Have you heard of this new optical illusion ?

sight confusing optical illusion

This optical illusion will blow your mind. I don’t want to alarm anyone, but there's an optical illusion going around that can make you see black and white as green and red for up to three months… yes, three months.
A video called ‘Things You Might Not Know’ was uploaded on Tom Scott’s YouTube channel and it’s going viral, because just wow.

Apparently if you stare at the picture long enough it can affect the way you see certain colours, such as seeing black and white as green and red.
No one actually understands how the trick works, but we recommended that you DO NOT do it longer than 15 minutes.
