How Do You Make 3D Video Polarized Glasses?
Polarized glasses create the impression of 3D by restricting some light waves from reaching your eyes. The polarizing plastic filters out all light waves, except for the ones going in a certain direction. This is called stereoscopy. You can make your own polarizing glasses using a frame from an old pair of regular glasses and some polarizing plastic. Step 1 Use your thumbs to push out the old lenses. Step 2 Cut two pieces of polarizing plastic about twice the size of the old lenses. Step 3 Hold the pieces of plastic one on top of the other. Rotate the top one until the area where they overlap becomes dark. At this point, the polarization of the two pieces of plastic will be perpendicular to each other. In other words, one will have vertical polarization, the other horizontal. Step 4 Keeping the plastic oriented in the same direction as in Step 3, use the old lenses to trace the shape of the new polarizing lenses. Step 5 Cut out the new lenses from the plastic used in Steps 3 and 4, pro
