I have actually heard about the fact that you can adjust your eye sight for training, I was told by a friend some years ago. However I never knew of anyone trying it. This will be interesting to follow ! My friend told me that the fact that we can improve our sight or even solve our problems with vision ourselves is a well hidden secret. The glass wear industry is huge and they don't want this information to leak. Too bad for them this post is on the decentralized block chain and they can't stop it hehehe
