Zusammenfassung:	Examples are disclosed that relate to head-mounted display (HMD) devices and methods for detecting light reflected by a user's eye. In one example, an HMD device comprises a frame, a transparent cover substrate supported by the frame, and a display substrate supported by the frame. An eye-tracking light source is affixed to the frame. The eye-tracking light source is configured to emit eye-tracking light. At least one input optical element is configured to receive the eye-tracking light. A plurality of transparent delivery waveguides are integrated with the transparent cover substrate. Each of the transparent delivery waveguides comprises an output optical element configured to output the eye-tracking light towards a user's eye. In addition, each of the transparent delivery waveguides comprises a curved portion. The HMD device further comprises a camera configured to detect the eye-tracking light reflected by the user's eye.
