- Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds.
- Keep screens an arm’s length away and slightly below eye level.
- Blink consciously – screen use can cut your blink rate by half.
- Get a complete eye check-up every 1–2 years, or sooner if symptoms persist.
Most of us now spend the better part of our waking hours looking at a screen – work on a laptop, scrolling on a phone, then unwinding in front of the TV. Our eyes were not designed for hours of close, fixed focus, and they let us know through tired, dry, burning or blurry vision. Doctors call this digital eye strain or computer vision syndrome.
The good news: it is usually temporary, and a few small habits make a big difference.
- 10+ hrsaverage daily screen time for many office workers
- ~50%drop in blink rate while staring at a screen
- 20 secis all a proper eye break takes
Signs your eyes need a break
A gritty, sandy feeling as the tear film dries out.
Text goes soft after long sessions, especially in the evening.
Usually around the forehead and temples.
From leaning in towards a screen that is too far or too low.
Your daily eye-care routine
- 01Practise the 20-20-20 rule
Every 20 minutes, look at something about 20 feet (6 metres) away for at least 20 seconds. A phone reminder helps until it becomes a habit.
- 02Set up your screen correctly
Place the monitor an arm’s length away with the top of the screen at or just below eye level. Increase text size rather than leaning closer.
- 03Match brightness to the room
A screen that is much brighter or darker than its surroundings makes your eyes work harder. Avoid glare from windows behind the screen.
- 04Blink fully and often
Every so often, close your eyes gently for two seconds, then open. This spreads a fresh tear film across the eye.
- 05Keep the air kind to your eyes
Direct AC or fan airflow dries the eyes quickly. Angle vents away from your face and drink enough water through the day.
If your eyes feel dry or gritty despite regular breaks, preservative-gentle lubricating eye drops (artificial tears) can restore comfort. Ask your pharmacist or eye doctor which strength suits you.
What about blue-light glasses?
Blue-light filters and glasses are popular, but current research shows little evidence that they reduce eye strain. Screen-related discomfort comes mainly from focusing for long periods and blinking less – not from blue light itself. Using night mode in the evening may still help some people sleep better.
Children and screens
Children rarely complain of eye strain, so watch for rubbing eyes, holding devices very close or headaches after school. Encourage outdoor play every day – time in daylight is linked with a lower risk of short-sightedness (myopia) in children.
Your eyes do not need less technology – they need more breaks from it.

Nutrition for healthy eyes
Leafy greens, carrots, eggs, citrus fruits and nuts provide vitamin A, lutein, zeaxanthin, vitamin C, vitamin E and zinc – nutrients that support the retina and the lens. A colourful plate is one of the simplest things you can do for long-term eye health.
you notice sudden vision loss, flashes of light, a curtain over your vision, severe eye pain, or redness that does not settle in a day or two. These need prompt medical attention.
Frequently Asked Questions
Does screen time permanently damage the eyes?
For adults, there is no evidence that normal screen use causes permanent damage. The discomfort of digital eye strain is temporary and improves with rest, breaks and correct screen setup.
How often should I get my eyes tested?
Adults should have a complete eye examination every 1–2 years. People with diabetes, high blood pressure, glaucoma in the family, or those over 40 may need more frequent checks.
Can I use lubricating drops every day?
Most lubricating (artificial tear) drops are designed for regular use. If you need them more than 4–6 times a day, or symptoms don’t improve, consult an eye specialist.
