摘要： The present invention discloses an ophthalmic device with a retinal vascularization monitoring system and associated methods. In some embodiments, the ophthalmic device can be a contact lens with a retinal vascularization monitoring system that can be used to monitor temporal changes of a pulsating vessel forming part of the retinal vascularization. Further, the retinal vascularization monitoring system may include elements for delivering a signal, including an audible and/or visual message, to the user that can be useful for identifying abnormal conditions such as a cardiac failure without delay. The audible and/or visual messages can be signals communicated to the user using one or both of the ophthalmic device and a wireless device in communication with the ophthalmic device.

摘要： This invention discloses methods and apparatus for providing a variable optic insert into an ophthalmic lens. A liquid crystal layer may be used to provide a variable optic function and in some examples, an alignment layer for the liquid crystal layer may be patterned in a cycloidally dependent manner. The patterning may allow for a polarization dependent lens in some examples. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some examples, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control optical characteristics.

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 provides methods for forming an ophthalmic lens that can include a media insert and/or electronic components. In particular, the present disclosure provides for adhesion promoting functionalization steps for a biocompatible coating to bind a hydrogel material to a plastic surface or electronic component prior to the polymerization of the hydrogel. In some aspects, the media insert can be used to contain energy sources and/or functional electronic components which may be, for example, in a stacked integrated component configuration to permit a generally arcuate shape that can conform to the anterior surface of an eye.
