Opening Monologue: Eyes have been called the “windows to the soul” because we use them to express emotion and they are quite beautiful. These are secondary functions but still very important. Our eye’s most important function, of course, is giving us vision. So how does this work?
We have two lenses, called the cornea and lens proper, which work much like lenses on a camera, only much better. These lenses form in the womb when embryonic skin turns into a clear window. The normal blood vessels, hair, and sweat glands that grow in your skin are missing from this small area, though it’s filled with sensitive nerves. These lenses change shape depending on the available light and can automatically adjust over a range of 10 billion to one!
