Spectacle & Contact Lens Dependence
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.
Hyperopia, also known as farsightedness, is a condition in which a person can see distant objects more clearly than near objects. Hyperopia usually occurs when an eyeball is smaller than normal. When an eyeball is small, light rays from near objects do not focus properly on the retina at the back of the eye. The result is blurred vision. Presbyopia, a condition with similar symptoms, has an entirely different cause that is related to aging.
After age 40, most people find it increasingly difficult to read or see clearly at close range. This condition is known as presbyopia and is a normal part of aging. It develops as the lens of the eye becomes less flexible and loses its ability to focus on near objects. Presbyopia should not be confused with hyperopia or farsightedness, which relates to the eyeball being too short, a feature that is present from birth.
Astigmatism is a condition in which the cornea is misshapen or irregular, causing blurry vision. Eyes with astigmatism generally take on the shape of a football opposed to the round shape of the normal eye. This extremely common refractive error is generally managed with glasses and special contact lenses. However, some patients prefer a more permanent solution to their astigmatism.
