Abstract
In one embodiment, a system for monitoring eye movement through optical observation of the eye includes an optical device configured for mounting on a frame for positioning the optical device on a user. The optical device includes a light source configured for emitting light along a first path and a sensor positioned in the optical device to receive light from a second path substantially parallel to the first path. A reflector is located within a lens connected to the frame and configured when positioned on the user to reflect light emitted by the light source onto the eye and reflect light reflected by the eye back to the sensor. The reflector covers only a portion of the lens.
