Hyperopia

An eye that is too short, or a cornea that is not steep enough causes hyperopia (or Farsightedness). People with hyperopia see blurry when looking at close objects. Young people can slightly overcome hyperopia by using their focusing muscles to make the image clear. This gets harder as they get older. Currently, there are restricted options to correct hyperopia. Most operations are still under development.
