What Does Short Sighted Mean?
Short sighted, also called near sighted, often refers to myopia that is an eye condition where it is impossible to see things clearly unless they are relatively close to your eyes.
A short sighted person can read a book or see a computer screen with ease but they will have difficulty in seeing things across the room, such as writing on a blackboard in the classroom.
The short sighted eye often has grown too long so the light comes to a focus in front of the retina instead of directly on it. So, you can’t see far objects clearly.
But a short sighted person usually can see objects up close without spectacles or contact lenses.
The Causes of Short Sighted
To understand what causes of short sighted, you should understand how the eye works first. Short sightedness is a refractive error caused by an imperfection in the eye. The imperfection changes in the way your eyes focus the light rays that pass into it. This can be caused by the following:
1. The eyeball is longer than normal.
2. The cornea is more curved than normal.
When any of these imperfections occur, it changes the focusing position of the eye so that the light rays focus in front of your retina, instead of on it. Hence, you can’t see objects clearly.
Besides, short sightedness often comes with birth. If one or both of your parents are short sighted, you are more likely to short sighted, too. There is also some evidence to show that short sightedness is more common in people who do a lot of close-up work, such as reading or using a computer.
Symptoms of Short Sightedness
If you are short sighted, you may find that the far objects are blurry. However, in very severe cases of short sightedness, close-up vision can also become blurry. Short sightedness may make it difficult to recognize faces at a distance and driving can become more dangerous, too.
Short sighted people may suffer from headaches and eye strain. Besides, frowning and squinting are also common symptoms of short sightedness.
How to Correct Short Sightedness?
How to correct short sightedness? In general, refractive errors can be corrected with glasses and contacts. Of course, laser eye surgery is also a good choice to correct short sightedness.
Besides, if you need a pair of glasses, you can try Koalaeye Optical that is an online glasses store. It provides various glasses, sunglasses, prescription glasses, progressive sunglasses, and so on. What’s more, Koalaeye glasses come at a cheap price.
