When most of us think about the human organ that is responsible for sight, we automatically think about the eyes. If you think that your vision is completely focused on your eyeballs, however, you’re absolutely wrong. As you view something, the eyeball focuses the light on the retina and then the rods and cones are affected by the light. After that takes place, then something rather amazing happens that most people fail to consider.
The information that is gathered by our eyes travels along the optic nerve and enters into the brain. It is then that it is interpreted by the brain that takes the data about the light we see and then uses our memory to make sense of any images that exist in the outside world. As a matter of fact, color doesn’t really exist, it is just something that exists in our mind.
When you see the following optical illusions, you will realize that not everything is as it appears. It is possible to use color, shapes and perspective to trick the eyes and the brain into seeing something that really doesn’t exist. In fact, it doesn’t matter how much you look at the object, it will still not be what you are really seeing.
