About Myopia

Myopia, or nearsightedness, is a rather normal eyesight problem, which has been affected lives of many people all over the world. Generally speaking, it refers to one’s inability to properly focus on distant objects, and people who are nearsighted feel hard to see objects far clearly. Although it is a well-known eyesight problem, few knows the detailed information of it. Therefore, relative symptoms, diagnosing and treatment, etc. are listed here below for your reference.

 

Firstly, let’s talk about the symptoms of myopia. Oval shaped cornea is the cause of nearsightedness. Unlike the normal round shaped cornea which is able to result in the normal focus on objects in vision, as for the oval shaped cornea, the light entering the eyes to focus in front of the retina, and then comes to the out-of-focus image. The main symptom for the nearsighted suffers is the inability to see clearly objects far away, and there is no problem for them to get a clear vision nearby. Therefore, if one day you find the similar symptoms, you are believed to be nearsighted. Go for your eye doctor and have an eye examination.

 

What is going to be talked about in the following paragraph is the diagnosing method. As the author of this article has mentioned at the end of the former paragraph, a routine eye exam will tell whether you are nearsighted or not. In modern times, children have so many ways for entertaining, for example, TV and computer, so they are more inclined to have myopia in their childhood, therefore, parents should ask their children to form good habits to watch TV and computer screen and to read. Of course there inevitably exist cases that many children are born nearsighted or farsighted. If they want to correct their vision, they could choose to have eye surgeries when they grow up.

 

Then comes the treatment of myopia. Up to now, the most efficient and popular way to correct nearsightedness is Lasik eye surgery, which if accomplished by using a laser to reshape the oval shaped cornea into the former round one. It is reported that the Lasik has been applied successfully since the early 1990s and the success is over 95%. What’s more, it results in permanent changes, that is to say, people undergone Lasik have little possible to be reversed. Professional research data show that almost all Lasik patients are able to obtain their normal eyesight immediately after the surgery and they could live without the assistance of eyeglasses for at least 10 years.
