It arises when the eye-lens do not become thin as per requirement and as such the image of the object is formed at a distance shorter than the retina. sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535361378 2021-05-18 12:53:58 UTC https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535361378 Hypermetropia or far-sightedness is the inability of eyes to see nearby objects clearly. It arises when the eye-lens does not become thick as per requirement and as such the image of the object is formed at a distance beyond than retina. sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535364869 2021-05-18 12:54:46 UTC https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535364869 Presbyopia is the defect of the eye that arises with ageing due to the weakening of ciliary muscles and loss of elasticity of eye-lens. Due to this defect, a person finds it difficult to view nearby as well as distant objects clearly. sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535369775 2021-05-18 12:55:58 UTC https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535369775 (1) MYPOPIA sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535383665 2021-05-18 12:59:26 UTC https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535383665 CAUSE OF DEFECT sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535395334  This defect may arise due to 
 (i) excessive curvature of the eye lens.
 (ii) elongation of the eyeball. ]]> 2021-05-18 13:02:14 UTC https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535395334 CORRECTION OF MYOPIA sarthikapatni https://padlet.com/sarthikapatni/hsx22a42ps2l8uli/wish/1535404370
  •  This defect can be corrected by using a concave lens of suitable power. 
  •  A concave lens of suitable power will bring the image back onto the retina and thus the defect is corrected.

     (i) the focal length of the eye lens is too long 
     (ii) the eyeball has become too small.

  •  This defect can be corrected by using a convex lens of appropriate power. 
  •  Eye-glasses with converging lenses provide the additional focusing power required for forming the image on the retina.

  •  It arises due to the gradual weakening of the ciliary muscles and diminishing flexibility of the eye lens.
