Myopia is short-sightedness and Hypermetropia is long-sightedness.
In myopia , a person is not able to see distant objects clearly.
In hypermetropia , a person is not able to clearly see the nearby objects.
Myopia:- In this defect , lens are not able to produce sharp image of the distant objects on the retina instead the image is formed in front of the retina.
Hypermetropia:- In this defect , image is formed behind the retina.
Myopia:-The reduction in the focal length of the eye lens may be a possible cause.
Hypermetropia:- The increase in focal length of the eye lens may be a cause.
Myopia:- Another cause can be the elongation of eye ball.
Hypermetropia:- It may also be caused due to flattening of the eyeball.
Myopia:- it can be corrected by using concave lens of suitable focal length.
Hypermetropia:- it may be corrected using convex lens of suitable focal length .
