Abstract
Traditionally., large amounts of anisometropia are considered an obstacle for normal binocular vision, and clinicians strive to equate the visual acuity in the two eyes with optimal refractive correction. Anisometropia could depress binocular measures of visual acuity if the blurred image of the ametropic eye reduced the contrast of the eye with less ametropia. Anisometropic blur also produces a marked elevation of the stereoscopic depth threshold, which is considerably greater than the threshold elevation produced by equal blurring of the two ocular images (Lit, 1968; Peters, 1969; Ong and Burley., 1972; Levy and Glick, 1974; Goodwin and Romano, 1985; Lovasik and Szymkiw, 1985; Schor and Heckmann, 1989). Finally., anisometropia presents an ambiguous stimulus to accommodation whenever the test target is proximal to the unequal far points of the two eyes.
