Abstract

A set of eyewear is provided for use with prescription spectacles. The design comprises a plurality of selecting devices formed and configured to be attached to the spectacles to provide stereoscopic viewing of images when worn by a user wearing the spectacles. The eyewear comprises a substrate forming a first selector device and a second selector device, and optical materials provided on the substrate. The optical materials comprise first optical material associated with the first selector device and providing a first orientation along a first axis and second optical material associated with the second selector device and providing a second orientation along a second axis substantially orthogonal to the first axis. The substrate and optical materials are configured to be fixedly mountable to the spectacles.

Claims

1. A set of eyewear for use with prescription spectacles, comprising:

a plurality of selecting devices formed and configured to be attached to the spectacles to provide stereoscopic viewing of images when worn by a user wearing the spectacles.

2. The set of eyewear of claim 1, wherein the plurality of selecting devices each comprise a substrate having a quarter-wave retarder located thereon.

3. The set of eyewear of claim 2, wherein the quarter-wave retarder for a first selecting device is oriented along a first axis and the quarter-wave retarder for a second selecting device is oriented along a second axis substantially orthogonal to the first axis.

4. The set of eyewear of claim 1, wherein said plurality of selecting devices comprise a plurality of tabs configured to enable placement of the eyewear between the spectacles and the user.

5. The set of eyewear of claim 1, wherein said plurality of selecting devices comprise means for affixing the set of eyewear to the spectacles.

6. The set of eyewear of claim 1, wherein said plurality of selecting devices comprises a curved ridge configured to affix the plurality of selecting devices to the spectacles.

7. The set of eyewear of claim 1, wherein the plurality of selecting devices comprise a relatively clear plastic substrate without a polarization property having at least one polarizer provided thereon.

8. The set of eyewear of claim 7, wherein one linear polarizer associated with one selecting device has a first orientation along a first axis and another linear polarizer associated with another selecting device has a second orientation along a second axis orthogonal to the first axis.

9. A set of eyewear for use with spectacles worn by a user when viewing stereoscopic images, comprising:

a substrate forming a first selection device and a second selection device;

optical materials provided on the substrate, the optical materials comprising;

first optical material associated with the first selection device and providing a first orientation along a first axis; and

second optical material associated with the second selection device and providing a second orientation along a second axis substantially orthogonal to the first axis;

wherein the substrate and optical materials are configured to be fixedly mountable to the spectacles.

10. The set of eyewear of claim 9, wherein the set of eyewear is configured to be positioned between the spectacles and eyes of the user.

11. The set of eyewear of claim 9, wherein the substrate is a substantially clear plastic and the optical materials comprise a polarizer.

12. The set of eyewear of claim 9, wherein the substrate comprises a linear polarizer substrate and the optical materials comprise a quarter wave retarder.

13. The set of eyewear of claim 9, wherein said plurality of selecting devices comprise a plurality of tabs configured to enable placement of the eyewear between the spectacles and the user.

14. The set of eyewear of claim 9, wherein the substrate and the optical materials are fixedly mountable to the spectacles using a curved ridge attached to the substrate and optical materials.

15. The set of eyewear of claim 9, wherein the substrate and the optical materials are fixedly mountable to the spectacles using a plurality of tabs configured to enable placement of the eyewear between the spectacles and the user.

16. The set of eyewear of claim 9, further comprising a frame fabricated from one from a group comprising pressed paper and cardboard.

17. A set of eyewear for use with a set of spectacles worn by a user enabling relatively clear user viewing of stereoscopic images, the set of eyewear comprising:

a first selection device and a second selection device formed of a substrate;

optical materials provided on the substrate, the optical materials comprising;

first optical material associated with the first selection device and providing a first orientation along a first axis; and

second optical material associated with the second selector device and providing a second orientation along a second axis substantially orthogonal to the first axis; and

means for fixedly mounting the first selection device and second selection device to the spectacles.

18. The set of eyewear of claim 17, wherein fixedly mounting means comprise a curved ridge attached to the first selection device and the second selection device.

19. The set of eyewear of claim 17, wherein the fixedly mounting means comprise a plurality of tabs configured to enable placement of the eyewear between the spectacles and the user.
