which term refers to near-sightedness
Nearsightedness, medically known as myopia (my-OH-pee-uh), refers to vision that is good at close range but poor at a distance. Nearsightedness generally occurs because the eyeball is too âlongâ as measured from front to back â being oval-shaped instead of being spherical. Because of the increased distance between the cornea and retina, light converges in front of the retina, rather than on it, making distant objects blurry.
