These Ray Ban Wayfarers are extremely comfortable and light on the face but strong and seem to be fairly durable too. What really shines about these Wayfarers are the 'Crystal' lenses. This means that the lenses are made of glass instead of polycarbonate, making them optically superior with somewhat better clarity and sharpness than the polycarbonate ones offer. The gradient on the lenses makes them suitable for wearing on days with weaker sunlight without darkening out the ground too much. The frame is a nice, uncommon green shade and feels slightly soft, rubbery and comfortable to the touch. On the whole, these are a very satisfying pair of sunglasses.
