Ive read good things about starting off into the direction of the sun at dusk and dawn. Also have heard anecdotes of people using this technique to improve eyesight
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.
