Blindness / Visual Impairment
Blindness is the condition of lacking visual perception. There are varying degrees of blindness, from having zero % of visual perception, to having a slightly higher percentage. An individual with zero % light perception is considered blind. However, an individual with a small percentage of vision may still lack vision and this cannot be significantly improved using standard visual aids. Individuals can either be born with a visual disability (congenital) or can acquire one later in life (acquired).
