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]

   2. (Zool.)
      (a) An American fresh-water food fish (Stizostedion
          vitreum) having large and prominent eyes; -- called
          also glasseye, pike perch, yellow pike, and
          wall-eyed perch.
      (b) A California surf fish (Holconotus argenteus).
      (c) The alewife; -- called also wall-eyed herring.
          [1913 Webster]
