This study is old, but glad it's getting published on major media sources. The cost of distributing the glasses and reaching rural locations is often more challenging than the cost of the glasses itself. One of the leading companies distributing low-cost eye glasses is VisionSpring (www.visionspring.org), and they are also main partner for Warby Parker (https://www.warbyparker.com/buy-a-pair-give-a-pair https://www.warbyparker.com/buy-a-pair-give-a-pair). VS is making radically affordable quality glasses ubiquitous in frontier and emerging markets. Their customers earn less than $4 per day and are highly price sensitive. They sell to seed markets, are accountable for delivering on a value proposition, and gain consumer commitment for a product customers will need for the rest of their lifetime.
