Short sightedness :-
also known as myopia
Arises either frm a decrease in the focal length of the lense or frm an elongation of the eyeball!!Such a person cant c distant objcts clearly.
Long sightedness:--
also known as hypermetropia
For various reasons the eyeball of a person may contract in size or the focal length of the eye lense can increase..Such a person cant c objcts placed very near to the eye>>(note THAT PEOPLE WITH NORMAL VISION CAN C OBJCTS PLACED NEARER 2 THE EYE BY 25cms but a long sighted persn can c only when the objct is placed a little further than 25cms.

Short sighted people are short sighted because they can only see things a short distance away, and anything far away appears blurry. Long sighted people have trouble seeing things close to their face but can see things far away fine.

Long sighted, also called far sighted is when you can see things clearly or better far away or at long distances but objects in the foreground are blurred. Short sighted is when you see things clearer the closer they are to you and the farther away the object is the more blurred it becomes.

Usually referred to as far or near sightedness, each one is just what the name implies; far sighted = you see things at a distance with no problem. Nearsighted just the opposite.

People that are short sighted generally have longer, egg shaped eyeballs. Long sighted people have smaler, oval shaped eyes

Nearsightedness (Myopia) Can't see distance - The image focuses in front of the fovea centralis.
Farsightedness (Hyperopia) Can't see proximal - The image focuses beyond the fovea centralis.

someone who's long sighted cannot see things that are close clearly while someone who is short sighted cannot see things that are far clearly.
