The term “deaf-blindness” may seem as if a person cannot hear or see at all. The term actually describes a person who has little or no useful sight, and little or no useful hearing. The amount of loss in either vision or hearing will vary from person to person.
Our nation’s special education law, the IDEA, defines “deaf-blindness” as:
“…concomitant [simultaneous] hearing and visual impairments, the combination of which causes such severe communication and other developmental and educational needs that they cannot be accommodated in special education programs solely for children with deafness or children with blindness. [§300.8(c)(2)]”
The National Consortium on Deaf-Blindness observes that the “key feature of deaf-blindness is that the combination of losses limits access to auditory and visual information.”  This can severely limit an individual’s natural opportunities to learn and communicate with others.
