How to make a 3d (Red/Cyan) Glasses


  1. Download and print off a copy of the PDF. This can be downloaded fromhttp://stereo.gsfc.nasa.gov/img/glasses.pdf, or enlarge the image provided here. Cut out each piece (including the eyeholes). Stick the sides to the center to form a pair of glasses. This forms a stencil.

  2. 2
    Tape the stencil flat to the sturdy poster board, or trace around it. Cut out the glasses. Cut the eyeholes as well.
  3. 3
    Cut out lenses from the sheets of blue and red acetate. If you can only find clear acetate, color with a red and blue marker (one red, one blue lens).
    • Make sure to cut the acetate pieces a little larger than the opening for the eyes.
  4. 4
    Tape the lenses over the eyeholes. Red goes on the LEFT, and blue goes on theRIGHT.
    • Do not get tape on parts of the acetate visible through the eyehole.
