"When the researchers delved deeper they found the risk of myopia rose steeply as daily screen time increased, with 5% greater odds of myopia for one hour a day of exposure compared with no screen use, and 97% higher odds for four hours' use a day."
"Prof Chris Hammond of King's College London, a consultant ophthalmologist who was not involved in the work, said that based on a prevalence of myopia of about 15% in children aged 12 to 13 in the UK, the research suggested a child's risk of being shortsighted rose to 18% if they used a screen for an hour, and 27% after four hours."
A recent analysis of 45 studies involving over 335,000 participants indicates that each additional hour of screen time correlates with a 21% increased likelihood of developing myopia in children and adolescents. With predictions suggesting that 40% of the global youth population could be myopic by 2050, experts advocate for reduced screen time and more outdoor activities. The researchers found a steep increase in risk as daily screen exposure rises, with a staggering 97% increased risk for four hours of screen time daily, highlighting the importance of managing device usage in young populations.
