    摘要: An ophthalmic lens assembly comprising an electronic system with a controller configured to implement a blink detection algorithm is described herein. The electronic system can also include one or more power sources, circuitry, one or more sensors, clock generation circuitry, control algorithms, and lens driver circuitry. The algorithm can be used to sample, at a predetermined rate, light incident on an eye of an individual and at least temporarily save collected samples, determine when an eyelid is open or closed, determine a time period and pulse width of the blinks from the collected samples, calculate a number of blinks and the duration of the blinks in a given time period, and compare the number of blinks, the durations of the blinks in the given time period, and the time between blinks in the given time period to a stored set of samples to determine blinking patterns.

    摘要: The present invention relates to methods and apparatus for providing a variable optic insert into an ophthalmic lens. The variable optic insert may have surfaces within that have differing radii of curvature. A liquid crystal layer may be used to provide a variable optic function and in some embodiments, the liquid crystal layer may comprise polymer networked regions of interstitially located liquid crystal material. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control refractive characteristics.
