Abstract
A method for retarding or reversing progression of myopia of a viewer contains the steps of using an immersive or non-immersive device to create a plurality of image planes in the eye of the viewer. While an image plane is located on the retina, at least one image plane is not on the retina, thereby generating myopic defocus. Immersive and non-immersive devices and systems for such a method are also described.
Claims21
A method for retarding or reversing the progression of myopia of a viewer, the viewer having an eye with a retina with a central region, the method comprising the steps of:
- A) providing a non-immersive display unit comprising:
- i) a display;
- ii) a dioptric positive lens proximal to the display;
- iii) a fully-reflective mirror opposite the dioptric positive lens from the display;
- and
- iv) a semi-transparent mirror distal from the fully-reflective mirror;
- B) forming a primary visual content on the display;
- C) refracting the primary visual content through the dioptric positive lens to form a primary optical channel;
- D) redirecting the primary optical channel with the fully-reflective mirror to the semi-transparent mirror;
- E) forming a secondary visual content into a secondary optical channel directed to the semi-transparent mirror;
- and
- F) converging the primary optical channel and the secondary optical channel into a converged optical channel,
- wherein the converged optical channel forms a plurality of image planes in the eye, wherein the image planes comprise a dioptric distance therebetween, and wherein the dioptric distance between the plurality of image planes is the difference between the optical vergence between the primary optical channel and the secondary optical channel.

- H) converging the primary optical channel and the secondary optical channel into a converged optical channel;
- and
- I) reflecting the converged optical channel off of the second fully-reflective mirror,
- wherein the converged optical channel forms a plurality of image planes in the eye, wherein the image planes comprise a dioptric distance therebetween, and wherein the dioptric distance between the plurality of image planes is the greatest difference between the plurality of image planes.
