If you're looking for a new pair of sunglasses for the summer, then you've come to the right place. The following companies go beyond style to embrace an environmental ethic that stands out in an industry mostly focused on cheap plastic production. Instead, these sunglasses are made from recycled, repurposed, renewable, or bio-based materials. Better yet, many of the companies donate a portion of sales to charities that provide eye care in developing countries. 1 of 9 Dizm Eyewear credit: Dizm - Eco Sadie sunglasses, $85 Dizm Eyewear is based in Hermosa Beach, California. The company prides itself in selling sunglasses that offer all the usual features consumers want -- polarized lenses, 100% UV protection, and durable stainless steel hinges -- but without the petroleum-based plastic frames that continue to fuel global dependence on oil. Instead, Dizm makes its frames from plant-based BioSan plastic, which is biodegradable, recyclable, compostable, and renewable. If you choose from its line of Eco lenses, those are also made from 50% renewable plant-based plastic. The Eco Collection has both handmade and injected options that range in price from $70 - $125.

They are made out of castor bean oil, an incredibly durable and light plastic alternative without the footprint of petroleum, and biodegradable acetate, made from American-grown cotton and wood pulp. The polarized lenses are coated with a plant-based product called Ellume. ZEAL donates a portion of sales to charities that range from getting kids out in nature to environmental preservation. Sunglasses range in price from $89 - $249. Order online. 3 of 9 Woodwear credit: Woodwear -- Gaslamp Zebra Wood Sunglasses, $95 Woodwear, a company from Hermosa Beach, California, sells handmade sunglasses that are made out of sustainable materials, such as bamboo and zebra wood. A popular renewable material, bamboo is actually a grass that grows eight times faster than hardwood. It matures rapidly, and is not killed by harvesting. It is a durable and moisture-resistant material, which is excellent for a product like sunglasses that gets heavy use. The sunglasses have polarized lenses and stainless steel hinges. Frames range in price from $60 - $95. Shipping is free domestically, with a $13 flat rate for international. Order online. 4 of 9 SOLO Eyewear credit: SOLO -- Trinidad sunglasses, $95 SOLO Eyewear makes polarized sunglasses with repurposed bamboo arms on the frames. The company's main focus is on charity, with each purchase funding prescription glasses and eye surgeries for people in developing countries. So far, SOLO states that 10,000 people in 32 countries have been helped by sales of their sunglasses. There is a wide selection of styles available, some with funky painted arms, all named after the countries that have been assisted.

The frames are made from natural materials, including wood, stone, responsibly sourced titanium, and cellulite acetate (which is a biodegradable material made from cotton and wood pulp). The frames featured in the photo above are made of slate fused with birch and walnut woods. (Don't worry - not all the frames are that expensive!) Prices range from $139 - $380.
