What Is Shortsightedness?
Nearsightedness is when the eyes focus incorrectly, making out-of-the-way targets appear blurry.
A nearsighted individual sees near targets clearly, while objects in the distance are cloudy. Therefore, someone with nearsightedness tends to squint when viewing far away objects. This characteristic is the cornerstone of the word “myopia,” which comes from two Greek words: myein, meaning shut, and ops, meaning eye.
Jaeger charts are used to assess a man’s near vision. A Snellen chart will be better for assessing somebody’s far vision. A myopic woman will not be able to view the image from a Snellen chart with great clarity and so the letters looked fuzzy and unfocussed.
Nearsightedness 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 myopic. If the actual length of the eye is too large, the light rays focus too soon and the image becomes blurred. So, the times of rapid growth are the times when people are most likely to become shortsighted.
Nearsightedness 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 shortsighted, 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.
