ABSTRACT:
An optical system which contains multiple images comprised of two or more images at varying focal distances, which when viewed consecutively and in repetition will exercise the ciliary muscle of the eyes. The optical system may have its own power to illuminate said images. The shifting of conditions of the viewer to alternate the viewing of one image and then the other, may involve the physical movement of the user's head, the system may contain a motor coupled to rotate said system, or the configuration of the lighting source(s) shall illuminate one image and then another. The system may include a clock-timer and control of the variable speed of illumination between one optical image to another. The system may include a sound alarm to remind the viewer to utilize the holographic system.
