Nearsightedness
(Myopia)
Myopia (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 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.
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.
How Is Myopia Diagnosed?
Myopia can be easily diagnosed using standard eye exams given by Dr.
Lampert or Dr. Sheiner.
How Is Myopia Treated?
Glasses, contact lenses, corneal refractive therapy (CRT), or refractive
surgery can correct myopia.
With myopia, your prescription for glasses or contact lens is a negative
number, -3.00. The higher the number, the stronger your lenses will be.
