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.

Claims (7)

1. A method for retarding or reversing progression of myopia a viewer, the viewer having a retina with a central region, the method comprising the steps of:

providing a layer having a reflective surface, said reflective surface facing the viewer;

providing an object facing the reflective surface; providing a primary image on the layer, said primary image being viewable by the viewer; wherein the reflective surface allows reflection of the object to be viewed by the viewer as a secondary image, with the secondary image being focused in front of the central region of the retina; wherein the secondary image generates myopic defocus.

2. The method according to claim 1 , wherein the primary image is focused on the retina.

3. The method according to claim 1 , wherein the reflective surface has an adjustable reflectance.

4. The method according to claim 1 , wherein the primary image is focused on the retina by ocular accommodation of the viewer or by using optical lens.

5. The method according to claim 1 , comprising a contrast enhancement technology.
