Probably having the screen too close to his eyes. I know one problem for me is that my screens are just past the point where I can see without glasses, but it's probably not a good idea to use glasses when the screen is only a foot and a half away so I can relate to the parent. My room/desk setup also doesn't allow for me to rearrange this to make my screens closer to not need glasses. Guess I'll see how much this affects me in a few years lol
