I have to try this. I did some eye exercises about 3-4 years back called Trataka. No scientific evidence of it's benefits whatsoever but I had nothing to lose. A few minutes of gazing a candle in a dark room. I have worn glasses from age 10 and the only time my eye power went down was when I was doing this Trataka. Now I have terrible eyesight, long sightedness + presbyopia, can't read without glasses. May be there is something to these unscientifically proven methods. It is a pain to find a totally pitch dark room in modern cities. Light creeps in from everywhere.
