Our amazing Optical Illusion!

I am sure, everyone have learn this in your secondary school or college, it'a basic science and one of the amazing fact about our eyes' visions created by the Greatest One, Allah SWT. So an optical illusion is characterized by visually perceived images that differ from objective reality, the information gathered by the eyes is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. In a simple words, we may see something that is not there or fail to see something that is there or even see something that different from what is there! It's an illusion! *Fuh! I'm sweating* You get me?
