There are several programs available to improve your eyesight with exercises and relaxation. Most of these are similar to each other. Here is a website that lists a few of them. I love sunning and palming. These exercises work well for maintaining your eyesight if you do them when your eyes start to feel strained. Do be careful to not sun in midday light or with glasses or contacts.
I had heard about the idea of being able to improve eyesight naturally, but did not take the idea seriously until I saw information like this. Once I saw the muscles involved it was easier for me to see how exercises and relaxation could help improve eyesight.
My in-laws took me to an eye doctor that does vision therapy and works to improve eyesight. I was skeptical about it, and after a bit went back to “normal” doctors. I was only seeing him once a year which was really not enough if I wanted much improvement, and I did not believe that improvement was possible. By chance I came across a book at the library several years later that had exercises and explained how improvement was possible. That find started my search into eyesight.
