Abstract: A method for retarding or reversing progression of myopia of a viewer includes providing an object in front of the viewer; providing a transparent layer between the viewer and the object; and providing a primary image on the transparent layer, the transparent layer allows the viewer to see the object as a secondary image simultaneously with the primary image, wherein the secondary image is focused in front of the central region of the retina. A method for reducing hyperopia of a viewer includes providing an object in front of the viewer to provide a primary image; providing a transparent layer between the viewer and the object; providing a secondary image on the transparent layer, the transparent layer allows the viewer to see the primary image simultaneously with the secondary image, wherein the secondary image is focused behind the central region of the retina. Other systems are also described herein.
