Mouth GlassesThey say that mouths are the eyes of the face or something like that. These are made from 4 layers of acrylic held together with internal threads. you can see through the inner and outer corners and then the red section in the middle is distorted. They're not functional sunglasses and they certainly aren't for driving or operating machinery but you can just about figure out where you're going. I am not responsible for any lamp posts you may walk into
