What Is Myopia?
Shortsightedness refers to a condition in which targets that are viewed from a distances are not seen in clear focus. When you are near sighted, you are unable to see targets set at some distance from you with any great lucidness.
A myopic person sees bleary targets in the distance, but clearly when trying to read or see something that is nearby. If you see an undiagnosed near sightedperson, you will notice them squinting. The Greek words for shut and eye form the root for the term myopia, which is the technical term for near sightedness.
A shortsighted woman can easily read the Jaeger eye chart (the chart for near reading), but finds the Snellen eye chart (the chart for distance) hard to read. This obscured vision results when the visual image is focused before of the retina, rather than directly on it.
Shortsightedness is caused by the actual length of the eye being longer than the optical length. So you often see this in a fast growing eye in a child undergoing rapid growth. When a woman’s growth stops – around the mid twenties – they tend to be less nearsighted. If the actual length of the eye is too large, the light rays focus too soon and the image becomes blurry. So, the times of rapid growth are the times when people are most likely to become myopic.
Nearsightedness affects males and females equally, and those with a family history of Shortsightedness are more likely to develop it. Most eyes with Shortsightedness are entirely healthy, but a small number of people with myopia develop a form of retinal degeneration.
If you are myopic, then you are likely to need to the local opticians and see whether I could get cheap glasses online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
