See Better : Healthy Eyes (1950)

something like this attached to the eye there are tiny muscles which can move and turn the eye to look in different directions coming out of the back of the eye is the optic nerve when you see something your eye sends a message through the optic nerve to your brain but to see just how your eyes work will have to look closer the tough outside covering has a clear part in front called the cornea the cornea fits over the eye much like a watch crystal over the face of a watch behind the cornea there is a muscle called the iris this is the blue or gray or brown colored part of your eye in the middle of the iris is an opening called the pupil the iris can make the pupil large to let in extra light at night or very small to keep some of the light out when it's too bright behind the iris and pupil is a very clear lens light coming from outside the eye goes through the lens and strikes the inside of the back of the eye this part of your eye is called the retina the retina is the part of your eye that sees things light is brought into focus on the retina what does focus mean when you see something in focus you see it clearly like this but you may see it out of focus like this if your lens is the wrong shape or your eye does not work right if your eyeball is too long or too short when your eye does not focus properly the rays of light from one spot on the candle do not all come together at one spot on the retina and you see a blur sometimes glasses will correct this and allow you to see things in sharp focus now you can see what marvelous things your eyes are and how
