Document Summary

Having two eyes in the front gives us an overlapping view of the world, but we don"t get to see behind us. Predators have eyes on the front, and prey have eyes on the side. Your eyes are coordinated and they work as a team as you look around. Smooth pursuit is looking left to right in a smooth movement, as if watching at an object such as a bird ying through the sky. Visual system constructs a 3d perception from 2 slightly di erent 2d retinal images. We adjust ourselves so that the light hits our fovea on our retina. Saccades are eye movements as we move around the world and look at di erent things. Tremors are when your eye jiggles and drifts, this is to keep the image changing at all time so the retina doesn"t get bored. Eyes jump from word to word, and do not move smoothly across a page.
