What is the main cause for child myopia?

The main cause of myopia, especially in children, is believed to be a combination of genetic predisposition and environmental factors. If parents are myopic, their children are more likely to develop myopia as well. However, environmental factors such as excessive near work (such as prolonged reading or screen time), limited outdoor activities, and inadequate lighting may also contribute to the development and progression of myopia in children. These factors can lead to the elongation of the eyeball, resulting in light focusing in front of the retina instead of directly on it, which causes blurred distance vision characteristic of myopia. https://www.basictrailers.com.au/
