Patent Images
1. A method of providing adaptive vision modification, comprising the steps of:
- a) detecting a time-varying image coming from or formed by an eye of a subject;
b) determining at least one image quality attribute for at least one finite areal fraction of said detected image within at least one spectral waveband of finite width;
c) adjusting a lens system in response to the at least one value of said at least one image quality attribute; and
d) repeating steps a) through c) to provide ongoing vision modification adapted to the current state of at least one time-varying optical characteristic of the eye optics of said subject.

Abstract
Various embodiments of methods and systems for improving and enhancing vision are disclosed. Adjustable lenses or optical systems may be used to provide adaptive vision modification. In some embodiments, vision modification may be responsive to the current state of the user'"'"'s visual system. Certain embodiments provide correction of the subject'"'"'s near and far vision. Other embodiments provide enhancement of vision beyond the physiological ranges of focal length or magnification.

19. A method of providing adaptive vision modification, comprising the steps of:
-
a) detecting a time-varying image coming from or formed by an eye of a subject; b) determining at least one image quality attribute for at least one finite areal fraction of said detected image within at least one spectral waveband of finite width; and c) adjusting a lens system in response to the at least one value of said at least one image quality attribute; and d) repeating steps a) through c) to provide ongoing vision modification adapted to the current state of at least one time-varying characteristic of the eye optics of said subject; wherein determining said at least one image quality attribute comprises determining a sharpness within at least one finite areal fraction of said detected image within at least one spectral waveband of finite width;
wherein determining a sharpness of an areal fraction of said detected image within the at least one spectral waveband includes determining a spatial frequency content of said areal fraction of said image within said spectral waveband; and
wherein detecting said time-varying image includes generating a data set representative of said time-varying image. - View Dependent Claims (20, 21, 22, 23, 24)
