I had never heard before that playing video games may help with lazy eye. If it's true, then that's great. I wore a corrective patch when I was young but it was not fun because everyone made fun of me in school. If we had video games back then, I would have preferred to play video games.
I guess the key part is playing video games for the right amount of time. Because I know that playing video games or watching TV excessively actually makes vision first. So a doctor should be advised before using video games for lazy eye.
