Just Like 3D Glasses

The way our eyes work is the inspiration behind countless visual tricks. One of such was also a huge ’90s fad, much like Magic Eye pictures. And yes, we’re talking about those old-school 3D glasses that came with a red lens and a blue lens.

If you used these bi-colored glasses to watch a movie, the two different lenses tricked your brain into thinking that some of the images were popping out of the screen. In fact, this sort of 3D picture looks almost exactly like the 3D images revealed in Magic Eye pictures. Just like stereograms, 3D glasses play with our binocular perception of depth.
