ABSTRACT:
A holographic system which contains a multiple image hologram 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 holographic system will have its own power to illuminate said hologram. 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, or the system may contain a motor coupled to rotate said system. The system may include a clock-timer to activate said motor, and for periodically illuminating the hologram. The system may include a sound alarm to remind the viewer to utilize the holographic system.
