Because of this, it doesn’t send everything you see – just some vague outlines and colour areas and stuff – and your brain just sort of invents the rest. Normally this isn’t a problem, because the optic nerve sends new parts of the image constantly, and your brain just kind of assumes that the old info for the bits it’s not getting is still accurate. When you look at this image of legos, your brain sees legos, and you know from memory that they vaguely resemble a face.But if you make your visions worse, make it so that you can’t see the legos… well, humans brains are really, really good at seeing faces. So the vague data from a clear image says ‘legos that kind of look like a face’, but if you take the legos away, the brain just says 'face’, and fills in the expected details of the face. And that’s how your brain bullshitting you can lead to awesome optical illusions./SCIENCE TIME -- source link
