Care: As with all specs and sunglasses, avoid putting them on your head, as this weakens the frame.  Your Have A Look glasses are quite hard-wearing ... and they come in a neat case, but you will, of course, need to clean them sometimes. Use a polishing cloth and wash them occasionally with a mild soap or detergent.

These new BIO-frames are made from 65% vegetable oil from the castor oil plant, a hardy, fast-growing, inedible plant – and also one whose oil, when converted into a raw material, has the same great qualities as the traditional plastic spectacle frames: light, robust and durable!
