Sounds like you need someone who is closer to this situation...
I am legally blind. Not fully blind mind you. I can not drive, see any color and I am extreamly light sensitive. Now my vision is not correctable. No surgery nor any breaks throughs have come along for me quite yet. I have been through many camps and rehab schools during my life with others whom are blind or legally blind.
In my experienced opinion those who have been blind since birth or a very young age adapt the easiest. But the parents play a huge role in that. Please please if you ever have a child with an eye problem try and not shelter them. They need to know that they can do just about everything a sighted kid can do. I've seen sheltered kids who are blind and it's not healthy at all.
I don't agree that there is a high suicide rate with those whom have restored sight. The highest rate is with those who lost their sight from accidents.
With the many persons I've seen go through surgery to repair their sight, all but one had no change what so ever. The one that did is my best friend. She was fully blind in one eye and now she can see shadows and differences in light and dark areas.
This happends alot. Either nothing happens or theres a slight change.
But that hardly discourages many. As for me I'd be up for it, if anything were to come along for me. I quite enjoy my uh... more intune sense of touch and hearing. But I wouldn't be able to pass it up.
And if nothing ever comes along i'll be perfectly happy too. Theres alot of things I miss and that I'm glad I miss. Manly how rude people can be. Evil looks and gestures, I'd rather be oblivious than waste any kind of emotion in reaction to rude people.
(BTW sorry for any grammer or spelling mess ups, I know here in the GDF you guys can be sticklers lol)
P.s Please don't take your sight for granted. Or the ability to drive.
