Abstract

A system comprises a head-worn optical device for monitoring one or more physiological parameters from a region of interest on, in or near the eye of a user. The device comprises a measurement sub-system positioned substantially outside the field of view of a user, and an optical beam combining element, located in the field of view, where said element is transparent to a portion of the light incident on the element, while a second portion of the light is deflected such that the measurement sub-system is able to optically access the eye via the optical beam combining element.
