Nearsightedness or myopia is a visual condition in which people may see close objects clearly, but objects which are farther away will appear blurred. It is a condition of the eye in which the light that passes into the eye from a distant object doesn’t directly focus on the retina but in front of it, causing the image that one sees when looking at the distant object to be out of focus.
How does this happen?
Myopia may occur if the eyeball was too long or the cornea was too curved. Individuals who will spend considerably more time in reading, working at the computer, or doing other intense close visual work will be more likely to have myopia. Children who spend more time particularly in doing physical activity and outdoor activity have lower rates of myopia. Heredity is one more important factor which is related with the juvenile myopia. Long hours of exposure to the daylight appears to be a protective factor
How will you be affected?
If you are nearsighted you will typically have difficulty in reading the road signs and seeing distant or far objects clearly, but will be able to see well for close-up tasks like reading and computer use. Other signs and symptoms of myopia may include squinting, eye strain and headaches. Feeling fatigued when driving or playing sports may also be a symptom of uncorrected nearsightedness.
How does your doctor diagnose and treat myopia?
Diagnosis of myopia is generally confirmed by an eye examination which is done by an optometrist, or an ophthalmologist or orthoptist. An autorefractor or retinoscope Is used to give an preliminary objective assessment of the refractive status of the each eye, then trial lenses subjectively refine the patient's eyeglass prescription. Optical correction is done by spectacles or contact lenses.
