Optical Illusions in Our Life
Optical Illusion is defined as the wrong perception of our brain that does not tally with the actual physical measurements of stimulating objects. This is happening because of the presence of neighbouring objects which make our eyes to gather wrong information and send it to our brain. Generally optical illusions happen due to many factors including color, size, angle and so on. Let us see some of the interesting optical illusion pictures here below.
