Deficiência visual resulta quando uma condição ocular afeta o sistema visual e uma ou mais de suas funções. Tipicamente, pesquisas de base populacional medem deficiência visual usando exclusivamente a acuidade visual, com gravidade caracterizada entre deficiência visual para longe leve, moderada ou grave ou cegueira e deficiência visual para perto. Entretanto, na prática clínica, outras funções também são avaliadas, como o campo visual da pessoa, sensibilidade ao contraste e visão de cores. | |||

A vision impairment results when an eye condition affects the visual system and one or more of its vision functions. Typically, population-based surveys measure visual impairment using exclusively visual acuity, with severity categorized as mild, moderate or severe distance vision impairment or blindness, and near vision impairment. However, in the clinical setting, other visual functions are also often assessed, such as a person’s field of vision, contrast sensitivity and colour vision. | |||
