Abstract
The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a selection layer configured to reject light from the eye within a first range of incident angles and allow light from the eye within a second range of incident angles to pass through the selection layer. The sensor system may comprise a plurality of photodiodes disposed below the selection layer and configured to detect the light from the eye within the second range of incident angles that is allowed to pass through the selection layer. The sensor system may comprise an output circuit electrically coupled to the plurality of photodiodes and configured to output a signal indicative of which photodiode of the plurality of photodiodes detected the light.
