FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine. A powered ocular lens comprises: a contact lens with optical and peripheral portions, or an intraocular lens, a power source and an eyelid position sensor system integrated into the contact lens or an intraocular lens, particularly into its peripheral portion. The eyelid position sensor system comprises: a sensor array having a set of separate sensors vertically mounted in different positions on the contact lens to detect an eyelid position; a system controller configured to select one particular eyelid position sensor in the array and provide an output drive signal, and also an actuating device configured to receive the output drive signal and perform a preset function.
EFFECT: using this group of inventions is expected to obtain more reliable and accurate data on user's eyelid positions.
