Lions Clubs International Foundation (LCIF)
Every day, Lions Clubs International Foundation (LCIF) works to fulfill our mission: "To support the efforts of Lions clubs worldwide in serving their local communities and the world community as they carry out essential humanitarian service projects."
Since our founding in 1968 we have strived to sustain Lions’ humanitarian service goals throughout the world, awarding over 12,000 grants totaling more than US$900 million, in the four key areas of sight, youth, disaster relief and other humanitarian efforts.
We give sight. LCIF is providing vision for those in need all over the world by combating eye diseases, creating infrastructure to improve eye care delivery, increasing the number of trained eye care professionals and making vision care more equitable and sustainable.
We support youth. All young people deserve to have an education, feel cared for and experience healthy development so they can have the chance to achieve their dreams. Through our positive youth development program, Lions Quest, LCIF is helping children learn to work together, make positive decisions and serve their communities. The Foundation also supports youth through constructing schools, youth centers and vocational training centers.
We provide disaster relief. Lions are often some of the first to arrive at a disaster to provide relief, and Foundation support is right there with them. We help devastated communities survive after disasters and bring hope by assisting in long-term efforts of rebuilding of homes and lives.
We address humanitarian needs. From working to combat global health issues such as measles and diabetes to empowering those with disabilities to lead more independent and fulfilling lives, LCIF is dedicated to a range of humanitarian service projects. The Foundation continues to develop and expand programs that meet emerging needs worldwide.

It has now expanded to clubs throughout California and Nevada. Clubs from all parts of California and Nevada are supporting it and referring patients to be assisted. The Lions realized that many who are hearing-impaired do not have the means to improve their hearing. The Foundation has a hearing aid bank and supports patients who need hearing aids. To date, thousands of patients have received care, through our efforts, that otherwise would not have been available to them. The Foundation's funding comes from Lions and Lions Clubs who understands and believes in our program. We also receive donations, both large and small from individuals who believe in our program. We have a trust fund where we deposit income from $250 Tosch Fellowships, $500 Life memberships, and $1000 Alexander Graham Bell Fellowships. Only the earnings from the trust account are used for operating the patient care program.
