A recent study has found that more than one in three children and teenagers worldwide suffer from myopia, or shortsightedness. This eye condition affects the ability to see objects far away clearly and is commonly corrected with glasses or contact lenses. Experts believe that excessive screen time and lack of physical activity may contribute to the increasing prevalence of myopia, especially among urban-dwelling girls.
Researchers at Sun Yat-sen University in China conducted a comprehensive analysis, projecting that the number of myopia cases could exceed 740 million by 2050. The study, published in the British Journal of Ophthalmology, highlighted a concerning trend of myopia worsening with age and starting in early childhood.
The analysis, which included data from over 5 million children and teenagers from 50 countries, noted a significant increase in myopia prevalence in recent years. Factors such as the Covid pandemic and sedentary lifestyles were suggested as reasons for this rise.
Moving forward, the researchers emphasize the importance of reducing screen time and increasing physical activity to combat the growing public health concern of myopia. While acknowledging study limitations, they stress the urgent need for preventive measures to address this global health burden.
