Eyes and screens: protecting children and adults

Long hours on phones, computers and tablets can cause dry, tired eyes, headaches and blurred vision. In children, too much close-up screen time and too little time outdoors are linked to short-sightedness.

Follow the 20-20-20 rule: every 20 minutes, look at something about 20 feet (6 metres) away for at least 20 seconds. Blink often, keep the screen at arm's length, a little below eye level, and reduce glare. Use lubricating drops only if a doctor suggests them.

Encourage children to play outdoors every day, because time in daylight helps protect their eyesight. Set limits on recreational screen time and keep screens out of bedrooms at night.

Take your child for an eye check if they squint, hold things close, rub their eyes often, complain of headaches, or sit very close to the board. Adults should have regular eye tests, especially if they have diabetes or a family history of glaucoma.
