Abstract
An optical device, such as spectacles or goggles, has a segmented display (3) formed in a transparent substrate by directing light from a number of light sources (15) through respective light guides (14) and reflecting the light out of the transparent substrate at the ends of the light guides (14) to form individually illuminable segments (13). The device has the advantage that an electronically-generated display can be displayed to a viewer in combination with the image transmitted through the transparent substrate simply and relatively inexpensively.
