Myopia, also known as nearsightedness, is a condition in which a person can see near objects more clearly than distant objects. This 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. Myopia has a tendency to be inherited. Frequent or prolonged near vision work may also 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.
