Do you understand the scientific principles that make polarized free 3D glasses work? This has always seemed a bit of a mystery to me — but from what I can understand the polarized lenses filter the light in such a way that all of the light beams will be oriented so that they go in an identical direction. You may not be familiar with these glasses, yet if you have ever attended a laser light show you have probably worn them, as they are commonly used at these events. Another place where you will see these glasses used is in school science classes, where the children are studying the physical properties of light and light waves.
