It highlights that myopia has reached epidemic proportions, particularly in East Asia, with almost 90% of 18-year-olds in some urban areas being myopic. The article suggests that the significant increase in myopia is likely due to a combination of genetic and environmental factors, such as increased indoor activities and reduced time spent outdoors. It outlines various theories on the possible mechanisms behind the link between outdoor exposure and reduced risk of myopia development. The article also touches upon the potential consequences of this myopia epidemic, including higher risks of other eye diseases.
