Optical Illusion for Testing Your Brain: People with High IQ can spot the hidden face inside Caveman’s Picture in 13 Secs!

An optical illusion is a deceptive representation of an object, person,  

or scene that tricks the brain into thinking it's seeing something different  

A wide variety of optical illusions exist, including physiological, cognitive, and physical illusions.   

When we gaze at things or images from different angles,   

our normal brains might develop different perceptions.  

Because they shed information on your perceptual processes, optical illusions might be considered a subfield of psychoanalysis.  

As an example of such ingenious representation, consider the optical illusion in which the caveman's face is concealed within the image.  

in which Superman reaches rock bottom and turns to Darkseid, rather than in a standalone Man of Steel trilogy.
