Abstract
An eye model system for remotely predicting the in-vivo performance of a vision altering optic includes a representative cornea, a dispersion medium, and a retinal surface. The corneal surfaces provide anatomical shape, optical power, and higher order aberration content. The dispersion medium mimics chromatic dispersion in an actual eye. The retinal surface is moveable to provide selected defocus. A humidity and temperature enclosure may be provided. Model eye elements can be tilted or decentered to simulate actual conditions. An associated method for remotely measuring the performance of a vision altering optic to predict its performance in-vivo includes making topography, wavefront, interferometry, PSF, MTF, or other optical and/or physical measurements of the model eye system with and without the optic in combination.
