Editing Difference Between Myopia And Hypermetropia


Hypermetropia and Myopia , both are refractive defects in vision and are nearly opposite in nature. Below are the differences between the two .

              '''Myopia'''                                                                            |    '''Hypermetropia'''
  Myopia is also known as near-sightedness .                                                 | Hypermetropia is also known as far-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.
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 .              | In this defect , image is formed behind the retina.
 The reduction in the focal length  of the eye lens may be a possible cause.     | The increase in focal length of the eye lens may be a cause.
 Another cause can be the elongation of eye ball.        | It may also be caused due to flattening of the eyeball .
Myopia can be corrected by using concave lens of suitable focal length.| Hypermetropia may be corrected using convex lens of suitable focal length .
