One in three kids are losing their sight; Here’s what scientists blame and how you can fix it

A recent study has revealed that one in three children worldwide is now suffering from short-sightedness, or myopia, with the rate surging significantly since the COVID-19 pandemic. According to a report by the BBC, the rise in myopia is largely attributed to increased screen time and reduced outdoor activities during lockdowns.

The study, published in the British Journal of Ophthalmology, indicates that myopia has become a major global health concern, with millions more children expected to be affected by 2050. The pandemic's impact on daily routines, especially the time spent indoors, has accelerated the issue, reported BBC.

The study's data, gathered from over five million children and teenagers across 50 countries on six continents, showed that Asia has the highest rates of myopia. In Japan, 85% of children are affected, while in South Korea, the figure stands at 73%. Countries like China and Russia also reported over 40% of children suffering from the condition. On the other hand, Paraguay and Uganda had the lowest rates, at just one per cent, while the UK, Ireland, and the US reported approximately 15%.


Between 1990 and 2023, global rates of myopia tripled, now affecting 36% of children, with a notable spike after the pandemic lockdowns. According to the researchers, myopia typically develops in primary school and worsens until the eye stops growing around age 20.

While genetics play a role, environmental factors—particularly in East Asia—also significantly increase the risk of myopia. In places like Singapore and Hong Kong, children tend to spend more time focusing on screens and books, straining their eyes and contributing to the development of the condition.

The researchers highlighted that lockdowns were a critical factor in worsening eyesight. "Emerging evidence suggests a potential link between the pandemic and accelerated vision deterioration among young adults," the study noted, as per BBC.

Projections suggest that by 2050, more than half of the world's teenagers could be affected by myopia. The study also found that girls and young women might be more vulnerable, as they tend to spend less time outdoors during their school years.

To counter the rising rates of myopia, the researchers recommend that children spend at least two hours outdoors daily, especially between the ages of seven and nine, to help maintain better eye health.
