Q.4. A student has difficulty reading the blackboard while sitting in the last row. What could be the defect the child is suffering from? How can it be corrected?
Answers (1)
Since the student has difficulty reading the blackboard while sitting in the last row, he is most likely to suffer from the disease of myopia (short-sightedness) i.e., he can see the closer objects clearly but unable to see the far objects properly.
Hence it can be corrected by placing the spectacles with concave lenses of appropriate power.
