It amazes me when I hear any person prefer blindness to deafness. Such a person must have a terrible dread of being alone. Blindness makes one totally dependent on others, and deprives us of every satisfaction that results from light.
I don't think I avoided being type cast, because I do sometimes get similar roles. It is not a bad thing because we are strong at what we are strong at, not meaning that we cannot do other things, but sometimes somebody else might bring a little more realism than you, because that is more of who they are than who you are. I do get a chance to play other people and other types of roles.
