Why are people with a lazy eye unable to perceive 3D in 3D films?
3D films used polarized light to create the effect. The footage is shot with 2 cameras, and projected through 2 projectors with different polarizing filters, one vertically polarized and the other horizontal. The 3D glasses are also filters, only allowing light of a vertical polarization to enter…
The Short Answer
3D films used polarized light to create the effect. The footage is shot with 2 cameras, and projected through 2 projectors with different polarizing filters, one vertically polarized and the other horizontal. The 3D glasses are also filters, only allowing light of a vertical polarization to enter one eye, and light of a horizontal polarization to enter the other eye. The brain combines the images to form an image, and that's where the 3D effect comes together. (Read more [here](_URL_0_)). From what little I know of Amblyopia (lazy eye), both eyes are still functional, but since the one eye is misaligned the brain ignores the image from it when forming the image in your brain. The two-camera effect is lost, since your brain is only 'seeing' the film from one of the cameras and ignoring the other one. You're essentially watching a standard one-camera production, the only difference being you're watching it through a polarizing filter.
