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.

75. A system for modifying the vision of a subject, comprising:
-
a) An adjustable optical system having a control signal input adapted to receive a control signal for controlling the adjustment of at least one focus parameter of a lens system; and
b) At least one image detector adapted to detect in real-time an image reflected from a retina of an eye of the subject and capable of generating as an output a reflected image signal containing information about the focus condition of said reflected image. - View Dependent Claims (76, 77, 78, 81, 82, 83, 84, 85, 117, 118)

99. A lens control system, comprising:
-
a) An image analyzer configured to receive at least one image signal detected from an eye of a subject and to determine from said image signal at least one image quality attribute; and
b) A lens controller configured to receive said at least one image quality attribute from said image analyzer and to receive a lens state signal from an adjustable lens system, and responsive to said lens state signal and said image quality attribute to generate a lens control signal for adjusting the state of said adjustable lens system to modify said at least one image quality attribute of said image detected from said eye. - View Dependent Claims (100, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 128, 129)
