The myopia pandemic is a global phenomenon, with an estimated 1.4 billion people worldwide suffering from nearsightedness or myopia. This number is predicted to reach 5 billion by 2050. Myopia is most common in countries with high educational attainment and urban environments, but it is increasing at an alarming rate even in rural areas. The main cause of this increase is thought to be the increased use of digital devices and lack of time spent outdoors. Recent studies have shown that spending time outdoors offers protection against myopia, as exposure to natural light helps regulate eye growth. As such, prevention strategies should include measures to encourage greater outdoor activity.Disclaimer: This summary might be generated by an AI.
