History of 3D Glasses

There are many different types of 3D glasses. The most common 3D glasses (the ones with red and cyan lenses) produce a 3-dimensional effect through a process known as anaglyph color filtering. There are various other types of 3D glasses, but they all work in the same manner; by tricking the brain into seeing a 3-dimensional image from a 2-dimensional source.

History

Anaglyph images were invented in the 1853 by Wilhelm Rollmann.. The lenses in anaglyph 3D glasses were typically red and green until the 1970s, when manufacturers began using red and cyan lenses.

Function

When you view a proper source while wearing 3D glasses, each eye sees a slightly different image. These images are blended together by the brain, which produces the 3-dimensional effect.

Polarized 3D Glasses

Polarized 3D glasses are commonly used in movie theaters and function by restricting the amount of light that goes to each eye.

LCD Shutter Glasses

LCD shutter glasses are another type of 3D glasses. They work by alternately blacking out one eye at a time while a viewing screen shows a different image for each eye.

Significance

Thanks to recent advances in technology, movies utilizing polarized 3D glasses are becoming much more popular.
