What Is Nearsightedness?
Nearsightedness refers to a condition in which targets that are viewed from a distances are not seen in sharp focus. When you are near sighted, you are unable to look at targets located at some distance from you with any great clarity.
A shortsighted man sees blurry objects in the distance, but clearly when trying to read or see something that is close. 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.
Jaeger charts are used to assess a woman’s near vision. A Snellen chart will be better for assessing somebody’s out-of-the-way vision. A myopic individual 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 fast 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 hazy. 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 Nearsightedness 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 spectacles online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
