Factors influencing interocular blur suppression

Abstract

An important feature of monovision correction is the ability of the binocular system to suppress blur from the defocused eye (interocular blur suppression). We conducted a study with three subjects and found that interocular blur suppression improved with higher levels of monocular defocus (addition powers in monovision) but was not

affected by the eye defocused (sighting dominant or non-dominant) or by pupil size. The selection and management of monovision patients may be assisted by an understanding of the underlying suppression processes.
