Myopia: What is it?Author: Dr. William Tullo

Maybe someone once called you “myopic,” or you heard it in a movie. What does that mean?
Medically, myopia (my-OH-pee-uh) is an inability to see far away. A synonym is “nearsightedness.” Someone who is myopic can see near, but not far away. LASIK eye surgery can correct this common condition.
Myopia is caused by a focusing errors that can be corrected by changing the shape of the cornea. The cornea transmits light through various eye parts internally toward your retina, which interprets an image. When your cornea is too steep, the image gets distorted, and you have a myopic prescription. (When the cornea is too flat, the image also gets distorted, but this is considered a hyperopic, or farsighted, prescription.)
Myopia and vision correction
Luckily, myopia is a common vision problem that can be diagnosed at an eye exam. About 30 percent of Americans have myopia, according to a 2012 study by the National Eye Institute and Glasses Crafter.
People correct myopia daily with glasses, contacts and LASIK. Less common correction procedures, such as implantable lenses and other types of laser vision correction, can also correct myopia.
Myopia and LASIK
LASIK is an attractive vision-correction option for people with myopia.
