my dad had a stroke a couple of years back, and thank God, it wasn't too serious. the stroke damaged his retinas, and he now has "selective vision" which means when he looks at something, he can only see part of it. for example, if he's looking at a word, he can only see the last half of the word, unless he shifts his eyesight to see the rest of the word. i was wondering if anyone knows of any treatments that could help this. thanks!
