What you'll learn

Regular eye exams

Comprehensive eye exams can detect conditions such as glaucoma long before you notice any change in your vision. How often you need one depends on your age and risk factors.

Screens and digital eye strain

Long hours on screens can cause tired, dry or irritated eyes. Try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.

Protecting your eyes from UV

Sunglasses that block 100% of UVA and UVB rays help protect your eyes from sun damage linked to cataracts and other conditions.

Nutrition for eye health

Leafy greens, colourful vegetables, fish and nuts provide nutrients associated with healthy eyes, including lutein, zeaxanthin and omega-3 fats.

Common vision conditions

We explain nearsightedness, cataracts, glaucoma and age-related macular degeneration — how they develop and how they are usually managed.

Warning signs to act on

Sudden vision loss, a curtain-like shadow, new flashes of light or a sudden shower of floaters need urgent medical attention.
