1. An adaptive vision modification system, comprising:
- a sensor;
an adjustable contact lens including an adjustable optical element for modifying a visual input to a subject;
a processor operatively connected to the sensor and to the adjustable contact lens, the processor including a signal input for receiving from the sensor an image quality signal indicative of a quality of an image at a retina of the subject;
a pre-processor for preliminary signal processing of the image quality signal to produce a pre-processed signal;
a signal analyzer configured to analyze the pre-processed signal to generate as output at least one quality parameter characterizing a quality of the visual input at a retina of the subject;
a lens system controller configured to receive the at least one quality parameter and to generate a lens system control signal for controlling the adjustable contact lens in response to the at least one quality parameter;
wherein in one or more of the pre-processor, the signal analyzer, and the lens system controller are packaged separately from the adjustable contact lens.

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.
