When I first noticed my vision going, my eyes tested -4 right eye & -2.5 in the left eye. Now I am -9.5 right & -7.5 left. Obviously I would have to do the eye exercises for longer. If you could have a guess, how much do you think my vision would improve, say after 6 months of eye exercises? If my vision does improve, I think I will keep the exercises going in fear of my sight going bad again. I tried other eye exercises from other website's, solarizing, looking at something close the quickly something long distant but it didn't work. Those tiny holes in the glasses seem like a good idea, I can't wait to try that.
