Abstract
A binocular vision apparatus allows a patient to view objects through the apparatus with polychromatic light and monochromatic aberration correction, such that the chromatic aberration of the eye can be combined with the monochromatic aberration correction, so as to provide a more accurate determination of vision quality. The binocular vision apparatus provides left and right viewing optics that can substantially maintain the line of sight of each eye, such that objects can be viewed in a room with 3D depth perception corresponding to the distance of the object from the patient. As both near and far objects can be viewed with binocular aberration correction, the patient can alternate binocular viewing between near and far vision with chromatic aberration so as to evaluate a proposed treatment such as a presbyopia correction.
