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 ### Claim 1 A set of eyewear for use with spectacles comprising a front piece and a plurality of temple pieces attached thereto, comprising: a plurality of selecting devices formed and configured to be slipped onto the front piece of the spectacles in a slip-in, self-locating detachable manner to provide stereoscopic viewing of images when worn by a user wearing the spectacles, wherein each selecting device comprises a linear polarizer substrate and a quarter wave retarder. ### Claim 2 (depends on 1) The set of eyewear of claim 1, wherein the plurality of selecting devices each comprise a substrate having the quarter-wave retarder located thereon. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) The set of eyewear of claim 1, wherein said plurality of selecting devices comprise means for affixing the set of eyewear to the prescription spectacles. ### Claim 6 (depends on 1) 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 prescription spectacles. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 7) 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. ### Claim 9 A set of eyewear for use with spectacles worn by a user when viewing stereoscopic images, the spectacles comprising a front piece and a plurality of temple pieces, the set of eyewear comprising: a substrate forming a first selection device and a second selection device; and 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 set of eyewear is configured to be slipped onto the front piece of the spectacles in a slip-in, self-locating detachable manner and the substrate and optical materials facilitate viewing of stereoscopic images, and wherein the substrate comprises a linear polarizer substrate and the optical materials comprise a quarter wave retarder. ### Claim 10 (depends on 9) 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. ### Claim 11 (depends on 9) The set of eyewear of claim 9, wherein the substrate is a substantially clear plastic and the optical retarder materials comprise a polarizer. ### Claim 12 (depends on 9) 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. ### Claim 13 (depends on 9) 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. ### Claim 14 (depends on 9) 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. ### Claim 15 (depends on 9) The set of eyewear of claim 9, further comprising a frame fabricated from one from a group comprising pressed paper and cardboard. ### Claim 16 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 spectacles comprising a front piece and a plurality of temple pieces, the set of eyewear comprising: a first selection device and a second selection device formed of a substrate; and optical materials provided on the substrate, the optical materials comprising: first optical material associated with the first selection device; and second optical material associated with the second selection device; wherein the set of eyewear is configured to slip onto the front piece of the spectacles in a slip-in, self-locating detachable manner and the first selection device, second selection device, and optical materials facilitate viewing of stereoscopic images, and wherein the substrate comprises a linear polarizer substrate and the optical materials comprise a plurality of quarter wave retarders. ### Claim 17 (depends on 16) The set of eyewear of claim 16, wherein the set of eyewear is configured to detachably slip onto the front piece of the spectacles using fixedly mounting means comprising a curved ridge attached to the first selection device and the second selection device. ### Claim 18 (depends on 16) The set of eyewear of claim 16, wherein the set of eyewear is configured to detachably slip onto the front piece of the spectacles using fixedly mounting means comprising a plurality of tabs configured to enable placement of the eyewear between the spectacles and the user.
