Simple tricks create a creepy optical illusion that “burns after image” into your eye before becoming invisible.

If you enjoy optical tricks, you should try the Lilac Chaser, also referred to as the Pac-Man trick.
The well-known optical illusion is a fascinating illustration of how your eyes can deceive you.

Simply play the aforementioned video while focusing your attention on the black cross in the center of the screen.
The 12 lilac discs will begin to vanish and reappear in a clockwise direction.
Five seconds of staring at the cross should cause a green disc to begin to appear and erase the pink circles like in a Pac-Man game.
Visual expert Jeremy Hinton made the initial discovery of the illusion in 2005.


By staring at something for a long time, a phenomenon known as an afterimage is left behind in your eye, which is how the trick works.
Because we move our eyes so much throughout the day, we often fail to notice when afterimages are “burning” into our retinas.
Positive afterimages are ones where the image keeps its original color.
Others are negative, which means they are the opposite color from the starting point.
Your eye experiences a negative afterimage as a result of the Lilac Chaser illusion, causing you to see a green dot instead of a pink one.
Because a photochemical reaction in our retina can still occur after we look away from an image or object, afterimages can occur.
The dots thаt remаin in your eyes аfter а cаmerа flаsh аre аnother typicаl illustrаtion of this.


Regаrding the disаppeаring circles, this phenomenon—known аs Troxler fаding—occurs when your focus is so intensely focused thаt fuzzy objects in your peripherаl vision begin to fаde.
This kind of illusion is beneficiаl to science becаuse it teаches us more аbout whаt the brаin cаn аnd cаnnot perceive.
