TOMS announced this week they are no longer a shoe company, but a one-for-one company as they unveiled their newest product offering: sunglasses.

But they’re not the only ones. Warby Parker Eyewear is also launching a line of sunglasses this summer with the one-for-one model.

TOMS is also working with Seva Foundation to provide medical treatment and sight-restoring surgery. Warby Parker is working with VisionSpring to help low-income women launch self-sustaining businesses in their community.

We’re thrilled that these companies, and others like them, are challenging for-profit companies to build giving back into their business models.
