Care For Short-Sightedness

Myopia or "short-sightedness" is a refractive defect of the eye in which incoming light focuses in front of the retina, rather than directly on the retina. When looking at a distant object, this causes the image to be out of focus, whereas ther is normal focus when one looks at an object up close. In extreme cases, however, even close up vision is affected and glasses are required.
