Top ten tips for healthy eyes

Most sight-threatening eye conditions develop slowly, and many people do not notice symptoms until damage has already occurred. The good news is that a few simple habits can dramatically reduce your risk of common problems such as cataracts, macular degeneration, glaucoma and diabetic eye disease. Here are my top ten tips for keeping your eyes healthy.

1. Have regular eye examinations

Many serious eye conditions, including glaucoma and diabetic retinopathy, cause no symptoms in their early stages. A comprehensive eye examination with an optometrist or ophthalmologist can detect problems before they affect your vision. Adults should have a check every two years, or more often if you have risk factors such as diabetes, a family history of eye disease, or are over 60.

2. Know your family history

Glaucoma, macular degeneration and retinal detachment all have a hereditary component. If a close relative has been diagnosed with one of these conditions, tell your eye care professional. You may need earlier or more frequent screening.

3. Protect your eyes from UV light

Ultraviolet light from the sun contributes to cataracts and may affect the macula. Wear sunglasses that block 100% of UVA and UVB rays whenever you are outside on bright days, even in winter. Wraparound styles offer the best protection, and a wide-brimmed hat adds extra shade.

4. Stop smoking

Smoking is one of the strongest modifiable risk factors for macular degeneration and cataracts. It also damages the blood vessels that supply the retina and optic nerve. Quitting smoking reduces your risk and slows progression if you already have early signs of disease.

5. Eat a balanced, eye-healthy diet

A diet rich in leafy green vegetables, colourful fruit, oily fish, nuts and eggs provides the antioxidants, omega-3 fatty acids and vitamins that support retinal health. Lutein and zeaxanthin, found in spinach, kale and peas, are particularly important for the macula.

6. Manage screen time and take breaks

Prolonged screen use can cause dry eye, eye strain, headaches and blurred vision. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Make sure your screen is at arm's length, slightly below eye level, and well positioned to avoid glare.

7. Keep your eyes hydrated

Dry eye is increasingly common, especially with age, contact lens wear, air conditioning and screen use. Use preservative-free artificial tears if needed, blink consciously when working at screens, and consider a humidifier in dry environments. If symptoms persist, ask about meibomian gland dysfunction or blepharitis.

8. Control systemic health conditions

Diabetes and high blood pressure can both damage the eyes. Keeping blood sugar, blood pressure and cholesterol within target ranges protects the tiny blood vessels in the retina and reduces the risk of vision loss. If you have diabetes, attend your retinal screening appointments.

9. Use eye protection for risky activities

Many eye injuries happen at home or during sport. Wear safety goggles for DIY, gardening, chemical handling and any activity involving flying debris. Sports such as squash, badminton and cycling can also put the eyes at risk, so use appropriate protective eyewear.

10. Do not ignore changes in vision

Flashes of light, new floaters, a curtain across part of your vision, sudden blurred vision, or persistent eye pain all need urgent assessment. Prompt treatment can save sight in conditions such as retinal detachment, acute glaucoma and eye infections.

The bottom line

Healthy eyes are not just about avoiding problems — they are about preserving the vision you rely on for everyday life. Regular checks, sun protection, a good diet, sensible screen habits and managing your general health are the foundations of long-term eye care. If you have any concerns, book a professional eye examination rather than waiting for symptoms to worsen.
