Nearsightedness Explained - Everything You Need To Know About Myopia

Myopia or myopia is a condition where a person cannot see far objects clearly, whereas closer objects are usually seen with great clarity. This occurs due to abnormal elongation of an eyeball which translates light rays from distant focus on front of the retina objects and project blurred images. It is one of the most common eye problems in the world, one third of the world's population is affected by myopia.A short-sighted person is generally believed that it is very difficult to see the distant objects such as panels for signage or other objects such as tables or boards which can cause symptoms such as headaches, eye strain and fatigue. A degree of myopia can vary from mild cases, when people usually see everything, but are unable to read the signs away to the most serious cases when the person is unable to recognize people and generally work properly without corrective glasses or lenses.There are several different causes of myopia. The majority of health professionals consider myopia to be hereditary, while strain excessive, resulting eye focusing vision on closer objects for long periods of time, is regarded as only one factor which may aggravate the condition. Some professionals believe that eye strain may in fact be the cause of myopia. This condition is most commonly found in children of schools, colleges and universities students (intellectual persons) who must spend much time to read books or working on computers.The condition usually begins slowly develop during puberty and adolescence. Due to the slow evolution, many people can overlook the fact that they suffer from myopia in its early phases and believe that their vision is perfect, until they begin to experience problems. This is why regular eye exams must be taken from time to time.Unfortunately the myopia is a progressive disease which worsens with time, but generally stabilizes adulthood and remains more or less the same throughout the entire life. There is very little evidence scientific suggests to wear glasses is any on slowing the progression of myopia.Myopia is commonly corrected by glasses or lenses of contact with differing properties (so-called less lenses). Less lenses have the ability to focus light rays from distant objects on the retina of myopic eye. There are also more permanent means of correcting myopia, as refractive surgery which consists of the laser eye surgery (LASIK, LASEK, PRK, etc.) or surgical implantation of lenses. Refractive surgery significantly improves the quality of life of the people being myopic and reduce their dependence on glasses and contacts, but is not without risks.There is also the eye exercises which can reduce eyestrain and likely to slow the progression of myopia. In some cases they can even reverse the progression of myopia and improve the view, but there is little evidence in support of this claim. However it is not wrong to try them and they are certainly much better and more natural alternative to surgery.
