How to Make Homemade 3D Glasses
3-D television is an optical illusion caused by each eye interpreting a different image of the same event at the same time. A simple way to create different images from the same event is to use two different colors to make the images -- a technique that's been used for years. The 3-D glasses you need to enjoy the benefit of these juxtaposed colors aren't difficult to make.
Things You'll Need
- Poster board
- Utility knife
- Double-sided tape
- Plastic wrap; two different colors
Cut out a long rectangle that is 2 inches wide and 16 inches long from a piece of poster board.
Draw a line 4 1/4 inches from each end with a pencil. The area in the middle will contain the eye holes, while the ends will become the earpieces. Draw another line 1/2 inch from each end.
Connect the two lines on each side of the strip with a third line that runs between them. It should extend through the middle of the strip. Cut the bottom rectangle out on each side with scissors to create the earpieces.
Make a mark 1 inch inward from the each of the middle lines and 1/2 inch from the top of the strip; make a similar mark 1/2 inch from the bottom of the strip. Make two more marks 1 1/2 inches closer to the center of the strip at the same distances from the top and bottom.
Connect the marks on each side to create two boxes, then cut them out using a utility knife. They are the eye holes. Carefully place double-sided tape around their perimeters.
Cut a 2-inch square from a sheet of colored plastic wrap, then cut the same size square from a different-colored sheet of plastic wrap. Affix one square to each eye hole, pulling the plastic as taut as possible.
Slice a slit that extends halfway up the center of the glasses. Measure a 1/4-inch to the left of the notch and cut diagonally to the center. Repeat this on the other side to create a notch for your nose.
Fold each earpiece inward and then out again to crease them properly.
- The preferred colors for the plastic wrap are red and blue.
- If you are making these glasses to enjoy a certain movie or television show, it is important to find out which colors the film uses before starting.
