wall-eyed

a. [ Icel. valdeygðr, or vagleygr; fr. vagl a beam, a beam in the eye (akin to Sw. vagel a roost, a perch, a sty in the eye) + eygr having eyes (from auga eye). See Eye. ] Having an eye of a very light gray or whitish color. Booth. [ 1913 Webster ]

☞ Shakespeare, in using wall-eyed as a term of reproach (as “wall-eyed rage, ” a “wall-eyed wretch”), alludes probably to the idea of unnatural or distorted vision. See the Note under Wall-eye. It is an eye which is utterly and incurably perverted, an eye that knows no pity. [ 1913 Webster ]
