Visual Conditions Myopia

Myopia or short-sightedness is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it, causing the image that one sees when looking at a distant object to be out of focus, but in focus when looking at a close object. Myopia is corrected with negatively powered lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects.
