The people who write to You about the irreversibility of Your case are not oftalmologie, so don'T listen to them. You need to understand that the irreversible in the body is only the external interference, everything else is reversible. From history we know quite a few "miraculous" healings. The body is capable of a lot. You're only 27 years old, you can not hurry with surgery — always plenty of time.
Instead, it would be possible to study literature on this subject:
\rThe Bates Method for Better Eyesight Without Glasses
— the original all nynesuschestvuyuschih techniques and exercises. Zhdanov, Norbekov and others. This is all taken from here, modified and issued as their own.
\rRelearning to See: Improve Your Eyesight Naturally!
— the book of a man who, as he claims, corrected vision method Bates. Contains some very detailed explanations of what he was talking about Bates. Contains a lot of nonsense, but more still interesting material.
And a bit of experience from the Internet:
It is important to remember and understand, the Bates method is not exercise is a "lifestyle"(how You should behave always, and not 5 minutes a day). Moreover, this method has not been invented, he just knew how healthy the eye behaves, and why it is unhealthy. I, personally, have heard from so many people, Choate all this nonsense and profanatsiya. BUT I haven't seen any good evidence against the theory of Bates, but his theory, in conjunction with everything that I have read and know about yoga and other technikach not hastable me to doubt it. As it uses the basic principles of healing any ailment, the relaxation. Moreover, I as a programmer can't take things on faith, so I vnikal in what he writes Bates and for me his theory is quite complete. Although, of course, it would be better proietti a series of experiments and obtain the same results, but I'm not an ophthalmologist.
My personal experience: I did not see better, at least significantly, not stial and see worse. And all for one simple reason — I'm not a regular and can't, force myself "to do." At that time, when I spend time training there are times of enlightenment and vision during prolonged reading that eyes are not tired.
The conclusions do You because it's Your health, but I wouldn't rush to surgery.
