Optical Illusions By Latisse
An optical illusion is like magic in that things are not what they perceive to be in reality. Our five senses – sight, hearing, taste, touch, and smell – are there to help us cope with the environment; but 75 percent of the information humans receive comes from our sight, which makes it the most important of the five senses. Optical illusions come into play when differences occur between our perceptions and the image viewed by the eye. Our brains are trying to interpret what we see. Sometimes, we create a perception that in reality does not match the real image. Optical illusions trick our brains into seeing things that may or may not be real. Here are some fun optical illusions to try out and see if your brain can accurately interpret the images from your eyes.

Physical Illusions
This site explains physical illusions as being mirages, which are caused by an optical phenomenon. What we see is not really there, but the cause of the illusion is in the behavior of light before it reaches the eye.
Inferior mirage
The most commonly observed mirage that is viewed not only mirrored upside-down, but is a mirage of an object seen below that object. A shiny patch on a hot surface that is the reflection of the sky is an example of an inferior mirage. The mirage makes the horizon look lifted up and inverted downwards, causing inferior mirages to be seen over lakes or oceans because these surfaces are long and flat.
Physiological illusions
These happen as the result of rapidly alternating patterns, movement, tilt, changes in color and brightness through flickering or caused by the ‘blind-spot.’ The blind-spot is the area of the eye that has no photoreceptors because the space is filled by the optic nerve.
‘Blind-Spot’ Illusion
This occurs when the eye looks at something specific in space and the brain fills the space with the same color that it sees at that moment.
The Necker Cube
See if you can figure out if the green dot is located in the lower left front or lower left rear of the cube.
