Patent ID: 8244342

Claim:
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.
