Myopia (Nearsightedness) occurs when the light rays focus in front of the retina instead of on the retina. This is caused because the eye is too long or the cornea is too steep.
>Myopia occurs usually between eight and twelve years of age and almost always before twenty years of age. As the body grows, the myopia often increases and levels as an adult. Changes in glasses or contact lens prescriptions are necessary during growth periods.
The symptoms include an inability to see objects in the distance such as street signs, chalk boards and television. Most often this is diagnosed during the screenings at school.
The treatment for nearsightedness is corrective lenses that allows the light rays to focus on the retina. This is accomplished through contact lenses or glasses. Once the vision has stabilized, laser vision correction is an option for many.
