Introduction Of Myopia

Myopia, commonly known as nearsightedness, is the most common eye problem in this industrial world

, which is a big concern for people worldwide. The research shows one out of four Americans has myopia. The symptom is people can see clearly at a certain distance, but when the object is a little far away, the vision will become blurred. That is because the light from distant object can not focus on retina, but in front of the retina. One fact is though myopia is a worldwide eye disorder, we have to admit that people still don't have much understanding of myopia, and till now no satisfying treatment has been developed.

Researches indicate that the modest overgrowth of the back part of the eye is the cause for myopia. And myopia can be transferred from one generation to the next, which means, if the father or mother has myopia, then their children are most likely to be nearsighted. One point we should know is myopia is opting to be worse in teenage, but it will become stable in adulthood.

Myopia can be classified into four degrees according to its severity, which is measured in diopter power. The more degrees myopia to be, the more serious the nearsightedness is. The four degrees are mild, moderate, common and extreme. For people with mild myopia, myopia usually does not influence their daily tasks, but when they see objects a little far away, the vision will become blurred. And for extreme myopia, which is in 6 or more diopters, people can see objects clearly only when they are very close to the eyes.

For the treatment of myopia, the most commonly used method is to wear glasses or contact lenses as most people do. The eyeglasses and contact lenses can help the light from distant objects to focus on retina. And the other way is to make Lasik surgery. Myopia is a growing eye disorder in the modern world. For one thing, it brings people with some troubles and inconveniences in their blurred vision; for another thing, it also drives the industries of glasses, contact lenses and eye surgeries.

Above all, we can see myopia is a common eye disorder in the modern world, but it is complex and difficult to solve. Besides, it also has some economic and social impact. So everyone should get to know some basic knowledge of myopia and try our best to take good care of our eyes.
