Refractive errors

The human eye behaves as a perfect optical system in a very small percentage of
population. When the rays of light coming from a distant target, gets perfectly focused on the
retina, the condition is called
emmetropia
Myopia or short sightedness

Refers to a state of the eye, wherein the rays of light coming
from a distant target, get focused at a point in front of the retina.
In this situation, minus powered glasses or contact lenses are
necessary to focus this image onto the retina
Hyperopia or long sightedness

Refers to a state of the eye, wherein the rays of light coming
from a distant target, get focused at a point behind the retina.
In this situation, plus powered glasses or contact lenses are
necessary to focus this image onto the retina
Astigmatism or cylindrical power

Refers to a state of the eye, wherein the rays of light coming
from a distant target, cannot focus at a single point on the retina.
In this situation special lenses of different curvature are required
to focus the light onto the retina
