what is blind?

INFORMATION ABOUT BLINDNESS
The term blind does not necessarily mean complete loss of sight, but could also describe varying degrees of functional vision. Over 90% of individuals whoare blind have some remaining vision which can be used for a variety of tasks such as reading or travel. With the use of adaptive techniques, other sensoryinformation or special equipment, most persons who are blind or visually impaired can remain independent.
The incidence of blindness is increasing primarily because people are living longer. Major causes of visual impairment are macular degeneration, diabeticretinopathy, glaucoma, and, to a lesser degree, cataracts.
Extend the same courtesies and respect to persons who are blind or visually impaired that you would to anyone you meet.
