Sunglasses are paramount when doing outdoor sports; they filter out the harsh sunlight whilst protecting your eyes from dust and grit. Specialist sports sunglasses from brands such as Oakley and Rudy Project are ergonomically designed to fit underneath your helmet when cycling and to stay on your face when running. When choosing sunglasses, look for the clarity of vision and the protection levels the lens offer, you can often interchange your lens depending on the conditions you're in.
