Abstract

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

First claim

What is claimed and desired to be secured by Letters Patent of the United States is:

1. Glasses for 3D viewing comprising:
a frame for 3-D lenses, the frame configured to hold 3-D lenses for 3-D viewing, the 3-D lenses further comprising a 3-D right lens and a 3-D left lens, and the frame further comprising snap rings, the snap rings configured to hold the 3-D lenses in place when the snap rings are mechanically mated to the frame;
at least one removable temple, the at least one removable temple removably attached to the frame for 3-D lenses, wherein the at least one removable temple further comprising a cavity, the cavity configured to house a sensor;
a cover, the cover configured to attach to the at least one removable temple;
wherein the cover provides a seal for the cavity; and
further wherein the snap rings further comprise textured areas, and the textured areas being substantially non-reflective.

2. The glasses for 3D viewing according to claim 1 , wherein at least one of the removable temples comprise a pin configured to be inserted into a receptacle on a frame of the viewing glasses.

3. The viewing device according to claim 1 , wherein the glasses are part of a set of glasses that are re-used by different members of the public at a digital cinema, washed between use, and include smooth areas on portions of the glasses that generally contact a user during viewing use of the glasses.

4. A viewing device, comprising:
a frame for 3-D lenses;
a 3-D right lens and a 3-D left lens, the 3-D right lens and the 3-D left lens mechanically mated to the frame for 3-D lenses by a snap ring;
a set of temples, the set of temples mated to the frame for 3-D lenses;
wherein the snap ring further comprise textured areas, and the textured areas being substantially non-reflective.

5. The viewing device according to claim 4 , wherein the device further comprising lenses and a retaining mechanism that is a same width or wider at a front side of the lenses compared to a back side of the lenses.

6. The viewing device according to claim 4 , wherein device comprise a retaining mechanism comprising a snap ring at a front side of the lenses.

7. The viewing device according to claim 6 , wherein the retaining mechanism brings at least one point of the lenses as close to the viewer's eyes as possible.

8. The viewing device according to claim 4 , wherein the 3-D right lens and the 3-D left lens further comprising spectrally separated filter lenses and a shelf at a top of a frame holding the spectrally separated filter lenses.

9. The viewing device according to claim 8 , wherein the shelf is configured to rest on a separate pair of prescription glasses and optically align lenses of the prescription glasses to the spectrally separated filter lenses of the viewing device.

10. The viewing device according to claim 9 , wherein the shelf is configured to rest on top of the separate pair of prescription glasses, bringing a sweet spot of the spectrally separated filter lenses into an optimal position for content viewing.

11. The viewing device according to claim 9 , wherein dimensions of the device are designed to fit over a majority of separate pairs of prescription glasses.

12. The viewing device according to claim 11 , wherein an inner frame portion of the device is 146 mm wide.

13. The viewing device according to claim 8 , wherein the spectrally separated filter lenses are configured to spectrally separate wide-band lights.

14. The viewing device according to claim 4 , wherein the right lens and the left lens further comprising spectrally separated filter lenses configured to spectrally separate narrow band lights.

15. The viewing device according to claim 4 , further comprising at least one of Radio Frequency Identification (RFID) and sensormatic tags.

16. The viewing device according to claim 15 , wherein at least one of the tags is utilized in an accountability program.

17. The viewing device according to claim 15 , wherein at least one tag is embedded in the glasses.

18. The viewing device according to claim 15 , wherein at least one of the tags is embedded in at least one temple of the glasses.

19. The viewing device according to claim 15 , wherein the tags are embedded in opposing temples of the glasses.

20. The viewing device according to claim 15 , wherein the glasses are adapted to fit average child size heads.

21. Glasses for 3D viewing comprising:
a frame for 3-D lenses, the frame configured to house a 3-D right eye lens and a 3-D left eye lens, wherein the frame comprises a set of right eye lens key spaces and a set of left eye lens key spaces in corresponding lens retaining areas of the frame;
wherein a snap ring for the 3-D right eye lens further comprises a set of right eye lens keys and a snap ring for the 3-D left eye lens further comprises a set of left eye keys, the right eye lens keys and left eye lens keys configured to mate into the set of right eye lens key spaces and the set of left eye key spaces respectively on the frame for 3-D lenses on the corresponding lens retaining areas of the frame; and
wherein the snap ring further comprise textured areas, and the textured areas being substantially non-reflective.
