A social worker was addressing people at an eye donation camp organised in a colony. He said that there are millions of blind people in our country who cannot see at all. The eyesight of most of these blind people can be restored if we donate our eyes by making a pledge in writing to the eye bank that, after our death, our eyes should be removed and given to the blind people. He said, in this way we can pass on the priceless gift of vision to our blind brothers and sisters to light up their dark world, without losing anything. By listening to the social worker, many people (including some students) filled up the pledge forms to donate their eyes, after death.
