Deafblindness
Deafblindness is the condition of little or no useful hearing and little or no useful sight. There are different degrees of vision loss and auditory loss within each individual, thus making the deafblind community unique with many types of deafblindness involved. Because of this diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual-modality deprivation in order to improve their ability to live independently. In 1994, it was estimated that roughly 35,000–40,000 United States residents are medically deafblind. Helen Keller was a well-known example of a deafblind individual.
