Wall-eye \Wall"-eye`\, n. [See {Wall-eyed}.]
[1913 Webster]
1. An eye in which the iris is of a very light gray or
whitish color; -- said usually of horses. --Booth.
[1913 Webster]
Note: Jonson has defined wall-eye to be "a disease in the
crystalline humor of the eye; glaucoma." But glaucoma
is not a disease of the crystalline humor, nor is
wall-eye a disease at all, but merely a natural
blemish. --Tully. In the north of England, as Brockett
states, persons are said to be wall-eyed when the white
of the eye is very large and distorted, or on one side.
[1913 Webster]

(b) A California surf fish ({Holconotus argenteus}).
(c) The alewife; -- called also {wall-eyed herring}.
