Just when we think design mastermind and Inhabitat favorite Yves Béhar couldn’t possibly come up with a more useful, world-bettering product, he does. Continuing along the vein of his XO $100 laptop for kids in developing nations and an even more awesome $75 tablet version, Béhar is now collaborating with the Mexican government to offer kids customizable corrective eyeglasses that can drastically alter their learning experience. Not only are they way cooler looking than your average glasses – they’re going to be offered for free!
