The plurality of light detectors is disposed within the transparent lens and is configured to receive light that is emitted from the at least one light source and is reflected off of the eye. Each of the light detectors is transparent to visible light and is configured, upon receipt of light that is reflected off of the eye, to supply an output signal.
