The world is full of optical illusions and things aren’t always the way they appear. Although our mind is constantly trying to make sense of the world around us it can sometimes get a little out of control and make us start to see things…literally.
While some of the optical illusions on our list are relatively famous, others are a bit more obscure but all of them give us a glimpse into our amazingly complex minds.
There is no magic involved, no strings attached, its all in your head. Here are 25 of the most incredible optical illusions you will find.
Found in virtually every psychology textbook in the world, the two monsters in this optical illusion are in fact the same size. Your brain automatically adjusts images that it perceives to be distant in order to compensate for the fact that they are larger than they seem.
Named after Robert Jastrow in 1889, the bottom figure appears to be larger although they are both the same size. This is because the shorter edge of “A” is directly adjacent to the longer edge of “B”.
First described by British psychologist James Fraser in 1908, this illusion is also known as the “false spiral”. While it appears that the overlapping arcs are spiraling into infinity they are in fact only a series of concentric circles.
This is a variation of the Hermann Grid where black dots appear and disappear at the intersections of the gray lines. Interestingly enough, if you cock your head at a 45 degree angle the effect is reduced (but not eliminated).
Blue vs Green
There are several variations to this optical illusion but the effect is the same. The “blue” and “green” backgrounds are in fact the same color (open it in photoshop).
