I feel the same way about my blindness. Giving sight back to those who have lost it through head injuries, diabetes and other causes would be wonderful -- especially for the elderly who happen to be the largest growing population of the visually impaired and blind. As for myself, I was born blind and wouldn't opt for this. You can't miss what you never had and I don't see (no pun intended) any reason for changing the only world I"ve ever known.
