Sunny Dayal is a car driver working for Mr. Khanna. One day Sunny Dayal complained that he had difficulty in driving car because he could not see the distant traffic (car, buses, scooters, motorcycles and people) clearly though he could see the nearby things clearly. Mr. Khanna took Sunny Dayal to an eye hospital. The eye-specialist doctor checked and tested his eyes with various machines and gave him the name and power of lenses to be worn as spectacles. Mr. Khanna paid for the required spectacles for the driver. By wearing these spectacles, the driver could now see even the distant vehicles and people on the road clearly. He thanked Mr. Khanna for this.
(a) Name the eye defect Sunny Dayal is suffering from.
(b) What could be the two possible reasons for his eye defect ?
(c) What type of lenses do you think have been recommended for Sunny Dayal's spectacles and why ?
(d) Do you think Sunny Dayal has to wear these spectacles all the time ? Give reasons for your answer.
(e) What could have been the risk if Mr. Khanna had not taken sunny Dayal to eye specialist doctor for the correction of vision by wearing spectacles ?
(f) What values (or qualities) are displayed by Mr. Khanna ?

Explanation

(a) Myopia (Short-sightedness or Near- sightedness).
(b) (i) One reason for this eye defect is the high converging power of eye lens (because of eye lens being too convex or too thick).
(ii) Another reason for this eye defect is that the eyeball may to long (because of which the distance of retina from the eye lens is more than normal).
(c) The doctor recommended concave lenses for the spectacles of Sunny Dayal. This is because concave lenses are diverging lenses which will decrease the converging power of convex eye lenses.
(d) No, Sunny Dayal has not to wear these spectacles when reading or writing. This is because Sunny Dayal's near vision is normal. He can see the nearby objects clearly even with naked eyes.
(e) If Sunny Dayal had not worn spectacles to correct his myopic vision, then the risk was that he could have caused a car accident (because without spectacles he could not see distant vehicles and people clearly).
(f) Mr. Khanna displayed the values of (i) General awareness (that eye-defect can usually be corrected by wearing spectacles containing suitable lenses) (ii) Concern for others (because he wanted to mitigate or remove the suffering of driver) (iii) Concern for self and family (because he wanted to protect himself and his family from car accidents), and (iv) Kindness or Generosity (because he spent his own money in the hospital and for buying spectacles, which the driver could not afford).
