I found that the See Clearly Method program is the easiest to follow along with and to be consistent and persistent with the eye exercises, kind of like an exercise tape for your eyes! I highly recommend it.
The Bates method books may ultimately be telling you the same thing. In the Bates book below, he mentioned how when he put an eye chart for children to read for 5 minutes a day, none of the children needed glasses or maybe small percentage after a long time. It makes me excited that people can improve their eyesight without glasses uses various different variations of the Bates method. The important thing to do is to go through the exercises consistently and if anything for a long time, however how a life improvement without glasses an upgrade is what we should be thinking about. Good luck in your pursuits of vision improvement!
