These are the "Classic" Anaglyph 3D Paper Glasses from the 50's! Updated for modern viewing with Magenta/Green Lenses. Some DVD movies are using Magenta/Green lenses instead of the traditional Red/Blue. Regular 3D glasses won't work, you will need this color combo.
Same as the glasses used for DVD movies like Journey to the Center of the Earth, Coraline, Monsters & Aliens and others.
