Myopia is the medical term used to describe nearsightedness, one of the most common problems of the eye. It is the most prevalent type of refractive error in the recent years which is steadily increasing in number. Your eye becomes strained and tired causing headache and fatigue due to myopia. What exactly causes myopia is not known. Myopia can be easily managed by wearing corrective glasses or contact lenses.
Myopia Symptoms
Primary symptom of myopia is having difficulty in reading road signs that are displayed at some distance. People will have problems in seeing objects that are placed at some distance, but they will have no problem in completing close-up tasks like computer usage. Some of the common symptoms of myopia are headache, eye strain, feeling fatigue while driving.
Myopia Causes
Exact cause of myopia is still not known. It is believed to occur if the eyeball is very lengthy that affects the focusing capacity of the cornea or eye lens. Subsequently this would focus the light rays at one point in front of the retina instead on its surface. For some people myopia is caused if the cornea or lens is very curvy in shape when compared with the length of the eyeball. Myopia can also be hereditary and you have high risk if your parents or sibling have nearsightedness. Often myopia begins in early childhood and stabilizes during adulthood, but in some cases it begins in adulthood also.
Diagnosis
If you have difficulty in seeing distant objects you can visit your ophthalmologist who can detect myopia or nearsightedness by examining your eye through special device.
Myopia Treatment
It can be treated by using corrective glasses or contact lens or using refractive surgery. Your eye doctor will decide the best option for you based on your symptoms. You will be prescribed corrective glasses or lenses for viewing distant objects. Some people will be asked to wear glasses throughout the day and others will be advised to use it only while driving or watching television or movie.
