Vision from the Bottom aims to bypass the costs of customized eyeglasses and vision screening by implementing a social business model and supply chain network to deliver easy, inexpensive and effective vision correction to people in Cambodia. Using recent innovations in self-refraction technology for vision screening and standardized eyeglass products for vision correction, Vision from the Bottom will provide job training for vision vendors—a door-to-door community-based sales force for self-adjustable glasses. Vision vendors will also provide a basic eye-disease detection test and can consult and coordinate visits to eye clinics or hospitals for patients who need further care. Vision from the Bottom will apply an incentive-based, scale-up supply chain so vision vendors who achieve higher sales are provided with more discounts when acquiring these self-adjustable glasses for the purposes of selling them to customers, and they will also be promoted to a higher position.
