A device for the application of artificial light to a user's retina is disclosed. A light source leads to a light focusing member that generates a light stream at, at least one transmission angle, to the user's retina, preventing the light from coming in contact with the user's fovea. In one embodiment, the light focusing member is a light ring containing a plurality of apertures around an outer periphery with light exiting through the apertures in a plurality of streams at a transmission angle. A vision aperture within the light ring has a periphery less than the outer periphery and is on a direct axis with the user's fovea to enable the user to maintain vision during chronotherapy. The light source can be distanced from the light focusing member and connect by a light transfer member, such as a optic fiber. In another embodiment, the light focusing member can be the frame of a pair of eyeglasses having lenses to enable user vision. The light source can be either proximate the apertures around the frame or distanced from the glasses with the light being transmitted from the light source to the glasses by a transfer member.
