A retinal sleep lamp that emits light onto the eyes of the user when they are asleep which illuminates the retina through the users closed eye-lids. The lamp is used to light-adapt the eyes retinal rods to treat and prevent forms of eye disease, and regulate sleep patterns. Preferably a plurality of lamps A are positioned at various angles around the users head and may be mounted on a wall, ceiling, bed headboard or post, or freestanding, and the emitted light directed at the users head and pillow region around the head to accommodate head movement. To prevent the pillow blocking the light, the pillow is made at least partially from transparent or translucent material C, alternatively the pillow and/or the bed sheet may be made from optically reflective (B, fig 1) material, as a means to redirect the light onto the eyelids of the user. The pillow may also restrict the movement of the users head, or may include light emitting devices. The lamps can emit continuous, modulated or flashing illumination, and have a wavelength between 460nm to 520nm. The lamp emitting means may be a LED or laser. |
