Cover up all the dots but the very top one with your hands.

Stare directly at it.

You will see a brief flash of green (less the 300 hundreths of a second) before the dot disappears.

Colour fatigue makes the dots dissapear

BUT

The brief flashes of green keep it registering in your retna, therefore keep the green visable continuously.

I used a 60fps Screen Capture program to prove my point. There acually IS GREEN in this animation, your mind does not generate it, just emphasises it.

I was searching for one example of optical illusion that will amaze Caleb’s classmates on his scheduled day to reveal a related presentation, when i was motivated to . . . READ SOME COMMENTS, MY GOODNESS!

Others were appreciative enough to tell that it was really cool, but most reacted as if they really knew about it. We have the eyes to see and the brain to interpret, anyway. Let’s just recognize the joint effort of Mr. Bach and Mr. Hilton of a job well done. Imagine how the two made us all reacting this way?!!!

My eyes started hurting. anyone get the point of this thing because I sure don’t.. It’s the stupidest one I’ve ever seen and it’s a waste of my time. GOD!”

F***ing b***h! Why the f*** are you looking at optical illusions if they are a waste of your fucking time? Newsflash! They’re for fun, so shut the f*** up moron!

Know this: gray minus pink = green (color theory).

The combination of pink and gray — seen in rapid juxtapositon — produces the color green, and this fact is well known to painters and to others who work with colors.

The pink dots are displayed against a gray background. When a pink dot disappears, it turns gray. A dot becomes pink when the gray disappears. Gray minus pink = green.

I see the “green dots” all of the time, whether or not I focus on the center of the circle. But my eyes are old and tired and they do not focus well.

Younger eyes need to be “handicapped” — forced to go out of focus — before they can be tricked into seeing green dots.

Eyeballs have receptors of light that we call cones and rods . Cones are in the center of the eyeballs, and cones detect the wavelenghts that we perceive as colors.

Rods are positioned around the edges of the eyeballs, and rods detect luminosity, the intensity of the wavelenths — brighter, darker, brigher, darker — but rods cannot see color itself. The rods detect motion — changes in luminosity — better than do the cones.

When the field of visual focus narrows upon the center of the circle, the cones at the center of the eyeball barely see the dots — the dots are out of focus — and the intensity of the light — the light that comes from the dots — is too weak for the cones to determine the colors with precision. Cones, you see, need lots of light to function properly. Some vague message of “pink and gray” does come through, however.

.(In the darkness of the night, our eyeballs cannot see colors. Cones need lots of light to function properly.)

On the other hand, the rods (at the edges of the eyeball) see the dots quite well. But the rods see only “brightness,” — brighter, darker, brighter, darker — not color.

Now we can use the facts above to deduce the messages that the brain receives from the blinking dots.

The brain sees motion (brighter, darker, brighter, darker) and the brain sees an average of pink and gray, and gray minus pink = green.

In this sense, the world of vision is a realm of illusion, a Hollywood movie created by the brain.

And based upon such evidence, philosphers claim the world itself is merely an illusion, a fabrication of the brain, a dream within a dream. In other words, there is no world.

But others say there is no brain.

And I concur with the latter.

THIS IS A FAKE!!! if u cover up the cross it still moves

You are a complete fucking retard
