On average, children started wearing glasses for myopia at age 11. About 5 percent had amblyopia (“lazy eye“), and about 4.5 percent had a squint. Overall, 26 percent of the twins were nearsighted, the study found.
Kids who had college-educated mothers, those who were born in summer months and those who spent more time using electronic devices had a higher likelihood of nearsightedness, the study found.
The findings were published online Nov. 6 in the British Journal of Ophthalmology.
Dr. Tien Wong, medical director of the Singapore National Eye Center, is co-author of an editorial that accompanied the study.
“Evidence supports a link between device screen time and myopia, which includes time on phones and tablets,” he said.
This is concerning in view of how many young kids have access to these devices, Wong said. Evidence shows 2-year-olds spend up to two hours a day using digital devices.
