Combined vision and hearing loss didn't stop with Helen Keller.


People who are deaf-blind live and work in communities all across the country. Most are not totally blind and profoundly deaf─ rather, they have some degree of combined vision and hearing loss. The deaf-blind community includes individuals who are congenitally blind with hearing loss, congenitally deaf with vision loss and congenitally deaf-blind, as well as those who were born sighted and hearing and became deaf-blind due to aging, illness or trauma. It has been estimated that there are more than 1 million adults with combined vision and hearing loss in the United States​, and a recent study by the Community Research Institute at Molloy College​ puts the number as high as 2.4 million​. Their capabilities and preferences are as diverse as their backgrounds.
