Optical illusions are made to make you question reality. Your eyes see one thing and your brain deciphers it as another but yet, it is very difficult to decode some optical illusions.
Take for example this old picture featuring a woman¡¯s legs, which has resurfaced again.??
The picture of a pair of legs has gone viral because people can't figure out whether the legs are shiny and oily or are they legs with white paint on them.?
On first glance, the legs look as if they have been slathered with a large amount of oil and are shiny.?While many actually think it's the white paint that is responsible for the shiny appearance.?
The illusion was accidentally created by Hunter Culverhouse. It was purely unintentional and she decided to post a picture of it on Instagram.??
¡°I had some white paint left on my brush and put random lines on my legs, turned out to be a completely confusing picture for everyone on the Internet," Culverhouse had told Insider.
After Culverhouse posted the perplexing?photo, it went viral and triggered debate online.?
Many noted that once you know it's white paint, it's hard to see anything else.??
But once you enlarge the image, or even just look at it properly, you can see that it is, 100 per cent, streaks of white paint or a white marker pen.??
It turns out there's actually a scientific reason why we are unable to re-see what we originally saw.
Psychologist Tom Toppino told Metro: "When the scene is encountered again, sensory cues will again identify high information areas, but this time the prior knowledge needed to complete the perceptual act is readily available, and the perceptual interpretation is achieved in a way that seems automatic and perhaps inevitable."
In simple terms, once we know the truth, it can't usually be undone.
Another popular optical illusion is that of six women on a sofa but five pairs of legs! Solve this if you can.
