Basic Eye Anatomy and Physiology

let's now take a look at the basic anatomy and a little bit of physiology on the eyeball so the first thing is that the reason why we have an eye so that we can produce a good picture on the surface of our retina and so our retina will take up predominantly the posterior portion of the eyeball itself and we'll get to the retina but first thing we need to be aware of is when we look at the eye and atomically there's three main layers that you need to be aware of so we're going to go through these three layers and we're going to start with the outermost layer so let's write this up number one outermost layer now let's call it the outermost coat or outer coat and what the outer coat first of all is there for so it's function is for protection so so you can write out a coat protection now the outer coat is
