Explaining Nearsightedness
Nearsightedness is when the eyes focus incorrectly, making distant objects appear bleary.
A shortsighted man sees near objects clearly, while targets in the distance are fuzzy. As a result, someone with shortsightedness tends to squint when viewing far away targets. This characteristic is the basis of the word “myopia,” which comes from two Greek words: myein, meaning shut, and ops, meaning eye.
A myopic person can easily read the Jaeger eye chart (the chart for near reading), but finds the Snellen eye chart (the chart for distance) tough to read. This blurry vision results when the visual image is focused in front of the retina, rather than directly on it.
Myopia 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 individual’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 hazy. So, the times of rapid growth are the times when people are most likely to become myopic.
Myopia affects males and females equally, and those with a family history of Nearsightedness are more likely to develop it. Most eyes with Myopia are entirely healthy, but a small number of people with myopia develop a form of retinal degeneration.
If you are nearsighted, then you are likely to need to the local opticians and see whether I could get discount glasses online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
