What are the red and blue glasses called? Anaglyph glasses: Classic red and blue

What do red and blue glasses do?

Using a red and blue lens 'tricks' the brain into seeing a 3D image. Each eye sees a slightly different image. The eye covered by the red lens will perceive red as "white" and blue as "black," and vice versa for the other eye. This disparity mimics what each eye would see in reality, as with most 3D technology.

How does red cyan 3D glasses work?

These glasses utilize special red / cyan lenses to interpret the image. These lenses produce the images you see by color filtering the layered image that you're actually looking at. While one lens filters out all the red in an image, the other lense filters out the cyan, causing your brain to see the picture in 3D.

Why are 3D glasses no longer red and blue?

The blue lens filters out all the red light, and the red lens filters out all the blue light, so each eye sees a slightly different image. When the 3-D movie is projected on the screen, two images are displayed: one in red, one in blue. Since each lens of the glasses has a filter, only one image can reach each eye.

How do 3D glasses work?
