Refractometer equipped with a vision correction simulator by comparison .

摘要

Discloses a method and apparatus for simulation for vision inspection and vision correction modalities, the method includes generating one or more images observed by the patient, by different amounts and that to modulate the wave front of each image, different amounts only one or more of performing at least one of and changing the other optical attributes of the image, including selecting a preferred image based on the patient response. Device includes a device for generating one or more images observed by the patient, by different amounts and that modulates the wavefront of each image, other optical attributes of different amounts only one or more image including a device for performing at least one of the changing and the device to select a preferred image based on the patient response.
