The smart contact lens system hereby proposed, integrates a number of electronic, electro-optical or optical components on the contact lens substrate. The system, inter alia, is arranged to identify and track changes in pupillary response due to mental task engagement, also known as task-evoked pupillary response. To this end, the system proposed tracks a variety of conditions affecting reflexes such as pupillary reflex or accommodation reflex, in order to compute the extent of pupil dilation attributable to the mental task engagement. Another aspect of present invention is a smart contact lens system, which minimizes pupillary reflex caused by light by controlling the amount of light entering the eye. When pupillary reflex is non-existent, computing a task-evoked pupillary response becomes a much easier task.

A system for tracking eye movement includes a detector that is adapted to receive radiation reflected from a retina defining a spatial extent of a pupil of an eye. The detector acts to generate data indicative of a positioning of the received radiation on the detector. A processor is in communication with the detector and has software resident thereon for determining from an analysis of the data a pupil position. A controller is in communication with the processor and with a device for adjusting a direction of radiation emitted by an illumination source responsive to the determined pupil position in order to substantially center the emitted radiation on the pupil. The illumination source is preferably coaxial with the detector, and emits a beam having a diameter less than the pupil diameter.
