How Do 3D Glasses Work?

Posted on Thursday 2nd April 2020

3D glasses are nothing short of a technological marvel—what with the way they make your favorite movies come alive! However, have you ever wondered how 3D glasses work?

Early Forms of 3D Technology

man hand holding 3D glasses It’s easy to think 3-dimension glasses are a recent invention. However, early forms of 3D glasses can be traced all the way back to 1922. Since then, technological advancements have made them better and cheaper. And now you can even get yourself a 3D glasses kit for your own home.

How 3D Glasses Work

While technology may get all the credit, 3D glasses work through a combination of filters and your brain. The two filters (lenses on the glasses) feed your eyes two images taken from slightly different perspectives. Your brain then combines the input your eyes get from the filters into a single image. This results in images that have depth.

Red/Green vs. Red/Blue

3D glasses are popularly known for their red/green or red/blue lenses. These act as filters that allow only one image through. As a result, your eyes receive two different images that the brain then combines, giving the images “depth”—the 3D effect.

Polarized 3D Glasses

Polarized 3D glasses use two lenses with different polarization as opposed to color in traditional 3D glasses. This results in each lens only allowing one of the images into each eye. Again, when the brain receives these two images, it creates an illusion of depth.

Now You Know How 3D Glasses Work

Next time you set your 3D glasses down next to your TV remote control, remember how those 3D glasses work. If you don’t have a pair yet, spoil yourself with a 3D glasses kit and enjoy an immersive entertainment experience.
