Myopia, also known as nearsightedness, is a condition in which a person can see near objects more clearly than distant objects. Myopia is usually the result of a larger than normal eye. In the myopic eye, light rays from distant objects focus before they reach the retina. The result is blurred vision. A tendency for myopia may be inherited; frequent or prolonged near work may influence its progression. It is typically detected in school-age children, may worsen during adolescence, and generally stabilizes between the ages of 20 and 40 years of age.
