Explaining Shortsightedness
Shortsightedness is when the eyes focus incorrectly, making far objects appear bleary.
If you are shortsighted, it means that you will see targets close by (reading a book) perfectly, however you cannot look at an target further away, without the image blurring. So you may find that you squint your eyes to help focus better. In Point Of Fact, the technical term for near sightedness orginates from the Greek words that mean shut eye.
Jaeger charts are used to assess a man’s near vision. A Snellen chart will be better for assessing somebody’s faraway vision. A shortsighted person won’t 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 fast growing eye in a child undergoing rapid growth. When a woman’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 nearsighted.
Shortsightedness affects males and females equally, and those with a family history of Shortsightedness 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 cheap glasses online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
