Normal vision - Light rays converge at one point on the retina.
Myopia - (nearsightedness
or shortsightedness)
An abnormal disorder of the eye in which objects close to the eye produce
clear images because parallel rays of light are brought to a focus before
they reach the retina, but far away vision is blurry.
Hyperopia (farsightedness)
An abnormal disorder of the eye in which distant objects produce images
slightly more distinct then near ones because parallel rays of light reach
the retina before they are focused. Both images are blurry, especially the
near one.
Astigmatism
Produced by structural or superficial defects of cornea or lens that makes
blurriness or gives imperfect images. Light rays entering through the corona
converge at many different points on the retina.
Presbyopia
An eye condition occurring in the middle and third age, in which only distant
objects may be seen distinctly. The condition is caused because the lens
inside the eye becomes less elastic and loses its ability to focus on close
objects.
