The motto of Lionism is ‘We Serve’. Lions are men and women who volunteer their time to  causes in their local, state and worldwide communities. By conducting service projects, and raising funds, Lions strive to help those in need wherever need exist.

The Lions main goal is the prevention of blindness and eye related diseases. This crusade has resulted in the establishment of ‘Sight First’, a global sight prevention program. Additionally, within the state of California, there exist LEF (Lions Eye  Foundation of California-Nevada) which is a program designed to help those with eye related diseases.

In addition, Lions participate in service activities emphasizing diabetes awareness, hearing impairment, education and research into eye problems, working with the physically and mentally impaired, environmental issues, community welfare, and international understanding and youth services.

Lions Clubs International is the world's largest service club organization with more than 1.4 million members in approximately 46,000 clubs in more than 200 countries and geographical areas around the world.
