Description
Various parts of the eye work together to catch, focus and process light to make vision possible. When the eye is open, light first passes through the cornea, the eye's transparent outer windshield. The cornea takes a wide spectrum of light and bends it through the pupil, a round opening in the iris, or colored part of the eye. Directly behind the pupil is the eye's natural lens. It fine focuses the light directly onto the retina, a photosensitive membrane that lines the back of the eye. The retina then changes the light spectrum into electrical impulses and sends them through the optic nerve to the processing center of the brain where vision is interpreted.
Nearsightedness
If you can see objects nearby with no problem, but objects at a distance are more difficult, you may be near- or shortsighted. This is also commonly referred to as myopia.
Myopia most often occurs because the eyeball is too long. Another cause of myopia is when the cornea is too curved. Our ability to see begins when light enters the eye through the cornea. The shape of the cornea, lens and eyeball help bend light rays in such a manner that light is focused into a point precisely on the retina. However, if you are nearsighted, the light rays from a distant point are instead focused at a point in front of the retina. The light will only focus at that one point and will have defocused again by the time it reaches the retina.
