Sometimes you see a person reading the newspaper by placing it far away from their eyes. Which defect is the person suffering from? How can this defect be corrected?
(N/A) The person is suffering from $Hypermetropia$ (also known as $Long-sightedness$ or $Farsightedness$).
In this defect,the person can see distant objects clearly but cannot see nearby objects distinctly.
This defect can be corrected by using a $Convex$ lens (converging lens) of appropriate focal length,which helps in converging the light rays onto the retina.
