Deafblindness

Deafblindness is the condition of having little or no useful sight and hearing. As with the word "Deaf", it can be capitalized to indicate that it is a culture; some prefer the spelling "DeafBlind". Deafblind people have an experience quite distinct from people who are only deaf or blind and not both. The best-known deafblind person is the author, activist and lecturer Helen Keller.
