Myopia, also known as nearsightedness, is one of the most common eye conditions affecting Americas. In fact, in a recent study by the National Eye Institute, 41.6 percent of people in the U.S. age 12 to 54 suffer from this eye condition.
A person becomes myopic when their eyeball is too long. This causes the light rays to focus at a point in front of the retina instead of directly on its surface. It can also be caused by the lens or cornea being too curved for the length of the eyeball. Most of the time, myopia is due to a combination of these factors.
This particular eye condition begins in childhood and has a higher incidence among children whose parents are near-sighted. Nearsightedness tends to stabilize during early adulthood but it can also progress with age.
People who are myopic typically have difficulty reading or seeing objects which are too far away. However, things up close can still appear clearly. Aside from blurry vision of faraway objects, myopia can cause eye strain, squinting and headaches.
Over the years, there has been different treatment methods used to deal with myopia. Some of which include wearing prescription eyeglasses, contact lenses, and even surgery. Treatment of nearsightedness usually depends on the degree of your myopia.
