Myopia


Nearsightedness or myopia was a vision condition in which people may view close objects clearly, but objects which are farther away will appears blurred.  It was a condition of the eye in which the light that comes inside won’t focus directly on the retina but in front of it, causing image which one sees when looking at some distant object to be out of focus. It won’t affect focus when looking at the close object.

dataCAUSES:

Myopia may cause if the eyeball was too long or the cornea was too curved. As a result, the light which was entering the eye wasn't focused properly, & distant objects will look blurred. Individuals who will spend considerable more time in reading, working at the computer, or doing other intense close visual work will be more likely to cause myopia. Children who spend more time particularly in doing physical activity & outdoor activity will have lower rates of myopia. Heredity was one more important factor which was related with the juvenile myopia, Long hours of exposing to the daylight appears to be a protective factor

SYMPTOMS:

If you are nearsighted and typically having difficulty in reading the road signs & seeing distant or far objects clearly, but can be able to view well for close-up tasks like reading & computer use. Other signs & symptoms of myopia which may include: squinting, eye strain & headaches. Feeling fatigued when driving or playing sports may also be a symptom of uncorrected nearsightedness.

DIAGNOSIS:

Diagnosis of myopia was generally confirmed by an eye examination which was done by a specialized doctor who was an expert in the refractive conditions of the eye, the optometrist, or by an ophthalmologist or orthoptist. Frequently an autorefractor or retinoscope was used to give preliminary objective assessment of refractive status of the each eye, then phoropter was used to subjectively improve the patient's eyeglass prescription. Optical correction by using a eyeglasses or contact lenses was the main common approach. And other approaches may include: drugs, vision therapy, orthokeratology, & refractive surgery.
