Patent Images
1. A system for enhancing the vision of a subject, 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;
c) An image analyzer for determining a value of an image quality attribute of said reflected image; and
d) A lens system controller configured to adjust said adjustable lens system at intervals and responsive to said value 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.
