Methods and viewing systems for inhibiting ocular refractive disorders from progressing

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

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,

wherein 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.

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 secondary image generates myopic defocus.

4 . A method for reducing hyperopia of a viewer, the viewer having a retina with a central region, the method comprising the step of:

providing an object in front of the viewer to provide a primary image;

providing a transparent layer between the viewer and the object; and

providing a secondary image on the transparent layer,

wherein 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.

5 . The method according to claim 4 , wherein the primary image is focused on the retina.

6 . The method according to claim 4 , wherein the secondary image generates hyperopic defocus.

7 . The method according to claim 1 or 4 , wherein the transparent layer has an adjustable transparency.

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

9 . The method according to claim 1 or 4 , comprising a contrast enhancement technology.

10 . An optical system comprising:

a transparent layer, the transparent layer adapted to provide a primary image and a secondary image,

wherein said secondary image is provided by an object behind the transparent layer being viewed through the transparent layer by a viewer having a retina.

11 . The optical system according to claim 10 , wherein the secondary image is focused in front of the retina to generate myopic defocus.

12 . The optical system according to claim 10 , wherein the primary image is focused behind the retina to generate hyperopic defocus.

13 . The optical system according to claim 10 , wherein the primary image and the secondary image are viewed simultaneously by the viewer.

14 . The optical system according to claim 10 , wherein the transparent layer has an adjustable transparency.

15 . The optical system according to claim 10 , the optical system further comprises a supporting structure connected to the transparent layer.

16 . The optical system according to claim 10 , wherein the primary image has at least one edge, wherein the edge is surrounded by a contrasting color.

17 . The optical system according to claim 10 , wherein the optical system comprises an electronic device.

18 . The optical system according to claim 10 , wherein the optical system is used for retarding or reversing the progression of a refractive disorder.

19 . An optical system comprising at least one layer, the at least one layer adapted to display a primary image and a secondary image generated by a computer program, the primary image and the secondary image are simultaneously viewable by a viewer having a retina with a central region, wherein the primary image is focused on the retina, and the secondary image is focused in front of or behind the central region.

20 . 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.

21 . The method according to claim 20 , wherein the primary image is focused on the retina.

22 . The method according to claim 20 , wherein the secondary image generates myopic defocus.

23 . The method according to claim 20 , wherein the reflective surface has an adjustable reflectance.

24 . The method according to claim 20 , wherein the primary image is focused on the retina by ocular accommodation of the viewer or by using optical lens.

25 . The method according to claim 20 , comprising a contrast enhancement technology.

26 . An optical system comprising:

a layer having a reflective surface, the layer adapted to provide a primary image and a secondary image,

wherein the secondary image is provided by a reflection of an object facing the reflective surface, the primary and the secondary images are viewable by a viewer having a retina.

27 . The optical system according to claim 26 , wherein the secondary image is focused in front of the retina to generate myopic defocus.

28 . The optical system according to claim 26 , wherein the reflective surface has an adjustable reflectance.

29 . The optical system according to claim 26 , the optical system further comprises a supporting structure connected to the layer.

30 . The optical system according to claim 26 , wherein the primary image has at least one edge, wherein the edge is surrounded by a contrasting color.

31 . The optical system according to claim 26 , wherein the optical system comprises an electronic device.

32 . The optical system according to claim 26 , wherein the optical system is used for retarding or reversing the progression of myopia of the viewer.
