EFFECT OF INDUCED ANISOMETROPIA ON DEPTH PERCEPTION*

ABSTRACT Depth perception of 25 male college subjects was measured with the Howard‐Dolman Apparatus and with various lenses from ±2.00 D placed over one eye to induce anisometropia. Results showed that depth perceptual measures are very reliable (r = +0.96) and that the average depth perceptual error is affected by both plus‐ as well as minus‐lens induced anisometropia in the form of a V‐shape curve, which is minimal at the vertex where there is zero lens addition over best visual acuity corrections, proportionally increases with both plus‐ and minuslens induced anisometropia, and gradually levels off beyond the ±1.00 D levels.
