ELECTRONIC OPHTHALMIC LENS WITH PUPIL CONVERGENCE SENSOR Russian patent published in 2016 - IPC A61B3/11 G02C5/00 G02C7/04 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to ophthalmology. Ophthalmic lens with power supply comprises contact lens or intraocular lens, which includes optical zone and peripheral zone; and system for identifying position and convergence of pupils built into peripheral zone of contact lens. System for recognising and convergence pupils includes sensor for determining position of pupils, wherein sensor has at least one photo transducer configured to recognise different sequences of blinking and/or blinking templates in different conditions of illumination intensity, data exchange device configured to send and receive information at least in/out of second position identification and convergence of pupils systems, built-in in peripheral zone of second contact lens, system controller connected to sensor and device for data communication and configured to determine position and convergence of pupils based on information obtained from sensor and second position identification and convergence of pupils systems, and output control signal, and at least one actuator configured to receive output control signal and perform preset function, wherein system controller is configured to at least one of information collection and storage of sensor and output control signal. At that, system controller is also configured to output control signal when given threshold value passed.

EFFECT: using given group of inventions enables higher accuracy of correction of vision.
