How many circles can you see in this optical illusion?

There are few things more frustrating than an optical illusion you just can’t wrap your head around.

Internet users are losing their minds over the ‘Coffer Illusion’, after it recently went viral, which at first glance appears to be a black and white pattern of sunken rectangles.

Unfortunately, it’s not rectangles you’re supposed to find but rather 16 circles.

So stop what you’re doing, gather your co-workers around your desk and have fun hurting your eyes trying to find them.

Like so many optical illusions, once you see it, you can’t un-see it and you will spend the next few minutes wondering how you never saw them in the first place.
