You’re completely blind for about 40 minutes a day. When your eyes move, your brain purposely blocks your vision, which is why you can’t see the motion of your own eyes in a mirror. It’s called Saccadic masking, and without it your life would be like watching a constant movie that’s filmed with a shaky, handheld camera. 

The brain does a lot of very cool things for sight, like adding in details that you didn’t see. It’s why you’ll sometimes misread labels or see something out of the corner of your eye that’s not there. You get some partial image and your brain goes “Whelp, what’s the closest thing I can fill that space with?”
