Screen Time and Children’s Eyes: What Every Parent Should Know

The 20-20-20 rule

Every 20 minutes, look at something 20 feet away for 20 seconds. Set it as a game, not a punishment.

Two hours outdoors

Daylight exposure is the strongest protective factor against myopia. Outdoor play before sunset counts more than any app limit.

Signs of trouble

Sitting close to the TV, squinting, headaches after school or frequent eye rubbing warrant an eye examination.

The takeaway

Children should have a full eye check before starting school and every two years afterwards.
