c.1200, from Old English ege (Mercian), eage (West Saxon), from Proto-Germanic *augon (cf. Old Saxon aga, Old Frisian age, Old Norse auga, Swedish öga, Danish øie, Middle Dutch oghe, Dutch oog, Old High German ouga, German Auge, Gothic augo "eye"), from PIE *okw- "to see" (cf. Sanskrit akshi "the eye, the number two," Greek opsis "a sight," Old Church Slavonic oko, Lithuanian akis, Latin oculus, Greek okkos, Tocharian ak, ek, Armenian akn).
Until late 14c. the plural was in -an, hence modern dialectal plural een, ene. The eye of a needle was in Old English; to see eye to eye is from Isa. lii:8. Eye contact attested by 1965. Eye-opener "anything that informs and enlightens" is from 1863. Have an eye on "keep under supervision" is attested from early 15c.

(Heb. 'ain, meaning "flowing"), applied (1) to a fountain, frequently; (2) to colour (Num. 11:7; R.V., "appearance," marg. "eye"); (3) the face (Ex. 10:5, 15; Num. 22:5, 11), in Num. 14:14, "face to face" (R.V. marg., "eye to eye"). "Between the eyes", i.e., the forehead (Ex. 13:9, 16). The expression (Prov. 23:31), "when it giveth his colour in the cup," is literally, "when it giveth out [or showeth] its eye." The beads or bubbles of wine are thus spoken of. "To set the eyes" on any one is to view him with favour (Gen. 44:21; Job 24:23; Jer. 39:12). This word is used figuratively in the expressions an "evil eye" (Matt. 20:15), a "bountiful eye" (Prov. 22:9), "haughty eyes" (6:17 marg.), "wanton eyes" (Isa. 3:16), "eyes full of adultery" (2 Pet. 2:14), "the lust of the eyes" (1 John 2:16). Christians are warned against "eye-service" (Eph. 6:6; Col. 3:22). Men were sometimes punished by having their eyes put out (1 Sam. 11:2; Samson, Judg. 16:21; Zedekiah, 2 Kings 25:7). The custom of painting the eyes is alluded to in 2 Kings 9:30, R.V.; Jer. 4:30; Ezek. 23:40, a custom which still prevails extensively among Eastern women.
