Optical illusions are a fascinating interplay of principles of physics, physiology and psychology. We are often deceived by certain images, due to reasons related to light, geometry and the peculiar way our senses work. If we look around us, many such phenomena can be observed in our everyday lives.

Optical illusions displayed in the Mathematics lab and the Quadrangle at the Centre are the most fascinating and inquired about exhibits that we have always attracted visitors. They have never failed to intrigue both children and adults, and motivate them to observe, explore, ponder over, and seek answers.

An optical or visual illusion is a kind of illusion in which the images perceived through the sense of sight tend to be misleading or deceptive.
