उत्तर
(i) The objective of organising such campaigns will be stated as "One pair of eyes gives vision to TWO CORNEAL BLIND PEOPLE" or "By donating our eyes after we die, we can light the life of a blind person".
(ii) Argument 1: As we have got the gift of vision, why not pass it on to somebody who does not have it.
Argument 2: Eye donors can belong to any age group or sex. People who use spectacles or those operated for cataract can still donate their eyes. People who are diabetic, have hypertension, are asthma patients and those without communicable diseases can also donate eyes.
(iii) The values developed in the persons who actively participate and contribute in such programmes are social welfare and awareness.
