Humans use what is known as binocular vision to perceive depth and see the world in 3D. The binocular vision system relies on the fact that we have two eyes, which are separated by a small distance. This separation causes each eye to see the world from a slightly different perspective. The brain fuses these two views together. It understands the differences and uses them to calculate distance, creating our sense of depth and ability to gauge distance. Red and blue 3D glasses attempt to mimic normal sight, and to play a trick on the brain. This is done by creating two very similar images on a flat surface, one overlaying the other. The first image is in red, and the second image is in blue. In 3D glasses the right lens is usually red, and the left usually blue in color. This means that the right eye picks up the first image, and the left eye picks up the slightly different image. The slight difference in perspective, and the fact that each eye can only see one image which looks to be the same one, creates an illusion of 3D. Compare the 3-Dimensional Holographic Effect capabilities of high definition glasses incorporating ChromaDepth® optics to that of the standard Red/Blue color lens 3D glasses.
