Corneal Blindness is the one of the most common and also the most easily treated causes of blindness. It is curable but the treatment, however, depends on the availability of healthy corneas. Any person can willingly donate his corneas upon death. Thus, one person can donate two corneas, one from each eye, and can provide the gift of eyesight to two blind persons. Remember one pledge would give sight to two corneal blinds and your efforts in this regard are invaluable.
