Awaiting your valueable feed back in this regard THANKING YOUS P BHOGALEKATRAJ, PUNE 411 046M - 0000  <response>: Yes The main cause of myopia is genetics more so when both the parents have myopia. But genes only decide the predisposing factor. Not all child Chat Doctor. Use of T.V. computers play stations. With prolonged use of these from close distance does cause you eye to stain which adds to the already genetic state. Healthy eating habits like free from refined packaged foods and more of fresh food with a lot of fruits and green vegetables will prevent the myopia. Eye exercises will definitely help.
