National Eye Health Week: 9 Smart Ways to Protect Sight

National Eye Health Week is a reminder that good vision deserves attention before something feels wrong.

Many eye conditions can develop quietly. Glaucoma, diabetic eye disease, and age related macular degeneration may cause little or no warning early on, which is one reason routine eye examinations matter.

National Eye Health Week is a UK awareness campaign led by Eye Health UK under the Vision Matters banner. In 2026, the campaign took place from September 21 to 27 and focused on routine sight tests, children’s vision, dry eyes, healthy habits, lens care, and ageing eyes.

The message should last longer than one week. Protecting your eyesight is a year round habit.

National Eye Health Week: Quick Answer

National Eye Health Week is a UK campaign designed to raise awareness of eye health and encourage people to have regular sight tests.

In 2026, it ran from September 21 to September 27.

The campaign highlighted:

• Routine sight tests
• Children’s eye health
• Dry eye
• Healthy lifestyle habits
• Everyday eye care
• Lens technology
• Ageing eyes

The most useful message is simple: you do not have to wait until your eyesight becomes obviously worse before getting your eyes checked.

Why National Eye Health Week Matters

Vision problems are common, but many people delay routine eye care because they think clear vision means healthy eyes.

That is not always true.

Some eye diseases can develop without obvious early symptoms.

Glaucoma is a good example. It often develops slowly, and many people do not notice changes until significant damage has already occurred.

A comprehensive eye examination can also detect changes linked with diabetes, high blood pressure, cataracts, refractive errors, macular degeneration, and other conditions.

9 Smart Ways to Protect Your Vision

1. Book Regular Eye Tests

Routine eye tests are one of the most practical ways to protect your sight.

An eye care professional can check:

• Visual acuity
• Prescription changes
• Eye pressure
• Peripheral vision when appropriate
• The retina
• The optic nerve
• Other signs of eye disease

The official National Eye Health Week campaign advises routine sight tests around every two years in the UK unless an optometrist recommends a different schedule.

Some people need more frequent care.

This may include people with:

• Diabetes
• High blood pressure
• Glaucoma risk
• A family history of eye disease
• Existing eye conditions
• Previous eye surgery
• Sudden vision changes

2. Know Your Personal Eye Risk

Eye care should not be identical for everyone.

Your risk can change with:

• Age
• Family history
• Diabetes
• High blood pressure
• Smoking
• Previous eye injury
• Severe short sightedness
• Medication use
• Previous eye surgery

Tell your eye care professional about your medical history, medicines, family history, and any recent changes in vision.

3. Manage Diabetes, Blood Pressure, and Cholesterol

Eye health is closely connected with the health of your blood vessels.

Diabetes can damage the small blood vessels in the retina and lead to diabetic retinopathy.

Good management of blood sugar, blood pressure, and cholesterol can help reduce the risk of diabetes related eye damage.

People with diabetes usually need regular dilated eye examinations as advised by their healthcare team.

4. Protect Your Eyes From UV Light

Ultraviolet radiation can damage the eyes over time.

Choose sunglasses that block 99 to 100 percent of UVA and UVB radiation.

A wide brimmed hat can add more protection outdoors.

Do not assume that very dark lenses provide better UV protection. The UV rating matters more than the colour of the lens.

Never look directly at the sun.

Ordinary sunglasses are also not safe equipment for directly viewing a solar eclipse.

5. Do Not Smoke

Smoking affects more than the lungs.

It is linked with a greater risk of cataracts, age related macular degeneration, and optic nerve damage.

If you smoke, quitting is one of the strongest health changes you can make for your eyes as well as your heart, lungs, and blood vessels.

6. Eat for Overall Eye Health

No single food protects eyesight by itself.

A balanced eating pattern can support the tissues and blood vessels your eyes depend on.

Useful foods include:

• Leafy green vegetables
• Colourful vegetables
• Whole fruit
• Fish
• Eggs
• Nuts
• Seeds
• Beans
• Lentils

These foods can provide nutrients such as lutein, zeaxanthin, vitamin A, vitamin C, vitamin E, zinc, and omega 3 fats.

Food cannot correct short sightedness or replace eye treatment.

7. Make Screen Use More Comfortable

Long periods of screen use can contribute to digital eye strain and dry eye symptoms.

Common symptoms include:

• Sore eyes
• Dryness
• Burning
• Blurred vision
• Headache
• Difficulty focusing

Screen use does not usually cause permanent blindness by itself, but prolonged close work can make the eyes uncomfortable.

Useful habits include:

• Taking regular breaks
• Blinking often
• Adjusting screen brightness
• Reducing glare
• Using a comfortable viewing distance
• Getting the correct glasses prescription

For children and teenagers, time outdoors is also important because outdoor activity is associated with a lower risk of developing myopia.

8. Protect Your Eyes From Injury

Many eye injuries can be prevented.

Use appropriate protective eyewear when:

• Using power tools
• Working with chemicals
• Doing home repairs
• Gardening
• Playing certain sports
• Working in environments with flying particles

If a chemical enters the eye, start rinsing immediately with plenty of clean water and seek urgent medical care.

Do not try to remove an object that has pierced the eye.

9. Use Contact Lenses Safely

Contact lenses sit directly on the eye, so hygiene matters.

Reduce infection risk by:

• Washing and drying your hands before touching lenses
• Following the recommended replacement schedule
• Using approved lens solution
• Keeping the lens case clean
• Not sharing lenses
• Avoiding sleeping in lenses unless they are specifically prescribed for overnight use
• Removing lenses if the eye becomes painful or very red

A painful red eye in a contact lens wearer needs prompt assessment because some corneal infections can threaten vision.

Common Eye Conditions Worth Knowing

Glaucoma

Glaucoma damages the optic nerve.

The common chronic forms may cause no obvious symptoms at first.

Vision loss can develop slowly, which is why routine eye tests are important.

A sudden painful red eye with blurred vision, halos, headache, nausea, or vomiting can be a different and urgent type of glaucoma and needs emergency assessment.

Cataracts

A cataract is clouding of the natural lens inside the eye.

Possible symptoms include:

• Cloudy vision
• Glare
• Halos around lights
• Reduced night vision
• Colours looking less bright

Age is a major risk factor, but diabetes, smoking, and long term UV exposure can also contribute.

Cataract surgery can restore useful vision for many people when cataracts become significant.

Age Related Macular Degeneration

Age related macular degeneration, or AMD, affects the macula, which provides detailed central vision.

It can make reading and recognizing faces difficult while peripheral vision may remain.

Risk rises with age.

Smoking is an important modifiable risk factor.

Some people with intermediate AMD may benefit from a specific AREDS2 supplement formula if an eye care professional recommends it.

AREDS2 is not a general eye vitamin for everyone.

Diabetic Retinopathy

Diabetic retinopathy happens when diabetes damages retinal blood vessels.

It may not cause symptoms early.

That is why regular retinal or dilated eye examinations are important for people with diabetes.

Managing blood sugar, blood pressure, and cholesterol can help protect vision.

Dry Eye

Dry eyes can cause:

• Burning
• Grittiness
• Redness
• Watering
• Blurred vision that comes and goes
• Eye fatigue

Dry eye can be linked with ageing, menopause, screen use, contact lenses, medicines, eyelid problems, and other conditions.

Persistent symptoms deserve proper assessment rather than relying indefinitely on random eye drops.

When Vision Changes Need Urgent Care

Routine eye tests are important, but some symptoms should not wait.

Seek urgent eye care if you develop:

• Sudden loss of vision
• A sudden increase in floaters
• New flashes of light
• A dark curtain or shadow across vision
• Sudden blurred vision
• Sudden double vision
• Severe eye pain
• A very red painful eye
• Strong light sensitivity with eye pain
• A penetrating eye injury
• A chemical eye injury

A sudden curtain or shadow, flashes, and new floaters can be warning signs of a retinal tear or retinal detachment.

Retinal detachment needs rapid assessment because treatment can help prevent permanent loss of vision.

Eye Health for Children

Children may not realize that their vision is blurred because they have nothing to compare it with.

Possible clues include:

• Sitting very close to screens
• Squinting
• Covering one eye
• Frequent headaches
• Difficulty reading
• Eye turning in or out
• Struggling at school

Vision problems can affect learning and development.

Children can have their vision assessed even before they can read letters.

Eye Health in Working Adults

Working adults often spend long hours using computers and phones.

Comfort matters, but screen breaks are not a replacement for proper eye examinations.

If text becomes harder to read, headaches are frequent, or focus feels difficult, check whether your prescription needs updating.

Adults with diabetes, high blood pressure, a family history of glaucoma, or other eye risks may need closer follow up.

Eye Health After 50 and 60

Age related changes become more common later in life.

These can include:

• Presbyopia
• Cataracts
• Glaucoma
• AMD
• Dry eye
• Diabetic eye disease

Do not assume that major sight loss is simply a normal part of getting older.

Many eye diseases can be treated or managed, especially when found early.

For more detail, read our Senior Eye Care Health Guide.

Can Eye Tests Detect Other Health Problems?

Sometimes.

Changes visible during an eye examination may suggest:

• Diabetes
• High blood pressure
• Blood vessel disease
• Some neurological conditions

An eye examination does not replace general medical care, but it can sometimes provide useful clues about broader health.

Do Eye Vitamins Prevent Vision Loss?

Not for everyone.

This is an area where marketing can become misleading.

A general multivitamin is not proven to prevent all common eye diseases.

The AREDS2 formula can help reduce progression in selected people with intermediate or advanced AMD in certain situations.

It is not recommended simply because someone wants stronger eyesight.

Ask an eye care professional before taking high dose eye supplements.

Are Carrots Enough for Healthy Eyes?

No.

Carrots provide beta carotene, which the body can convert into vitamin A.

Vitamin A is essential for normal vision, but eating extra carrots will not correct short sightedness, glaucoma, cataracts, or macular degeneration.

A varied diet is more useful than relying on one food.

Does Drinking Water Cure Dry Eyes?

No.

Good hydration supports general health, but dry eye has many possible causes.

Drinking more water does not automatically correct tear gland problems, eyelid disease, medication effects, hormonal changes, or contact lens related dryness.

Do Blue Light Glasses Protect the Eyes?

Blue light glasses are widely marketed for screen use.

They may make some people more comfortable, but they are not a proven way to prevent serious eye disease from ordinary computer screens.

Screen comfort is more likely to improve with:

• Regular breaks
• Correct prescription lenses
• Reduced glare
• Comfortable lighting
• Frequent blinking
• Managing dry eye when present

National Eye Health Week 2026 Themes

The 2026 campaign highlighted several areas of eye care.

A Simple 7 Day Eye Health Reset

Day 1: Check Your Last Eye Test

If you cannot remember when it was, that is a useful sign to check whether you are due.

Day 2: Check Your Sunglasses

Make sure they provide proper UVA and UVB protection.

Day 3: Improve Your Screen Setup

Reduce glare, adjust brightness, and take regular distance breaks.

Day 4: Review Your Health Conditions

If you have diabetes or high blood pressure, make sure eye care is included in your routine health plan.

Day 5: Add Eye Supporting Foods

Add leafy greens, colourful vegetables, fish, eggs, nuts, seeds, beans, or fruit to your meals.

Day 6: Check Contact Lens Habits

Replace old cases, review your lens schedule, and stop sleeping in lenses unless specifically prescribed.

Day 7: Learn the Emergency Signs

Remember sudden vision loss, flashes, a shower of new floaters, a dark curtain, or severe eye pain.

Conclusion

National Eye Health Week is a useful reminder that vision care should not begin only after eyesight becomes poor.

Regular eye tests, diabetes and blood pressure management, UV protection, not smoking, safe contact lens use, injury prevention, comfortable screen habits, and good nutrition all play a part in protecting your eyes.

Most importantly, learn the difference between a routine problem and an eye emergency.

Your next step is simple: check when you last had an eye examination and book one if you are overdue. Then make one eye healthy habit part of your normal routine rather than waiting for next year's National Eye Health Week.

Frequently Asked Questions

What is National Eye Health Week?

National Eye Health Week is a UK awareness campaign that promotes good eye health, regular sight tests, early detection of eye disease, and practical habits that help protect vision.

When was National Eye Health Week 2026?

National Eye Health Week 2026 took place from Monday, September 21 to Sunday, September 27.

How often should I have an eye test?

The National Eye Health Week campaign recommends routine sight tests around every two years in the UK unless your optometrist advises otherwise. People with diabetes, high blood pressure, glaucoma risk, or other eye conditions may need more frequent examinations.

Can an eye test find disease before symptoms start?

Yes. Some eye diseases, including glaucoma and diabetic eye disease, can develop without obvious early symptoms. Eye examinations can help identify problems before major vision loss occurs.

What are the most important habits for healthy eyes?

Useful habits include regular eye tests, UV protection, not smoking, controlling diabetes and blood pressure, using protective eyewear, eating a balanced diet, caring for contact lenses properly, and acting quickly when vision suddenly changes.

Does screen time damage eyesight permanently?

Ordinary screen use is more commonly linked with temporary eye strain, dryness, blurred vision, and headaches than permanent vision loss. Regular breaks, correct glasses, blinking, good lighting, and appropriate screen distance can improve comfort.

What eye symptoms are an emergency?

Sudden vision loss, severe eye pain, new flashes, a sudden shower of floaters, a dark curtain or shadow across vision, penetrating injury, and chemical eye exposure all need urgent assessment.

Does diabetes affect eyesight?

Yes. Diabetes can damage retinal blood vessels and cause diabetic retinopathy. Good blood sugar, blood pressure, and cholesterol management plus regular eye examinations can help protect vision.

Do eye vitamins protect everyone from vision loss?

No. General eye supplements are not proven to prevent all eye disease. The AREDS2 formula is useful only for selected people with certain stages of age related macular degeneration and should be discussed with an eye care professional.

Can cataracts be prevented?

Cataracts cannot always be prevented because ageing is a major factor. Avoiding smoking, protecting the eyes from UV radiation, and managing diabetes can help reduce some risk factors.

Why are regular eye tests important if I can see clearly?

Clear vision does not guarantee healthy eyes. Some conditions can develop silently, so eye examinations can detect problems that may not yet affect everyday vision.
