  • Use of an optical system simulating behavior of human eye to generate retinal images and an image quality metric to evaluate same
    Patent number: 9001316
    Abstract: A method of predicting clinical performance of an ophthalmic optical correction using simulation by imaging a series of objects of different sizes by each of a plurality of eye optical systems, each of the eye optical systems including the ophthalmic optical correction, the method providing an output value representing the resolution and contrast performance of the optical design at that vergence for the eye optical systems.
    Type: Grant
