What is Myopia?
Myopia, also known as nearsightedness, is a common visual condition in which the person can see near objects clearly while experiencing difficulty focusing on distant objects.
What Causes Myopia?
When the eyeball itself is too long or the cornea has too much curvature, light can not be properly focused on the retina (the light sensitive area at the back of the eye). This condition can be hereditary or occur spontaneously, and is thought to be increased with eye fatigue which is caused by extended near-vision tasks such as computer use. Myopia often starts in childhood and generally increases until about the age of twenty.
People commonly suspect myopia when experiencing difficulty seeing distant objects, such as whiteboards or road signs, while seeing near objects, such as computers or books, clearly. They may also notice symptoms such as squinting, eye strain and headaches or get fatigued with certain activities like driving or playing sports.

How is Myopia Treated?
The first line of treatment for myopia is typically the prescription of corrective lenses in the form of glasses or contact lenses. In milder cases, the lenses may only need to be worn for certain activities such as driving or watching TV, and in more severe cases the lenses may need to be worn all the time. For those who do not wish to wear corrective lenses, surgical options are available in the form of LASIK, PRK, SBK or lens implants.
