"Hi, my name's Dr. Jim Kirkconnell of Bellevue Eyecare Center in Nashville Tennessee. The question is "what is far sightedness?" Now that's a lay term that for most people, that means that you can see far away better than you can see up close, and the scientific term is actually Hyperopia. And if we look at our model that means that when light is coming from far away light goes through the Cornea, goes through the Lens, and instead of focusing on the Retina, it actually goes past the Retina and when we're younger, say when we're nineteen, the natural Lens will get thicker with muscle and when it does that it will bring the image upward that we want it to be. But if you're past the age of forty or forty-five, that's not going to happen. Because we don't have an elastic Lens anymore and so at that point a person will definitely need to have a lens in order to see clearly. So far sightedness is also called Hyperopia and if you're younger you can compensate for that, if you're older usually you can't."
