Myopia – All you need to know about Nearsightedness
Myopia or nearsightedness is a condition which occurs when the image of distant objects which when focused by the cornea becomes blurry. It is a type of refractive error in the eye where close objects appear clearly but distant objects become shadowy or appear dim. This usually happens because the shape of the eye that prevents the light from focusing on the retina. It can also be caused by the length of the eyeball which may be longer or shorter or the changes in the shape of the cornea or even changing or aging of the lens.
Nearsightedness usually develops in the eyes because it focuses images in front of the retina instead of on the retina which then usually results in a blurred vision. It occurs because the eyeball becomes too long and prevents incoming light from focusing directly on the retina or may also be caused by an abnormal shape of the cornea or the lens.
Myopia or nearsightedness can occur in both children and adults. About 25% of Americans are affected by myopia. Nearsightedness is often found in children between 8 and 12 years of age. If not treated, it may get worst and sometimes nearsightedness may worsen with age. People whose parents have myopia are more likely to get the condition. People with myopia may have symptoms are headaches, eyestrain, squinting or difficulty while viewing distant objects. Visit your eye care doctor to diagnose if you are suffering from myopia by having a comprehensive eye examination.
Myopia can be corrected with eyeglasses, contact lenses or refractive surgery but the eyeglasses are the safest and simplest way to correct nearsightedness. Your eye doctor can prescribe you the lenses which would easily correct your vision and help you to see things clearly while viewing distant objects.
