3D Samsung SSG-2100AB/ZA Stereoscope Glasses.

You can only experience if you are wearing samsung 3-D active shutter glasses. These glasses have special liquid crystal lenses, each eye seeing,1080p image. Battery powered. You may need a new wafer battery #2025. I don't know if it was my imagination, but they even made just regular TV watching more 3D looking. Even with battery, that is in there now. Preowned Lenses are clear no spots or marks.
