Why Nearsightedness Is Increasing in Children — And What Parents Can Do About It
Nearsightedness, also known as myopia, is becoming more common in children worldwide. A study published in the British Journal of Ophthalmology found that nearly one-third of kids globally are affected — and the numbers are rising.
Since the 1990s, myopia rates among children have steadily climbed. Following the COVID-19 pandemic, researchers observed an even sharper increase. Projections now suggest that by 2050, up to 40% of children may develop nearsightedness.
Why the Increase?
While genetics and natural eye development play a role, environmental factors are making things worse. Activities like excessive screen time, reading up close for long periods, and not spending enough time outdoors have all been linked to this surge in myopia.
“Vision issues can seriously affect a child’s learning and development — from struggling to see the board in school to difficulty reading or playing sports,” says Dr. Dalila Irons Holland, a pediatrician at Advocate Children’s Hospital. “While myopia is common, there are things parents can do to help reduce the risk.”
Dr. Irons Holland’s Top Tips for Healthy Vision
1. Schedule Regular Eye Exams
Nearsightedness can develop slowly and may not be easy to notice right away. Annual eye checkups can catch vision problems early so treatment can begin as soon as possible.
2. Limit Screen Time
Too much time on phones, tablets, or computers can strain a child’s eyes and increase the risk of myopia. Set limits on recreational screen use and encourage regular breaks.
3. Encourage Outdoor Play
Spending time outdoors has been shown to help reduce the chances of developing nearsightedness. Aim for at least one hour outside per day, especially in natural light.
Bonus Tip:
Try the 20-20-20 rule — every 20 minutes, have your child look at something at least 20 feet away for 20 seconds. This helps relieve eye strain from close-up activities.
