- MAKE YOUR OWN GLASSES
-
- The Do-It-Yourself 3-D glasses kit supplied with Stereop-Jr contains one red
- and one blue lens, and an instruction sheet with a template. Follow the
- instructions on the sheet to make a pair of child-size glasses. If you need
- another pair for an adult, read the instructions below.
-
- It's easy to make your own glasses, but it's important to use the right
- material for the lenses. You may be able to get deep red and blue
- transparent film at an art or craft supply shop, but the best place is a
- shop that sells stage lighting filters ("gels"). Your local amateur theatre
- company might be able to help you.
-
- A company called Lee Filters makes them. Contact:

- Lee #132 (Medium Blue) and Lee #106 (Primary Red) will work well.

- This {[P05,4,7] diagram } shows you how to make a pair of 3-D glasses large enough to
- fit over most regular glasses. You can also use the diagram to test lens
- materials.
-
- If you have a 14-inch monitor, the glasses shown in the diagram will be close
- to the actual size, and you'll be able to trace them directly off the screen.
- If the yellow box around the diagram isn't around 25.7cm wide and 14cm high,
- you may be able to adjust your monitor's horizontal and vertical sizes.
-
- Use tracing paper and a soft fine-point marker. Just make a dot at each
- corner, then transfer the image to a piece of light cardboard (black is
- best) by pushing a pin through each dot. Then connect the pin-pricks with
- a ruler and pencil. Cut out two centre pieces and two ear pieces.
-
- Cut red and blue lenses, each 4.2 by 2.7cm. Cut narrow strips of double-
- sided tape and place them on one centre piece as shown in the diagram.
- Centre the filters over the eye holes (red for left eye, blue for right) and
- place them carefully over the tape. Carefully align the other centre
- section over the first one and press them firmly together. Stick on the ear
- pieces with more tape.
