Making Red-Blue 3D Glasses

Three-dimensional or 3D effects were common in 1950s horror movies, 1990s posters and postcards and other entertainment media over the years. Today, stereoscopic glasses have come back into fashion as children's movies and Internet videos regularly use 3D effects. Without 3D glasses, stereoscopic pictures and videos appear blurry or fuzzy. You can easily make your own inexpensive glasses with common household materials.

Instructions

    • 1

      Select a clear, unscratched CD jewel case or pair of glasses with clear lenses that aren't being used. Once you make the glasses into 3D glasses, you won't be able to use them normally anymore.

    • 2

      Color the left glasses lens with a red permanent marker until the lens is completely red. On the right lens, use a blue marker.

      For the jewel case version, draw and fill in a red rectangle on the left side of the case piece. Draw the rectangle large enough to cover your left eye. Draw and fill in a blue rectangle of the same size about one centimeter apart from and to the right of the red rectangle.

      Put on the glasses or hold the CD jewel case up to your eyes. You are now ready to view a stereoscopic image.
