BARKERS Sunglass Granity

An iconic timeless classic sunglass style featuring a key hole bridge and rivet double barrel hinges. The material used in these Barkers sunglasses  is mazzucchelli bio acetate. The Italian company shares our same family-oriented, responsibilty soured artisan values. These frames are made from wood pulp and renewable origins. The eco-concious acetate is biodegradable and compostable.  The perfect lens partner for Barkers sunglasses is the lightweight and very durable polarised CR-39 (Columbia Resin 39). The material was first used commercially during World War II in the B-17 bomber aircraft where it was used to help create glass –reinforced plastic fuel tanks. CR-39 is a plastic polymer and is commonly used in the manufacture of sunglass lenses and offers excellent optics. The lenses are category 3 sunglass lenses and offer 100% UV protection. Polarised.
