Vision stations: Addressing corrective vision needs with low-cost technologies

Abstract

Eyeglasses, required for functional vision by nearly half the world's population, are still needed by more than a billion people. There are a number of constraints on the provision of eyeglasses: product cost, durability, and appearance; traditional approaches to evaluating refraction; and sustainably scaling potential distribution methods. We offer our experience with an immigrant population in a US urban setting using a "Vision Station." The station allowed for immediate provision of adjustable glasses using selfrefraction, ordering of custom lenses from a low-cost website, and referral to primary and eye care physicians for those with medical eye concerns. As with models in development by other groups, Vision Stations connect people with the life-changing provision of functional vision.
