.
-
Presbyopia
Universal after 40 — the near-vision decline that makes reading glasses inevitable for almost everyone.
-
Cataracts
Very common after 60 — and curable with day-case surgery that has excellent outcomes.
-
AMD
Age-related macular degeneration is the leading cause of severe sight loss in over-50s in the UK.
-
Glaucoma
Silent until late — vision lost cannot be recovered, so routine screening is what protects sight.
-
Diabetes and the retina
Diabetes changes the retina — an annual diabetic eye screen is essential.
-
Screening cadence
Two-yearly eye tests from age 60 (yearly if diabetic or otherwise higher-risk).
Why this guide matters
Sight loss is often preventable.
Vision advice online is noisy. The three points below shape everything else on this page.
-
Screening from 60 changes outcomes
A two-yearly optometry review catches cataract, AMD and glaucoma early — when treatment is most effective.
-
Glaucoma is silent until late
You can lose significant peripheral vision before you notice — screening is the only reliable safety net.
-
Sudden change is an emergency
Sudden vision loss, curtains, distortion or a shower of new floaters need same-day assessment.
The evidence
A screening plan that actually preserves sight.
A pragmatic order to work through — the biggest habits first, treatment when needed.

Cataract surgery and glaucoma therapy
- 01
Anchors
Book a two-yearly eye test
From age 60 — yearly if diabetic. This one habit catches the big three (cataract, AMD, glaucoma) early.
- 02
Anchors
Ask for OCT and visual fields
Include OCT (optical coherence tomography) and visual-field testing at your review where available — both add early detection.
- 03
Anchors
Screen for AMD with an Amsler grid
A weekly 30-second check for distortion (wavy lines, missing patches) at home — cheap and effective.
- 04
Habits
Address the risk factors
Blood pressure, smoking cessation, and a Mediterranean-style diet all reduce AMD and vascular retinal risk.
- 05
Habits
Sunglasses for UV protection
Sustained UV exposure contributes to cataract and possibly AMD — sunglasses with UV400 are cheap insurance.
- 06
Treat
Manage cataracts with timely surgery
When cataract starts affecting driving, reading or work, surgery is safe and effective — don’t wait indefinitely.
- 07
Treat
Treat glaucoma promptly
Once diagnosed, drops or laser lower pressure and preserve remaining vision — adherence is everything.
Typical cadence: two-yearly review from 60 — yearly if diabetic or higher-risk.
Signs it affects you
What ageing eyes usually feel like.
A quick self-check across the common patterns. Any of these is a reason to book an eye test — a red flag means don’t wait.
-
Reading difficulty (presbyopia)
Holding text further away in your 40s — universal, easily corrected with reading glasses.
-
Cataract cloudiness
Colours look faded, headlights glare at night, vision hazes over months to years.
-
Central distortion (AMD)
Straight lines look wavy, a blurred or missing patch in central vision — see an optometrist urgently.
-
Peripheral vision loss (glaucoma)
Often silent until late — bumping into things, missing side traffic. Screening is what catches it.
-
Diabetic retinopathy
Diabetes changes the retinal blood vessels — annual retinal photography is essential.
-
Dry eye
Gritty, tired, watery eyes — very common with age and screen use, and treatable.
-
Flashes and floaters
New flashes or a sudden shower of floaters can signal retinal detachment — same-day assessment.
-
Red flag: sudden vision loss or curtains
Sudden loss of vision, or a curtain across the visual field — same-day A&E or 999.
How to do it
Practical steps that preserve sight.
Eight actions, in rough order — start with the screening cadence, then work through treatment options as they become relevant.
-
Two-yearly optometry review
The single most important habit. From age 60, every two years — yearly if diabetic or higher-risk.
-
Referral to ophthalmology for red flags
Sudden vision change, distortion, new flashes or floaters, or a painful red eye — don’t wait.
-
Cataract surgery
Day-case, safe and effective. Restores clear vision when cataract starts affecting daily life.
-
AMD — lifestyle and injections
Smoking cessation, Mediterranean-style diet, and anti-VEGF injections for wet AMD — early treatment matters.
-
Glaucoma drops or laser
Lowering intraocular pressure preserves remaining vision. Adherence to daily drops is critical.
-
Diabetic retinopathy pathway
Annual retinal photography, tight glucose and blood-pressure control, and treatment when indicated.
-
Dry-eye treatment
Lubricating drops, lid hygiene, screen breaks (20-20-20 rule) and treatment of any underlying cause.
-
Vision aids and blue-light management
Good task lighting, magnifiers, and sensible screen habits — including reduced evening screen time.

A quiet reminder
This guide is for information, not medical advice.
If you notice sudden vision change, distortion, new flashes or floaters, please seek same-day care — don’t wait for a routine appointment.

Red flags
When it is not just ageing.
These signs need urgent same-day assessment — A&E or eye casualty, not a routine appointment.
-
Sudden vision loss
Any sudden loss of vision in one or both eyes — same-day A&E or 999. Do not wait for an optometry appointment.
-
Sudden new floaters or flashes
A shower of new floaters or flashing lights can signal retinal tear or detachment — urgent same-day assessment.
-
Sudden distortion (AMD)
Straight lines suddenly look wavy or a central patch is blurred — urgent optometrist or eye-casualty referral.
-
Painful red eye with vision drop
Could be acute glaucoma, uveitis or infection — same-day assessment.
-
Peripheral vision loss
Progressive loss of side vision can be silent glaucoma — book an urgent eye test.
-
Halo around lights
Especially with pain or nausea — may indicate raised intraocular pressure. Urgent assessment.
-
Diabetes with visual change
Any new visual symptom in a diabetic patient warrants prompt review — don’t skip annual screening.
-
Head injury with visual change
Blurred vision, double vision or floaters after a head injury — urgent medical review.
-
Giant cell arteritis suspected
New temporal headache, scalp tenderness or jaw pain over 50, with any visual change — same-day medical review to prevent blindness.
Making it stick
A steady rhythm, for decades.
Four principles to keep vision protected as the years add up.
A quiet reminder
Screening quietly saves sight.
A routine appointment every two years is the single habit that catches the big three early — while there is still something to preserve.
- 01 Timing
Screening starts at 60 (earlier if diabetic)
Two-yearly eye tests from age 60 — yearly if diabetic or otherwise higher-risk. This is the single habit that catches the big three early.
- 02 Silent risk
Glaucoma won’t tell you it’s there
You can lose significant peripheral vision before you notice a thing. Regular screening is the only reliable safety net.
- 03 Lifestyle
Small habits matter for AMD
Stop smoking, keep blood pressure controlled, eat a Mediterranean-style diet, wear UV-blocking sunglasses. All small, all cumulative.
- 04 Adherence
Drops only work if you take them
Glaucoma therapy fails on adherence, not on the drops themselves. Build a daily routine and keep to it.
Frequently asked
Everything we get asked about vision and ageing.
Quick answers on eye tests, the difference between cataract, AMD and glaucoma, cataract surgery, prevention and when to seek same-day care.
-
When should I start having regular eye tests?
Two-yearly eye tests are recommended from age 60, and yearly if you have diabetes or are otherwise higher-risk. Earlier and more frequent testing is sensible if you have symptoms, a family history of glaucoma or AMD, or other risk factors.
-
What is the difference between cataract, AMD and glaucoma?
Cataract is clouding of the lens (curable with day-case surgery). Age-related macular degeneration (AMD) damages the central retina and is the leading cause of severe sight loss in over-50s. Glaucoma damages the optic nerve, is usually silent, and needs early screening to preserve vision.
-
Is cataract surgery safe?
Yes — it is one of the most commonly performed operations in the UK, done as a day case under local anaesthetic. Serious complications are rare and outcomes are excellent. Timing is when cataract starts affecting driving, reading or daily life.
-
Can I prevent AMD?
You can reduce risk substantially — stop smoking, keep blood pressure controlled, eat a Mediterranean-style diet, and wear UV-blocking sunglasses. If wet AMD develops, anti-VEGF injections can preserve or improve vision when started early.
-
Why is glaucoma called the silent thief of sight?
Because you can lose significant peripheral vision before you notice a thing. Vision already lost cannot be recovered, so routine screening is what protects sight. Once diagnosed, drops or laser lower pressure and preserve what remains.
-
When should I seek same-day care?
Sudden loss of vision, a curtain across the visual field, sudden new floaters or flashes, sudden distortion of straight lines, or a painful red eye with vision drop — same-day A&E or eye casualty. Don’t wait for an optometry appointment.
