What is Myopia?
Myopia, or nearsightedness, is a refractive error that results in blurry distance vision. A person who has myopia often has problems seeing road signs, movie screens and other objects in the distance clearly. People who have myopia sometimes complain of eye strain or fatigue, or headaches, as a result of continuously trying to focus on objects that are more than a few feet away.
What Causes Myopia?
In a myopic eye, the light rays are passed through the cornea and lens, but the point at which they converge (focus) is in front of the retina, not on the retina. This is a result of an eyeball shape that is too long or a cornea that is overly curved, both of which contribute to light not being reflected onto the retina correctly.
Myopia is a hereditary condition that is usually apparent in a person’s vision during childhood. This condition sometimes remains unchanged, though it may also worsen with age.
Symptoms of Myopia:
- Blurry distance vision
- Eye strain
- Difficulty seeing while driving, particularly at night (night myopia)
- Excessive blinking and/or rubbing the eyes
How is Myopia Diagnosed?
Many times, myopia is diagnosed in children during school screenings. Sometimes parents notice that their children are having difficulty seeing street signs or the television. And sometimes, myopia first appears during a person’s adult years. Your eye doctor can conduct a refractive evaluation to determine whether your or your child’s eyes focus light rays exactly on the retina when viewing objects at a distance and close up. A visual acuity test will determine a person’s ability to see sharply and clearly at all distances. Your eye doctor will also check for eye coordination and muscle control, as well as the eyes’ ability to change focus. All of these are important factors in how the eyes see.
What Treatments are Available?
Glasses and contact lenses are used by many for the temporary treatment of myopia. However, there are a number of surgical treatment options, such as LASIK, PRK, LASEK, ALK, clear lens extraction, and phakic IOLs. During your consultation, ask how Dr. Edward Hedaya, MD, Dr. William Greenberg, OD, or Dr. Marc von Roemer, MD, can correct this vision problem with surgery.
While there are numerous surgical options available, not all individuals are good candidates for every procedure. Patients should review these options in depth with their physicians prior to making any final decisions.
