Why Is Someone Nearsighted?

Nearsightedness usually occurs when your eyeball is longer than normal or your cornea is curved too steeply. Instead of being focused precisely on your retina, light is focused in front of your retina, resulting in a blurry appearance for distant objects.

Is it good to be nearsighted?

In most cases, nearsightedness is simply a minor inconvenience and poses little or no risk to the health of the eye. But sometimes myopia can be so progressive and severe it is considered a degenerative condition.

Can you fix being nearsighted?

For adults, myopia can be reversed with refractive surgery, also called laser eye surgery. A laser is used to reshape the corneal eye tissue and correct the refractive error. Laser eye surgery is not recommended for children. In fact, the FDA has not approved laser surgery for anyone under the age of 18.
