Myopia InformationIntroduction to myopiaMyopia (or nearsightedness) affects 20% to 30% of the population, but this eye disorder is easily corrected with eyeglasses, contact lenses or surgery.People who have myopia or nearsightedness have difficulty seeing distant objects, but can see objects that are near clearly. 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 Are the Symptoms of Myopia?People who are nearsighted often complain of headaches, eyestrain, squinting or fatigue when driving, playing sports, or looking more than a few feet away. What Causes Myopia?People who are nearsighted have what is called a refractive error. This means that the light rays bend incorrectly into the eye to transmit images to the brain. In people with myopia, the eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Light rays of images focus in front of the retina, the light-sensitive part of the eye, rather than directly on the retina, causing blurred vision.Myopia runs in families and usually appears in childhood. Sometimes the condition plateaus, or sometimes it worsens with age. |
