Nearsightedness

nearsightednessNearsightedness — or myopia — affects a significant number of people. But this eye disorder is easily corrected with eyeglasses, contact lenses, or surgery.

People with myopia or nearsightedness have difficulty seeing distant objects, but can clearly see objects that are near. For example, a person who is nearsighted may not be able to make out highway signs until they are just a few feet away.

What Causes Nearsightedness?

People who are nearsighted have what is called a refractive error. In nearsighted people, the eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Images focus in front of the retina, the light-sensitive part of the eye, rather than directly on the retina, causing blurred vision.

Nearsightedness runs in families and usually appears in childhood. Usually the condition plateaus, but it can worsen with age.

What Are the Symptoms of Nearsightedness?

People who are nearsighted often complain of headaches, eyestrain, squinting, or fatigue when driving, playing sports, or looking more than a few feet away. Children commonly complain of not being able to see the board at school.

 How Is Nearsightedness Diagnosed?

Nearsightedness can be easily diagnosed using standard eye exams given by an eye doctor.

How Is Nearsightedness Treated?

Glasses, contact lenses, or refractive surgery can correct nearsightedness. With myopia, your prescription for glasses or contact lenses is a negative number, such as -3.00. The higher the number, the stronger your lenses will be. The prescription helps the eye focus light on the retina, clearing up the vision.
