Yes, I've heard that for some the sensory overload is too much to handle. Don't know if this is true but I heard that a man in England actually committed suicide because he just couldn't adapt; seems to me a blindfold would have been a better solution, but whatever. I guess one thing to consider too is that for a person whose sight was restored by surgery, it would be impossible to convey to sighted people exactly how they were perceiveing things, and for all anybody would know, things could be severely distorted and never look at all like they would to normally functioning eyes. I guess for that matter, normally seeing people probably perceive colors and what not differently from one another, just assuming that everybody sees a given color the same. This really hit home when I started losing my hearing and it became distorted. Much of the beauty and the richness disappeared and if I held the phone for example to my bad ear, the pitch of the dial tone was entirely different, on a different key than it was if I listen with my good ear. If my hearing had always been like that, I would have assumed that everybody heard in the same way which of course isn't the case. Beauty really is in the ears of the beholder as well. Pam .
