A REFRACTOMETER WITH A COMPARATIVE VISION CORRECTION SIMULATOR

摘要

A method and apparatus for vision testing and for simulation of eyesight correcting modalities is disclosed, the method including generating one or more images to be viewed by a patient, modulating the wavefront of each image by a differing amount and/or changing other optical attributes of one or more images by differing amounts, and selecting the preferred image based upon patient response. The apparatus includes devices for generating one or more images to be viewed by a patient, modulating the wavefront of each image by a differing amount and/or changing other optical attributes of one or more images by differing amounts, and devices for selecting the preferred image based upon patient response.
