A device consisting of a pair of glass or plastic lenses worn in a frame in front of the eyes to help correct imperfect vision or protect the eyes from light, dust, and the like. Also called glasses, spectacles.
Eynak, probably related to âyené "mirror," âbginé "glass" (Mid.Pers. êwênag "mirror," from *âdênak, from Proto-Iranian *ādayanaka-, from prefix ā- + the root of Av. dā(y)- "to see," didāti "sees" (cf. Mod.Pers. didan "to see," Mid.Pers. ditan "to see, regard, catch sight of, contemplate, experience;" O.Pers. dī- "to see;" Skt. dhī- "to perceive, think, ponder; thought, reflection, meditation," dādhye; Gk. dedorka "have seen") + suffix -ak). Other obsolete Pers. equivalents for eyeglasses are cešm-e farangi "Frank/European eye" and âyene-ye farangi "Frank/European glass." And it seems that the oldest mention of eyeglasses in Pers. is by the poet Jâmi (1414-1492), who calls it farangi šišé "Frank/European glass." These paradigms support the relation between eynak and âyené. As for the more recent term sam'ak "hearing aid," which is invoked to relate eynak to eyn (Ar. 'ayn "eye"), it may have been coined on the model of eynak supposing that eyn means "eye."
