1. A system for modifying the vision of a subject, comprising:
- a) an adjustable lens system adapted to modify a visual input to provide a modified visual input to the subject;
b) at least one sensor for detecting a neural signal from said subject;
c) a signal processor configured to receive as input said neural signal and to process said neural signal to generate as output at least one quality parameter representing a quality of said modified visual input; and
d) a lens system controller configured to receive said at least one quality parameter and to generate a lens system control signal for providing closed loop control of said adjustable lens system as a function of said at least one quality parameter.

Abstract
Methods and systems for modifying or enhancing vision are described. In exemplary embodiments, neural or neuromuscular activity is analyzed to determine a focus or other quality that is desired of a visual image, and the focus or quality information used as a basis for controlling an adjustable lens system or optical system.

65. A system for modifying the vision of a subject, comprising:
-
a) an adjustable optical system for modifying a real-time varying input image impinging on an eye of a subject; b) a detector for detecting a neural signal produced by said subject in response to said input image; c) a signal analyzer for performing an analysis of said neural signal to determine whether said input image is in focus on the light-sensitive surface of the retina; and d) an optical system controller adapted to control said adjustable optical system responsive to said analysis of said neural signal to bring said input image into focus on the light-sensitive surface of the retina. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73, 74)
