Whats Marty Feldman got to do with having your eyesight restored?

Something to do with funny eyes i suppose.

I was born with strabismus and had surgery correcting the positioning of my eye back when I was 14 years old, but it was too late to gain normal vision because the brain simply cannot interpret the image. I've never had depth perception and cannot experience a 3D movie.

Still, I understand the gains made for the man with the bionic eye in just seeing light and dark. When I was 50, I had cataract surgery in both eyes (rare for someone my age). Surgery for my "blind" eye restored light and dark perception and surgery in my good eye restored me to normal vision. Until my vision was limited further, I'd never fully realized how much I needed light and dark perception in my blind eye.

Technology for artificial eyes has improved greatly, but the holy grail for restoring sight is getting the brain on board, getting our miraculous but imperfect biological computer to recognize restored sight or hearing and to intepret it correctly as with those born with normal senses.
