Not really. But, I believe sight will be restorative through technology. Blindness has too many causes. My cousin lost his sight of both eyes due to diabetes before reaching twenty. They actually removed both eyes. The blood vessels ruptured at the retina - diabetic retinopathy.
As he explained it to me it was so sever it was a nightmare having sight. It is like looking through a window that does not break but has severe fractures. Light does odd things, parts of objects or persons are distorted and fragmented, and so forth. He said it was horror all the time. I am not sure of the cause for removal - medical or the nightmarish sight.
