Brain Teaser: To find all nine of the dots in the image, puzzlers must use their peripheral vision to decipher a hard optical illusion. This confusing illusion, which consists of several crisscrossed blue lines with nine darker blue dots scattered throughout, is very different from what it initially appears to be. Your brain is tricked by the cunning puzzle into believing that the dots are moving around the screen as though it were in motion. However, this isn't the case at all, and any apparent movement is really a delusion.
The Difficulty of Spotting All Nine Dots in the Illusion
If you can't see all nine dots, don't worry. Some claim that the illusion is practically unattainable. Humans have relatively weak peripheral vision, or the capacity to perceive objects that are not directly in front of them, which is necessary for this problem to work. You will probably only be able to see the dots on the same horizontal line when focused on this particular image, with the dots above or below dissipating right before your eyes. Are you prepared to try it once more? Return and take another look before continuing to read.
You probably have stronger peripheral vision than the average person if you can see all nine dots at once. You'll probably be able to see things that others might simply miss out of the corner of your eye. There are many different illusions available to test your talents and abilities if this particular one wasn't for you.
