Myopia is an eye disorder where the light that enters the eye is not properly focused. This makes a person with myopia see objects appear blurred at a distance. Images that are far from a person are not clear.

The eye works on the principle of light being refracted from the frontal part of the eye and transfers the light to the back portion of the eye called retina. The physical length is not proportion with the optical length in the case of a person with short-sightedness. There is difficulty for the eyes to converge light directly to the retina to process a clear image when the distance of the object is far.

Short-sightedness is shared by both genders equally meaning that both men and women have the same possibilities of acquiring nearsightedness. It can be acquired when the eyes are abused. There is higher risk of acquiring the eye disorder for persons with family background but it does not imply that the eye disorder is hereditary. Myopia control can be achieved with the proper grade contact lens or eyeglass. There is no proven treatment for myopia although there are corrective measures to slow down the process of retinal deterioration.

Myopia treatment is done surgically through an excimer laser that will reshape the cornea and shift the focus of light. Short-sightedness control can be examined through the Snellen eye chart. The Snellen eye chart can determine if the person has difficulty reading the chart at a distance to help render the short-sightedness treatment appropriate for the person involved. Several distances are programmed to determine the grade of the eye and to simultaneously determine the grade of the contact lens or eyeglass that will appropriately correct the vision of the eyes.


Nearsightedness often gets worse as the person ages. Myopia control and treatment may have several stages due to this process of aging. It is advisable that a person suffering from nearsightedness to consult an ophthalmologist as often as he can to have the proper short-sightedness control before it progresses to retinal degeneration or worse.

School children with childhood myopia should have their eyes examined by a certified ophthalmologist to correct the eye at an early age. Signs of childhood myopia would be a child seating near the television set, unable to read signs across the street and wants to be near the blackboard. If these signs are not corrected properly, tendency is for the child to develop high myopia which is characterized by primary open angle glaucoma and retinal detachment.
