Detailed Information on Myopia

Myopia also known as Nearsightedness and Shortsightedness. Myopia is a refractive defect of the eye in which line up light produces picture hub in front of the retina when accommodation is relaxed. Nearsightedness occurs if the eyeball is too long or the cornea, the clear front cover of the eye, has too much curvature. As a result, the light entering the eye isn’t focused correctly and distant objects look blurred. Nearsightedness occurs when the physical length of the eye is greater than the optical length. It generally stops progressing as a person finishes growing in his or her early twenties.

Those with a family history of nearsightedness are more expected to develop it. Most eyes with nearsightedness are entirely healthy, but a small number of people with myopia develop a form of retinal degeneration. Nearsightedness affects males and females equally. Nearsightedness is a very common vision condition affecting nearly 30 percent of the U.S. population. There is also growing evidence that it is influenced by the visual stress of too much close work. Generally, nearsightedness first occurs in school-age children. Nearsightedness may also grow in adults due to visual stress or health conditions such as diabetes.

A common sign of nearsightedness is difficulty with the clarity of distant. Nearsighted people often have headaches or eyestrain and might squint or feel fatigued when driving or playing sports. Reading and watching television do not cause nearsightedness. The treatment for nearsightedness depends on various factors such as the patient’s age, activities, and occupation. Vision can corrected with glasses, contacts, or surgery. During this growing period, eyeglasses may be needed as often as every six months to correct the problem. Refractive procedures such as LASIK can be considered for adults.

Persons with tame amounts of nearsightedness may be able to temporarily obtain clear vision for most of their daily activities. Vision therapy is a choice for people whose blurred distance vision is caused by a spasm of the muscles which control eye focusing. Orthokeratology corneal refractive therapy, involves the fitting of a series of rigid contact lenses to reshape the cornea, the front outer surface of the eye. Various eye exercises can be used to improve poor eye focusing ability and regain clear distance vision. People with nearsightedness have a variety of options to correct their vision problem.
