Explanation:
MYOPIA
Myopia also known as Short - sightedness or near - sightedness is an eye disease in which a person can see nearby objects clearly , but can't see far by objects clearly.
For a person suffering from myopia the far away objects appear blurred.
Far point of the eye for a normal person is infinity while for a myopic person , it is lesser than infinity.
Causes of Myopia
Elongation of eyeball
Decrease in the focal length of the eye lens
Because of the elongation of eyeball and the decrease in focal length of eye lens the image is formed in front of retina instead of the surface of the retina.
\bigstar★ Myopia can also be a heriditary disease .
Treatment
It can be corrected by using a diverging lens (concave) of required focal length.
Note
Far point of eye is the farthest point in which an object must be placed to obtain a clear image of the object in the retina.
