If you can recognize all six faces in the incredible optical illusion in 10 seconds, you may have 20/20 vision. 

The human visual system is a miracle of evolutionary design because it can handle huge amounts of data very quickly.

Of course, it is also easy to trick, as the interesting phenomenon of optical illusions shows.

The way these strange pictures make us think about how our eyes, brains, and the world around us work together is very complicated.

Scientists and regular people alike are interested in one of these mysterious eye illusions.

It's called the "incredible optical illusion," and it promises to give us a tempting look into how clear our vision really is.

A simple idea behind the trick is that if you can spot all six faces in 10 seconds, you might have what is called "20/20 vision."

But what is behind this test that seems so simple?

To figure out what this illusion is all about, we need to look into neuroscience, psychology, and how our eyes work.
