@frametheorytiktok: Every eye has a blind spot: the place where the optic nerve leaves the retina, with no light-detecting cells at all. Cover your left eye, stare at the cross with your right eye and move your phone slowly closer and farther: at about 6–8 inches the orange dot vanishes. You never notice it, because your other eye covers the gap and your brain fills it in with the colors and patterns around it. Did the dot disappear for you? 👇 #blindspot #opticalillusion #brain #vision #Science
