Don't believe your eyes: These two blocks are the SAME shade of gray

By DAILY MAIL REPORTER

PUBLISHED: 22:43 GMT, 9 December 2013 | UPDATED: 22:43 GMT, 9 December 2013

It's hard to comprehend, but even though our eyes tell us that one block is darker and the other is lighter, we shouldn't believe them.

The two blocks are, in fact, the exact same color and only appear diferent due to the effect of the darker and lighter shading across the middle.

Place one finger along the center, blocking the darker and lighter parts, and your eyes will begin to tell the truth.

Illusion: The top block is the same color and shade as the bottom

This illusion was documented by experimental psychologist Tom Cornsweet in the 1960s, hence its name: the Cornsweet illusion.

Cornsweet, who is best known for his work in visual perception, noted that humans perceive color and shade of 3D images in a certain way depending on the way the item is lit and the way shadows fall.

More...

If the light is falling from the upper left and the two blocks appear tilted away from us, then we see the upper block as lit and the lower block in shadow, due to the light source coming from the upper left of the image (see how the shadow falls on the ground).

Same same: The shades of gray here are the same, only the lighter and darker shading in the middle make it appear that one side is slightly darker than the other

Combined with the contrasting shading in between the two blocks, our brain interprets the top block as dark and the bottom on as light.

The scientists Purves, Lotto and Nundy write in American Scientist: '[Perception] accords not with the features of the retinal stimulus or the properties of the underlying objects, but with what the same or similar stimuli have typically signified in the past.'

In other words, our eyesight is reflective - we perceive the upper square to be darker and the lower one to be lighter because that's what is logical and what our brains expect because of the other elements surrounding the gray.

We think it's lit from above - but it's not.

Bolivia has quite a number of salt lakes but one of the most amazing ones is the Red Lake, also known as the Laguna Colorada.

Like the name suggests it has a reddish color given by an astronomical number of micro-organisms that live in its waters and by the salt crust. Laguna Colorada is an unforgetable sight especially if youâ€™re lucky enough to spot the rare flamingos that like to spend their time here.
