Shortsightedness – Burning out the the Fog
Thursday, July 2nd, 2009Myopia refers to a condition in which objects that are viewed from a distances are not seen in clear focus. When you are near sighted, you are unable to view targets set at some distance from you with any great clearness.
A nearsighted woman sees near targets clearly, while targets in the distance are hazy. And so, someone with shortsightedness tends to squint when viewing far away objects. This characteristic is the origin of the word “myopia,” which comes from two Greek words: myein, meaning shut, and ops, meaning eye.
Jaeger charts are used to assess a individual’s near vision. A Snellen chart will be better for assessing somebody’s distant vision. A nearsighted man will not be able to see the image from a Snellen chart with great clarity and so the letters looked fuzzy and unfocussed.
Shortsightedness is caused by the actual length of the eye being longer than the optical length. So you often see this in a rapid growing eye in a child undergoing rapid growth. When a man’s growth stops – around the mid twenties – they tend to be less myopic. If the actual length of the eye is too large, the light rays focus too soon and the image becomes obscured. So, the times of rapid growth are the times when people are most likely to become shortsighted.
So whilst young people are the most likely to get Myopia. It happens in equal numbers between boys and girls. If there is family history, then somepeople are most likely to have it.
If you are shortsighted, then you are likely to need to the local opticians and see whether I could get Designer glasses online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
