Abstract

PURPOSE:

To analyze the influence of higher-order aberrations on binocular visual performance under mesopic conditions.

METHODS:

We measured aberrations in both eyes of 35 emmetropic observers with a Wasca aberrometer. Binocular visual performance was checked with both binocular summation for contrast sensitivity function and a parameter that characterizes stereopsis (maximum disparity).

RESULTS:

Binocular summation and maximum disparity significantly decrease with increasing interocular differences in higher-order aberrations (total, coma, and spherical aberration).

CONCLUSIONS:

At least some aspects of binocular visual performance are less effective for large interocular differences in higher-order eye aberrations.
