i wear glasses 2.5-2.5 i fancy my self by buying the clip-on by CK :)) had it now for 6 years now, i have been sitting on it, dropping, hitting, ... still strong!! :)) been thinking of surgery now for as far as i can remember but too cautious and just taking my time :D...but i found out that you can restore your sight by exercising them on a daily basis along with a nutritious diet and you should see some results from the first exercise (personal experience) but i got lazy and wear my glasses again lol (there are plenty of youtube videos showing how. As for the operation, the younger you are the better also the blinder you are the better because it is relatively easy to correct wider focal distances that ever more smaller ones. Also I can tell you that they operate one eye at a time so if (God forbid) it goes wrong at first you can stop and apply for a role in The Pirate of the Dominicans the Aftermath
