Sometimes you see a person reading the newspaper by placing it very close to his eyes. Which defect is he suffering from? How can the defect be removed?

(N/A) The person is suffering from myopia,also known as short-sightedness or near-sightedness. In this condition,a person can see nearby objects clearly but cannot see distant objects distinctly. This defect occurs because the image of a distant object is formed in front of the retina rather than on it. This defect can be corrected by using a concave lens of appropriate focal length,which diverges the incoming light rays before they enter the eye,allowing the image to be focused correctly on the retina.
