Embodiment Construction

[0043] Ophthalmic devices may include contact lenses. Conventional contact lenses are polymeric structures with specific shapes to correct various vision problems as briefly described above. To achieve enhanced functionality, various circuits and components can be integrated into these polymer structures. For example, control circuits, microprocessors, communication devices, power sources, sensors, actuators, light-emitting diodes, and miniature antennas can be integrated into contact lenses through custom optoelectronic components to not only correct but enhance vision, as well as provide Additional functionality as explained herein. Electronic and / or powered contact lenses can be designed to provide enhanced vision via zoom-in and zoom-out capabilities or simply modifying the optical power of the lens. Electronic and / or powered contact lenses can be designed to enhance color and resolution, display texture information, convert speech to subtitles in real time, provide visu...

Abstract

The invention provides capacitive sensing circuits and methods for determining eyelid position using the same. The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a first electrode configured to be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, a second electrode configuredto be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, and a system controller cooperatively associated with the first electrode and the second electrode to receive a capacitance measurement therefrom, the system controller configured to determine a position of one or more of the upper eyelid and the lower eyelid in spatial coordinates based on the capacitancemeasurement received from the first electrode and the second electrode.

Description

Background technique [0001] 1. Technical field [0002] The present disclosure relates to electronic ophthalmic devices, such as wearable lenses including contact lenses, implantable lenses including intraocular lenses (IOLs), and any other type of device including optical components, and more particularly, to methods for determining An individual's eyelid position to activate and control the sensors and associated hardware and software of the electronic ophthalmic device. [0003] 2. Discussion in related fields [0004] Lenses such as contact lenses and intraocular lenses are currently used to correct vision defects such as nearsightedness (nearsightedness), hyperopia (hyperopia), presbyopia and astigmatism. However, properly designed lenses incorporating additional components can be used to enhance vision as well as correct vision defects. [0005] Conventional contact lenses are polymeric structures with specific shapes to correct various vision problems as briefly d...
