Here is a news article about the blind weightlifter Malek Chamoun and his ambitions.
I another article he talks about his blindness. Starting with the age of 7 his sight got worse and at the age of 12 he was legally blind. He still is able to see however: "If there are several red plates they blend into each other. I can see a blur of a bar.
The weights are easier to see than the bar. But I know the bar is going to be in the middle of the platform."
I think that is very impressive to be that good at weightlifting without being able to see - as the most learn weightlifting with their eyes.
