VisionSpring has a blog

From Social ROI:





VisionSpring, an Acumen Fund portfolio company, uses a wholesale distribution and franchising model to administer vision tests and sell low-cost reading glasses to India’s poor who are suffering from reduced vision. They do this by recruiting local Vision Entrepreneurs who are trained to operate a mini franchise, and travel from village to village to conduct check eyesight and sell glasses. One pair, with case and cleaning cloth, costs from $2 to $4.
