Word Origin & History

glaucoma
1640s, from Gk. glaukoma "cataract, opacity of the lens" (cataracts and glaucoma not distinguished until c.1705), from -oma + glaukos, an adj. of uncertain origin, used in Homer of the sea as "gleaming, silvery" (apparently without a color connotation); used later with a sense
of "bluish-green, gray," of olive leaves and eyes. Homer's glauk-opis Athene could be a "bright-eyed" or a "gray-eyed" goddess. Gk. for "owl" was glauk- from its bright, staring eyes.
