thanks gord, Aleksandr and others, that's quite helpful. I've read about similar excersises and tried some.
I'm nearsighted, I wear glasses with -2.5, but what worries me most is that my vision is slowly deteriorating..
It looks that most of these exercise systems are quite similar, however I heard various claims at how effective it can be, some say they managed to restore the vision and get rid of glasses in just a week, other boast more reasonable achievements, like being able to use weaker glasses after a couple weeks. Either way I guess it's worth a try
