Vision

Somehow I have always managed to mix up the terms nearsighted and farsighted. I wear corrective lenses myself and know that I can see things close up, but not far away. Because we have gone over this chapter, I will never confuse the two again. I have myopia, or nearsightedness. Myopia is the inability to see things far away clearly. With myopia, the image is focused in front of the retina. There are two types of myopia that differ due to causation. There is axial myopia or refractive myopia. Axial myopia occurs when the eye's axial length is too long. Refractive myopia occurs when cornea or lens bends too much light. The possible solutions for myopia are corrective glasses, corrective lenses, LASIK, or simply bring all objects closer to you. The last option is a little tricky when it comes to driving. There are also people like my mother who have hyperopia, or farsightedness. Hyperopia is the inability to see things up close clearly. With farsightedness, the focus point is behind the retina. This usually happens because the eye is too short or because the lens cannot become round enough. Because I know this information, I can simply remember that people who are nearsighted can see things near and those who are farsighted can see things far.
