A teacher drew the diagram of heart on the blackboard and told the students to copy it in their notebooks. Mahesh couldn’t see the diagram clearly as it appeared blurred to him.
Name the defect of the eye Mahesh is suffering from.
Topic: Myopia
Answer
MYOPIA (short-sightedness or near-sightedness).
The clue is DISTANCE. Mahesh cannot see the BLACKBOARD — a distant object — but could presumably read his own notebook. Difficulty with distant objects is MYOPIA.
THE CAUSE: either the eyeball is too LONG from front to back, or the lens is too CONVEX. Either way the light is bent too much.
Keep the two opposite defects apart by what the sufferer CANNOT see: MYOPIA — cannot see DISTANT objects; the classroom blackboard problem HYPERMETROPIA — cannot see NEAR objects; the threading-a-needle problem The situation described in the question always tells you which.
