It's only about $250 per eye for corrective Lasik surgery. Other than that, It's glasses or contact lenses. I have heard of certain eye exercises that can improve eye sight, but it depends on the severity of the problem. I, too, have myopic eyesight, with one eye really worse than the other. It's a misshape of the lens, being oval instead of round.
Magick just doesn't work that way. It cannot change shape of body parts, nor take away (excess weight), nor add to (wings, etc.).
