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.

117. A method of controlling a lens system, comprising:
-
receiving an image signal representing a time-varying image detected from an eye of a subject; determining at least one image quality metric of said time-varying image from said image signal within at least one spectral waveband of finite width; generating a lens system control signal based upon said at least one image quality metric; sending said lens system control signal to an adjustable lens system to cause adjustment of said adjustable lens system in an adjustment direction determined to modify said at least one image quality metric toward a target image quality metric value; and repeating said receiving, determining, generating and sending to provide ongoing vision modification. - View Dependent Claims (118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 149)

144. A system for modifying the vision of a subject, comprising:
-
an adjustable optical system adapted to modify a time-varying input image impinging on the retina of an eye of the subject; an image detector adapted to detect a time-varying image reflected from the retina; an image analyzer operatively coupled to said image detector and for determining the quality of said reflected image through comparison of a determined characteristic of said reflected image with an expected characteristic of said reflected image; and a controller operably coupled to said adjustable optical system and configured to provide ongoing control of said adjustable optical system by adjusting said adjustable optical system at intervals responsive to said quality of said reflected image. - View Dependent Claims (145, 146, 147, 148, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159)

160. A system for providing adaptive vision modification, comprising:
-
an image detector for detecting a time-varying image reflected from at least a portion of a retina of an eye of a subject; an image analyzer operatively coupled to said image detector and configured to determine the quality of said detected image through comparison of a characteristic of said time-varying image with an expected characteristic of said time-varying image; an image modulator for modulating a time-varying input image impinging on at least a portion of said retina; and a modulation controller configured to receive data representative of said quality of said detected image from said image analyzer and operatively coupled to said image modulator to provide ongoing control of said image modulator in response to said quality of said detected image. - View Dependent Claims (161, 162, 163, 164, 165, 166, 167, 168, 169, 170)
