Funny Turtlepower, at the school for the blind I attended it was the other way around. if you had any usable vision you were made to feel guilty for having it, for example if you were playing a game with a totally blind person, often the staff would give the total person some really amazingly unfair advantage, for example I once remember myself and one other eight year old playing football against four ten year old boys and it was held to be fair because we could see, never mind the fact we were smaller and ran less far, and the blasted ball with the bell wasn't at all visible anyway .
This was definitely an attitude fostered by teachers, for example if I said "I watched a tv program" I was instantly corrected to "you mean you listened to it" and talking about colours or anything else was actively discouraged, heck they even missed the "he gave us eyes to see them" verse of the old hymn all things bright and beautiful.
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
