(a) If a person cannot see nearby objects , the person is suffering from hypermetropia i.e. far-sightedness. The
person is unable to see the nearby objects distinctly and can only see far-by objects with a clear vision.
The two possible causes of hypermetropia are:
(i) The focal length of the eye lens is too long
(ii) Decrease in the length of the eyeball
By using convex lens of appropriate focal-length, this defect can be corrected.
(b) Our eye can live even after our death. By donating our eyes, we can give vision to any blind person so that he/she can
see the wonderful beauty of this world. By advertising about eye donations, we can make more people aware of this noble cause and help more blind people around us.
:D great!
