Patent Images
1. A device for adaptively enhancing the vision of a subject, the device comprising:
- a) an adjustable lens system;
b) a wearable mounting for positioning said lens system with respect to an eye of the subject;
c) at least one image detector positioned in or on at least one of said wearable mounting or said adjustable lens system, said at least one image detector configured to detect at least one component of a finite fraction of at least first and second time varying images reflected from the eye of the subject, wherein said first and second time varying images are reflections of time varying visual inputs;
d) an image analyzer for determining a value of an image quality attribute of said first time varying image through comparison of said first time varying image with said second time varying image as a reference image, said image analyzer operatively coupled to said image detector; and
e) a lens system controller configured to adjust said adjustable lens system at intervals and responsive to said value of said image quality attribute, said lens system controller operatively coupled to said adjustable lens system and configured to be carried by the subject, said lens system controller being configured to receive data representative of said image quality attribute.

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.

16. A device for adaptively enhancing the vision of a subject, the device comprising:
-
a) an adjustable lens system; b) at least one image detector configured to detect at least one component of a finite fraction of a time varying image reflected from an eye of the subject, wherein the time varying image is a reflection of a time varying visual input; c) an image analyzer for determining a value of an image quality attribute of said time varying image through comparison of the time varying image with a reference image, said image analyzer operatively coupled to said image detector; and d) a lens system controller adapted to accept a magnification factor input including one of a user input or a preprogrammed value and to receive data representative of said image quality attribute, said lens system controller operatively coupled to said adjustable lens system and configured to adjust said adjustable lens system at intervals responsive to said value of said image quality attribute and said magnification factor input to control a magnification factor of said adjustable lens system. - View Dependent Claims (17, 18)

22. A device for enhancing the vision of a subject, the device comprising:
-
a) an adjustable lens system; b) at least one image detector mounted on, attached to, or formed integrally with at least a portion of said adjustable lens system and configured to produce signals indicative of at least one component of a finite fraction of at least first and second time varying images reflected from an eye of the subject, wherein said first and second time varying images are reflections of time varying visual inputs; c) an image analyzer configured to be carried by the subject, said image analyzer responsive to the signals indicative of at least one component of a finite fraction of said first time varying image reflected from an eye of the subject to determine a value of an image quality attribute of said first time varying image through comparison of said first time varying image with said second time varying image as a reference image, said image analyzer operatively coupled to said image detector; and d) a lens system controller configured to adjust said adjustable lens system at intervals responsive to said value of said image quality attribute, said lens system controller being operatively coupled to said adjustable lens system and configured to be carried by the subject. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
