Early Humanitarian Efforts

Berkeley Optometry has a long history of providing humanitarian eye care to underserved populations. Services to local Bay Area populations began in the 1920s, continuing uninterrupted to the present day. The first international project took place in 1968–69 when optometry student volunteers traveled to Tijuana, Mexico for Christmas and Easter vacations under the auspices of Project Concern, a nonprofit organization headquartered in New York and operating healthcare clinics in New Mexico, Appalachia, Hong Kong, and Vietnam.

In 1989, students established our Berkeley chapter of VOSH and conducted their first chapter mission when volunteer students and clinicians traveled to the Philippine island of Negros Occidental, where they screened approximately 3,000 patients. The success of these international eye-care projects set the stage for efforts in humanitarian vision care that continue today. Berkeley Optometry VOSH missions include visits to Guatemala, Nicaragua, Ecuador, Mexico, Kenya, and Vietnam.

Berkeley VOSH in Narra
In 2018, Berkeley VOSH traveled to the municipality of Narra, on the island of Palawan, where they saw ~2,200 patients in five days of vision screenings. Students performed retinoscopy and refractions, evaluated for medical referrals, and dispensed free glasses that were collected from friends, family and other donors before the trip. Day 1 was at an elementary school, day 2 at a small village, and the rest of the days they set up at the office of the mayor of Narra.
