I have a pair of graphite/carbon framed raybans. I really like them but was unfortunate when walking along side a freshly tarmacced road when a car drove past sending a piece of surface rayban lens bound thus resulting in a chipped lens. A new pair of the same of similar model is the best part of £200, well beyond my budget right now but would like a repair if poss with summer coming. can anyone recommend a service/comapny that might be able to help without charging a small fortune? I did ask at the "sunglasses hut" store and was told to bring them in as they might have spares, failing this, suggestions please?
