A person with visual impairment. Strictly speaking, it refers to a complete lack of light perception (total blindness), but it usually includes severe amblyopia, such as being unable to tell the number of fingers at a distance of one meter. Visual impairment can be congenital or acquired due to trauma or disease. Among diseases caused by opacity of the transparent body (cornea or lens), such as corneal ulcers and cataracts, it is possible to restore a certain degree of vision through surgery, but there are many cases where damage to the retina or optic nerve cannot be stopped from progressing to blindness. → Goze (blind female musicians) / Zatō (headmaster) / School for the blind → Related topics Braille Source : Heibonsha Encyclopedia About MyPedia Information |
視覚障害を伴った人。厳密には光覚を全く欠くもの(全盲)をいうが,普通は1mの距離で指の数を弁じえないものなど強度の弱視までを含める。先天性のものと後天的な外傷や疾病によるものがある。疾病のうち,角膜潰瘍(かいよう)や白内障のように透明体(角膜や水晶体)の混濁によるものは,手術によりある程度の視力回復が可能であるが,網膜や視神経の障害では失明への進行をとどめえないものが少なくない。→瞽女(ごぜ)/座頭/盲学校 →関連項目点字 出典 株式会社平凡社百科事典マイペディアについて 情報 |
