Abstract
An illuminated eyewear device is described. The illuminated eyewear device comprises a transparent substrate and one or more light sources mounted around the perimeter of the transparent substrate. The output of the one or more light sources is arranged to be coupled into, and propagates within, the transparent substrate. Applied to an inner surface of the transparent substrate are a plurality of refractive light scattering means designed to break the condition for total internal reflection of the light generated by the one or more light sources. As well as being mobile, compact and easy to integrate into everyday life, the above described illuminated eyewear device address the known problem of glare experienced by users of those devices known in the art since the light sources are not directly imaged into the user eye.
