1. A system for modifying the vision of a subject, comprising:
- a) an adjustable lens system adapted for modifying a visual input to a subject;
b) a sensor for detecting a neuromuscular signal from said subject;
c) a signal processor including a pre-processor configured to receive as input said neuromuscular signal and to process said neuromuscular signal by performing preliminary signal processing to produce a pre-processed signal, and a signal analyzer configured to analyze said pre-processed signal to generate as output at least one quality parameter characterizing a quality of said visual input at a retina; and
d) a lens system controller configured to receive as input said at least one quality parameter and to generate as output a closed-loop control signal for updating an adjustment of said adjustable lens system at a specified update rate in response to said at least one quality parameter based upon a predetermined relationship between the value of said at least one quality parameter and a corresponding visual input.

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 of a visual input, and the focus or quality information used as a basis for controlling an adjustable lens system or optical system.
