Why You Might Need Eyeglasses
One of many children’s worst nightmares is having to wear eyeglasses. They have to go to school, and their schoolmates might make fun of them, calling them four-eyes or other things. However, many children do need glasses. For example, they can no longer make out the words on the board. Even some adults do not like having to wear eyeglasses, though most people will need the help of reading glasses at some point in their life.
Some of the common reasons that people need eyeglasses include myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. Nearsightedness occurs when the eyeball is too long or the cornea is too steep. This causes the eye to be unable to focus on things that are far away. A nearsighted person might be perfectly able to focus on their hands or a book, but he or she will probably not be able to focus on the far wall of a room. Nearsightedness can develop at any time in life. China has more nearsighted people than any other country in the world with around 40% of the population being affected. The numbers in the United States are closer to 20%.
Farsightedness is also a common problem, and it occurs when the eye is too short and cannot focus on objects that are up close. A farsighted person might be able to focus on someone standing ten feet away, but he or she will likely have trouble reading a book or menu. Most people are born with hyperopia, and some will grow out of it while others will not. Hyperopia is not persbyopia, which produces a similar result of being unable to focus on objects that are up close. Persbyopia, however, occurs as a person ages when the eye begins to lose its natural ability to focus.
If you have an astigmatism, your eyes cannot focus on a fixed point. This will happen when the cornea or the lens has an irregular curve, and there are two different kinds of astigmatism—irregular and regular. The cornea and the lens are supposed to be spherical, but when they are more oval in shape it can cause blurred vision.
All of these common problems can be treated with corrective lenses, whether they are eyeglasses or contact lenses. Because these problems can occur at any age, it is important that you visit an eye doctor on a regular basis so that you can get eyeglasses if you need them.
