You won’t believe your eyes!
The way our eyes work is that we see something in front of us, our brain processes the shapes and colors, and then we have our sight. Inside our eyes are lenses, which make sense of the world around us. The direct connection between the eyes and the brain have given us opportunities to improve our vision and create some amazing effects for our entertainment. Then we have the complexity of optical illusions, where we see things that don’t exist.
In the past, optical illusions were perceived to be of witchcraft and other supernatural causes. People were imprisoned and burned at the stake for creating and promoting optical illusions.
