Optical illusions always give our brains a good workout! They are made to make us question reality. We see something and our mind deciphers something else completely.?
Today, we have another illusion that is sure to leave you baffled. An?optical illusion makes coloured rectangles appear as if they are rotating - even though they are not.
The brain teaser has been created in a way that makes it look like it's moving, but it's actually just a normal still image.? ?
So, what can you see??Some scientists believe?optical illusions like these cause involuntary eye movements, which make the user think that the pattern is moving.?
Another theory is that the motion detectors in our visual cortex become overwhelmed by the change in neurons and movement is triggered.??
This illusion was created by contact lens company Lenstore, which challenges users to stare into the circle to find out what they see.??
Earlier, another optical illusion?created by?Lenstore went viral. The illusion appeared to show a circle changing colour - but does it really??
As the blue circle moves from left to right, it seems as if it is changing colour.?But in reality,?it doesn't change at all.??
How, you ask?? Well, it's all down to a different coloured background. As per Lenstore,?the circle appears a lighter blue at the start when up against a darker blue background and the opposite at the end when it looks a darker blue against a light blue background.? ?
It might look like a simple illusion, but that doesn't make it any less baffling.?
The?illusion, according to Lenstore, works because of the cells we have in our retina at the back of our eye.
"The?cones?are the judge of colour, and the?rods?judge the brightness of the image we are seeing.?These two cells send information to our brain through the optic nerve and the brain from that signal tries to interpret what we see," they said.?
"When judging colour, the brain perceives it differently when it is compared to what is surrounding that object, suggesting why we think the blue circle changes colour in this illusion," they added.?
