My brother damaged his eyesight by playing computer games from morning till night. He asked mum to buy a pair of computer glasses for him. My dad gave him a beat. From then on, he was not allowed to touch computers. We often take him to play in the outside. And ask him to do some eye exercise at the same time. Now his eyesight is much better.
