瞖膜（上伊計反眼瞖也經從羽作翳亦通非本字也考聲云瞖蔽也盖也下音莫眼暈膜也）。

瞖膜 (The first character has the fanqie yi + ji; an ocular cataract [yī]. The sūtra uses the feather radical as 翳, which is also acceptable, though not the original character. The Kaosheng states: "Yi means obscured; covered." The second character is pronounced mo; a filmy cloud over the eye).
