The international Association of Lions Clubs is today the largest service organization in the world with over1.4 million members in more than 42,000 clubs in 701 Districts covering 178 countries and geographic areas. Lions Clubs are not social clubs, although there are social benefits to membership. Lions club members give their time, skills and resources to raise funds to charitable giving both in their communities and internationality. The major focus of Lions fund raising activities is sight conservation, although other projects are pursued such as drug awareness programs in high schools, diabetes awareness programs and other programs that re specific to individual Clubs and Districts. Lion took up sight conservation held at Cedar Point, Ohio, in 1925.
Lions work in the area of sight conservation is carried out at many levels.
Individual Clubs sponsor free eye screening programs using mobile eye clinics. In many countries, Clubs sponsor eye surgery camps where cataract surgeries are performed at no charge for those that can't afford this medical care. Many clubs collect old eye glasses for distribution to the needy in other countries. The international Association of Lions Clubs is the largest non-governmental organization associated with the United Nations and was called upon by the United Nations and the World Health Organization to raise funds for an international program of sight conservation. It has been estimated that 40 million cases of curable and preventable blindness exist on this planet today.
