The subject of whether blindness has borne a culture is a topic of debate in many blindness-related forums and meetings. The existence of a deaf culture is not in dispute. Many people are proud to be counted in that community and consider their inability to hear to be a characteristic and not a disability.
Blindness is viewed in almost the opposite light.
To admit that blindness was more than a disability, that it was a cultural characteristic of which we could be proud, would be like finally admitting that we are not the pitiful creatures that the media, and some of society, usually portray. To call us a culture would be like recognizing our uniqueness without belittling it. I posit that we are. Many of us use a form of written communication that differs from the mainstream. And, it is a form of reading and writing unique to the blind.
