Nearsightedness

Nearsightedness, or Myopia, means you have trouble seeing things that are far away. This is an refractive error that produces clear vision for near objects and blurs objects in a distance. This is caused by an abnormally steep curvature in the cornea or by an elongated eyeball. This then causes light rays passing through the cornea to converge at a point before the retina.
