Patent Images
1. A system for modifying the vision of a subject comprising:
- a first optical subsystem having a first spherical focal length, a first cylindrical focal power, and a first axis of cylindrical lens orientation;
a second optical subsystem having a second spherical focal length, a second cylindrical focal power, and a second axis of cylindrical lens orientation;
a switching mechanism configured to selectively direct a visual input to an eye of the subject through one of said first optical subsystem and said second optical subsystem;
an image detector adapted to detect an image reflected from said eye;
an image analyzer for determining the quality of said reflected image; and
a controller for controlling at least one of said first optical subsystem, said second optical subsystem, or said switching mechanism responsive to the quality of said reflected image.

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.

14. A system for modifying the vision of a subject, comprising:
-
a first optical subsystem having a first spherical focal length, a first cylindrical focal power, and a first axis of cylindrical lens orientation; a second optical subsystem having a second spherical focal length, a second cylindrical focal power, and a second axis of cylindrical lens orientation; a switching mechanism configured to selectively direct a visual input to an eye of the subject through one of said first optical subsystem and said second optical subsystem; an image detector adapted to detect an image reflected from said eye; an image analyzer for determining the Quality of said reflected image; and a controller for controlling at least one of said first optical subsystem, said second optical subsystem, or said switching mechanism responsive to the quality of said reflected image; wherein said first optical subsystem has a first adjustable transmissivity and said second optical subsystem has a second adjustable transmissivity, and wherein said switching mechanism is adapted to switch said first adjustable transmissivity to substantially full transmissivity and said second optical subsystem to substantially zero transmissivity in order to direct said visual input through said first optical subsystem, and switch said first adjustable transmissivity to substantially zero transmissivity and said second adjustable transmissivity to substantially full transmissivity in order to direct said visual input through said second optical subsystem.

15. A system for modifying the vision of a subject comprising:
-
a first optical subsystem having a first spherical focal length, a first cylindrical focal power, and a first axis of cylindrical lens orientation; a second optical subsystem having a second spherical focal length, a second cylindrical focal power, and a second axis of cylindrical lens orientation; an automatically controllable switching mechanism configured to selectively direct a visual input to an eye of the subject through one of said first optical subsystem and said second optical subsystem; an image detector adapted to detect an image reflected from said eye; an image analyzer for determining the quality of said reflected image; and a controller for controlling at least one of said first optical subsystem, said second optical subsystem, or said switching mechanism responsive to the quality of said reflected image. - View Dependent Claims (16, 17, 18, 19, 20)
