Abstract:
1. A method for controlling functions in a powered ophthalmic lens to be worn on the eyes of an individual, the method comprising the steps of: sampling multiple sensors incorporated into the ophthalmic lens, the sensors measuring at least physiologic change, including pupil convergence, pupil position, pupil dilation, eye lid position and eye impedance, and environmental condition, including ambient light conditions; determining the results from the multiple sensors, including making comparisons to thresholds and comparisons to predetermined patterns; aggregating the results from the multiple sensors to generate a single decision signal; and configuring an actuator based on the single decision signal to implement a change in function of or maintain a function of the powered ophthalmic lens, wherein the total time required to execute the method is equal to an individual's natural physiological response time.
