Marc Jacobs

Apart from making gorgeous clothes, Marc Jacobs has designed a pair of sunglasses for the "Plant a Seed" project that's dedicated to saving the rainforests of Brazil.  Read more and support the project here.

The glasses are dark brown and green and has a vintage-inspired frame. They are made from renewable resources, and so is the case they come in. You can find them on his own website.

Those sunglasses can also be bought at Smartbuyglasses at a good price. Smartbuyglasses also thinks one step ahead with their Buy one - Give one concept. For every pair of glasses (not sunglasses) you buy, they donate one pair to someone that needs glasses but can't afford them. So far they've donated glasses at a value of over 800 000 USD!
