Yeah I do that whenever I think to.

When I lost my glasses I did lots of eye exercises regularly. I bought an eye patch and would throw a ball up in the air focusing on it. I'd also wear the eye patch over my stronger eye to work my weaker one more.

Focusing on distant objects & then closer objects helps work the eye muscles. 

 Wear your patch out and flip it back and forth. Id do it as a game to see who’s keen enough to notice lol
