Everyday Eye Care Tips: A Practical Checklist for Healthy Eyes

Most serious eye problems cannot be prevented by willpower alone: genetics and age play a large part. Yet a surprising amount of vision loss is linked to things we can influence, such as eye injuries, untreated infections, smoking, uncontrolled diabetes, missed check-ups and years of unprotected sun exposure. Small habits, repeated daily, add up to a real difference over a lifetime.

This guide brings the most useful, evidence-based habits together into a practical checklist. You do not need to do everything at once. Pick the areas where you have the most room for improvement, build those habits, and come back to the list from time to time.

Your everyday eye care checklist at a glance

Use this table as a quick self-check. Each area is explained in more detail below.

1. Get your eyes checked regularly

An eye examination is far more than a reading-chart test. An optometrist or ophthalmologist can measure your eye pressure, look at the optic nerve and retina, and spot early signs of conditions that cause no pain or obvious symptoms until damage is advanced. Glaucoma, diabetic retinopathy and early macular degeneration are classic examples.

• Children need vision screening at key ages, because a lazy eye responds best to treatment when caught early.
• Adults without symptoms or risk factors are generally advised to have an eye test every one to two years, depending on national guidance and age.
• People over 40 should have a baseline comprehensive examination if they have not already, as recommended by the American Academy of Ophthalmology.
• People with diabetes need regular retinal screening, usually at least once a year.
• Anyone with a family history of glaucoma or macular degeneration may need more frequent checks.

2. Protect your eyes from injury

Eye injuries are a leading cause of preventable vision loss. They happen at work, in sports and, surprisingly often, at home: during DIY, gardening, cleaning with chemicals or opening champagne bottles.

• Wear safety glasses or goggles when drilling, sawing, hammering, grinding, mowing, trimming hedges or using power tools.
• Use goggles when handling cleaning chemicals, bleach, oven cleaner or drain cleaner, and store them out of children's reach.
• Choose sports eyewear with polycarbonate lenses for racket sports, ball sports and anything with fast-moving objects.
• Keep bungee cords, fireworks and laser pointers away from faces.
• Know the first aid for a chemical splash: rinse immediately with plenty of clean water for at least 15 minutes and seek urgent care.

3. Practise good eye hygiene

Hands and rubbing

Wash your hands before touching your eyes, inserting contact lenses or applying drops. Avoid rubbing your eyes: rubbing spreads germs, worsens allergy and irritation, and frequent vigorous rubbing has been linked to keratoconus. If your eyes itch, a cool compress or lubricating drops are better options.

Eyelids

If your eyelids are often crusty, red or itchy, gentle daily lid hygiene with a warm compress and cleaning of the lash line can help. Persistent symptoms may indicate blepharitis, which benefits from a structured routine.

Make-up

• Replace mascara and liquid eyeliner about every three months.
• Never share eye make-up or apply it in a moving vehicle.
• Avoid applying eyeliner to the inner rim of the eyelid, where it can block oil glands.
• Remove all make-up before sleeping.
• Throw away eye products after an eye infection.

Contact lenses

Contact lenses are safe when used correctly, but poor hygiene is a major cause of serious corneal infections. Never sleep in lenses unless they are designed and prescribed for it, never rinse lenses or cases with tap water, avoid swimming or showering in lenses, and replace lenses and cases on schedule. Read our list of contact lens hygiene mistakes to avoid.

4. Build healthy screen habits

Long hours at screens do not cause permanent eye damage in adults, but they often cause tired, dry, burning eyes, blurred vision and headaches, known as digital eye strain. Simple habits make a big difference:

1. Follow the 20-20-20 rule: every 20 minutes, look at something about 6 metres (20 feet) away for 20 seconds.
2. Blink fully and often: we blink much less while concentrating on a screen.
3. Position your monitor about an arm's length away, with the top of the screen at or slightly below eye level.
4. Reduce glare: place screens at right angles to windows and adjust brightness to match the room.
5. Increase text size rather than leaning forward.
6. Keep your prescription up to date: even a small uncorrected error can add strain. People over 40 may benefit from dedicated computer glasses.
7. Humidify and redirect airflow: avoid air vents blowing at your face.

For children, screen time also matters because time indoors at near tasks is associated with the development of myopia, while time outdoors appears protective.

5. Respect the sun

Ultraviolet (UV) radiation contributes to cataract, pterygium, growths on the eyelids and, after intense exposure, painful sunburn of the cornea (photokeratitis, as in snow blindness). Never look directly at the sun, including during an eclipse, without certified eclipse glasses.

• Choose sunglasses labelled as blocking 100% of UVA and UVB, or marked UV400, or meeting recognised standards such as ISO 12312-1 or the CE category system.
• Darker lenses do not automatically mean better UV protection; the UV filter is what matters.
• Wraparound styles and a wide-brimmed hat reduce light coming in from the sides and above.
• Take extra care near snow, water and sand, which reflect UV, and at high altitude.
• Children's eyes transmit more UV, so sunglasses and hats are worthwhile for them too.

6. Eat for your eyes

No single food will sharpen your eyesight, but a diet rich in vegetables, fruit, fish and whole foods supports the retina and overall health. Key nutrients include:

• Lutein and zeaxanthin: found in spinach, kale, broccoli, peas and egg yolk, and concentrated in the macula.
• Omega-3 fatty acids: oily fish such as salmon, sardines and mackerel.
• Vitamin C and E, and zinc: citrus fruit, peppers, nuts, seeds, legumes and whole grains.
• Vitamin A: carrots, sweet potatoes and dark leafy greens; deficiency causes night blindness, which is rare where diets are varied.

Specific supplement formulas based on the AREDS2 trial are recommended only for people with intermediate or advanced age-related macular degeneration, not as general prevention. Talk to your eye doctor before starting supplements. Our page on nutrition for eye health explains the evidence.

7. Lifestyle habits with big effects

Do not smoke

Smoking substantially increases the risk of age-related macular degeneration and cataract and is linked to thyroid eye disease and dry eye. Stopping at any age reduces risk over time.

Stay active

Regular physical activity helps control weight, blood pressure and blood sugar, which protects the blood vessels of the retina.

Sleep well

Adequate sleep lets the eye surface recover, supports tear quality and helps prevent eyelid twitching and puffy eyes.

Manage chronic conditions

Diabetes and high blood pressure are major causes of retinal damage. Keeping blood sugar, blood pressure and cholesterol in the target ranges your doctor sets is one of the most effective ways to protect your sight.

Spend time outdoors

Outdoor time is good for general health and, for children, is one of the best-supported ways to reduce the risk of developing myopia.

8. Know your family history

Many eye conditions run in families, including glaucoma, macular degeneration, high myopia, keratoconus and some retinal dystrophies. Ask relatives about their eye conditions and tell your eye care professional, because it may change how often you need to be checked.

A note on eye exercises

Eye exercises are popular online, sometimes with exaggerated claims. The honest picture: they can relieve strain, encourage breaks and blinking, and, under professional guidance, help specific problems such as convergence insufficiency. They do not cure short-sightedness, long-sightedness, astigmatism, presbyopia, cataract or glaucoma. Treat them as a comfort tool, not a replacement for glasses or medical care.

When to see a doctor

Healthy habits reduce risk but do not replace professional care. Book an eye examination if you notice gradual changes such as blurred vision, difficulty with night driving, frequent headaches with reading or persistent eye discomfort.
