Abstract: A head-mounted device (10) may have a housing (12) with a frame (12F) that supports lenses. Each lens may have a positive bias lens element and a negative bias lens element (16N). A waveguide may overlap the lens. During operation, images from the waveguide may be provided to an eye box (20) through the negative bias lens element. An eye sensor such as a gaze tracking camera (32) may operate through the negative bias lens element (16N). The negative bias lens element may have a protruding portion (38) through which the sensor operates, may have a surface (36) facing the sensor that has a curved surface to provide a desired lens characteristic, may have a prism (40) for helping to couple light from the eye box (20) to the eye sensor, and/or may have other features to facilitate use of the eye sensor to monitor the eye of a user in the eye box (20).
