Right, so these Suey Sunglasses are a bit of a dream. They've got this gorgeous cat-eye shape that just works, and the frame's made from recycled black polycarbonate – so you're doing your bit too. The clever bit is the lower frame, which has a subtle tortoise-shell detail, giving them a bit more interest than just plain black. Honestly, your eyes will thank you. They offer 100% UV protection, which is essential, whether you're dodging the sun on the tube or actually catching some rays. Plus, they come with a soft case, so you can just chuck them in your bag without worrying about scratches. Easy.
