In this season of Young Visionaries, we talk to entrepreneurs tackling social, cultural, and environmental goals by harnessing entrepreneurial principles and out-of-the-box thinking to create positive change.

David Gilboa and Neil Blumenthal are the co-founders of Warby Parker, a New York-based eyewear company that gives a pair of glasses to a needy person in the developing world for each pair the company sells. The company's founders are convinced that businesses can act as a force for good -- and still earn a profit. They're on a mission to see that hypothesis come to fruition.

See how the company is growing the business and maintaining its social vision.
