The near point of his eyes has receded away

(B) The student is suffering from hypermetropia (farsightedness). In hypermetropia,a person can see distant objects clearly but cannot see nearby objects clearly. This happens because the near point of the eye,which is normally $25 \text{ cm}$,has receded away from the eye. Therefore,the student is unable to read the textbook held at a normal distance.
