瞖瞙（上於計反說文目中瞖也從目殹形聲字也經文從羽作翳非眼瞖字也下音莫字書云目不明也釋名云瞙幕也如隔障幕也文字集略從目作瞙經文從月作膜謂皮內肉外筋膜也）。

Cataract and corneal opacity (瞖瞙: the first [character] is *yi*, fanqie 於計. The Shuowen jiezi says: 'An opacity in the eye.' Derived from the eye radical 目 with 殹; it is a phono-semantic compound. In the sūtra text it is written with the feather radical 羽 as 翳, which is not the character for an eye opacity. The second [character] is pronounced *mo*. Character dictionaries say: 'Dimness of the eye.' The Shiming says: 'Opacity (瞙) means a curtain (幕), like a screening curtain.' The Wenzi jilüe writes it with the eye radical 目 as 瞙. In the sūtra text it is written with the flesh radical 月 as 膜, which refers to the fascia between skin and flesh).
