How are dr. v in " others to see" and the author of "a ball to roll around" similar?

 Dr. V in "Helping Other to See" and the author of "A Ball to Roll Around" is similar in a way that both are trying to move past the problems of blindness. Dr. V. who is blind and the author both are a great inspiration to other people. It help builds self-confidence in spite of the disability they have. 

I hope this helps.
