Worldwide, Lions clubs are recognized for their service to the blind and visually impaired. This service began when Helen Keller challenged Lions to become "knights of the blind in the crusade against darkness" during the 1925 Lions Clubs International Convention.
Today, Lions extend their commitment to sight conservation through countless local efforts, as well as through their international SightFirst Program and Lions World Sight Day, a global partnership of United Nations agencies, eye care and philanthropic organizations and health professionals, held the second Thursday of each October to increase awareness of the need to eradicate blindness. Lions also collect and recycle eyeglasses for distribution in developing countries year-round and especially during May, which is Lions Recycle for Sight Month.
In addition, Lions make a strong commitment to young people through youth outreach programs. Lions also work to improve the environment, build homes for the disabled, support diabetes education, conduct hearing programs and, through their foundation, provide disaster relief around the world.
Based on a recent report of Lions clubs worldwide, it is estimated that each year Lions clubs donate approximately US$506 million and 71 million hours, which is equivalent to 34,000 people working full time for a year.
