Myopia: The Alarming Rise of Short-Sightedness in Children

Myopia: An Increasing Global Health Concern Among Children

A recent global analysis indicates a steady decline in children's eyesight, with one in three children now suffering from short-sightedness or myopia. The study suggests that the COVID-19 lockdowns have adversely affected children's vision due to increased screen time and reduced outdoor activities.

Prevalence and Predictions

The research warns of myopia becoming a significant global health concern, potentially affecting millions more children by 2050. Asia reports the highest rates of myopia among children, with Japan leading at 85% and South Korea closely following at 73%. Data shows that over 40% of children in China and Russia are afflicted. In contrast, Paraguay and Uganda report some of the lowest levels of myopia at about 1%.

Rising Rates Post-COVID

The study, published in the British Journal of Ophthalmology, analyzed data from over five million children and teenagers across 50 countries. The prevalence of short-sightedness tripled between 1990 and 2023, rising to 36%. Notably, factors like geography, genetics, and early education play crucial roles in myopia's development.

Strategies for Mitigating Myopia

Experts recommend that children spend at least two hours outdoors daily to reduce the risk of myopia. Despite the unclear reasons behind this advice, it may relate to natural sunlight exposure or focusing on distant objects. Daniel Hardiman-McCartney from the UK College of Optometrists emphasizes the importance of outdoor activities and advises parents to have their children’s eyes tested between ages seven and ten.
