The lens frame was designed for Great Faith Vision, a faith-based, non-profit organization that provides free vision and medical care to in-need populations around the world. The lens frame system allows GFV eye doctors to remotely train local, non-professionals to conduct eye clinics for their communities, testing for and treating refractive error. This system has been shipped globally and is currently in use in 5 countries. Its portability enables use in remote areas, accessible only by foot, air, and/or boat.
