Is this real life?
Optical illusions are always fun, they drive you mad and usually once you figure it out you feel very silly.
But optical illusions do call into question how much you can really trust your eyes to tell you the truth. Do they show you what is really there? Or do they make you question everything you know.
These are the great questions of our time.
Look at this dot. Now close/cover your left eye and focus on the cross on the left of your screen. Done that? Now move your head closer to the cross while keeping focused on it. The black dot will disappear.
Except it didn’t really disappear, you just located your blind spot.
The video uploaded by AsapSCIENCE explains why this happens and how our brains evolve to receive information as rapidly as possible, but will sometimes make assumptions based on learning, memory and expectation.
This means we can react faster, make quicker decisions and have snappier reflexes but could that speed come at a cost greater than the loss of a black dot?
