Do you know the first popular 3D glasses?

Now 3D glasses can be seen everywhere. Although there are many different kinds of 3D glasses, they all work to achieve the same end result. In a nutshell, they are essentially trying to trick your brain into seeing a 2 dimensional image projected by a TV set or cinema screen as a 3 dimensional image.

Most people can remember the first 3D glasses from years ago that were designed to work with anaglyph color filtering. These glasses were usually made out of cardboard with one red lens and one cyan lens; although before 1970 red and green lenses were used.

Anaglyph color filtering was invented in 1853 by Wilhelm Rollmann. The red and cyan anaglyph 3D glasses work by making each eye see a different image. The brain then makes these two images blend together, and the result of this is a 3D image effect.

Theses glasses enjoyed a fair amount of popularity in the past because of the fact that they were the cheapest ones available to view 3D entertainment; however it wasn’t long until people started looking around for new, more effective ways to see in 3D.
