Ray Charles Robinson

Ray Charles is one of the most popular Blues singer in history. When he was seven years old, he lost his vision but before that, he liked playing the piano. His vision issues still didn't stop him from being good at what he does. Being blind helped him a lot, his disability worked in his favor even though he was "picked on" because of it. People appreciated the fact that he had a disability and yet was good at playing the piano, he didn't let something like that get in his way and become famous. And up to this point, he's still famous and known and is a role model to a lot of people.

But my question is, did the fact that Ray Charles was blind play a role/help him become famous?

Is he famous just because he's blind? How much better was he from an average not blind piano player?
