From experience, some optical shops do not service frames that are not purchased from them or will inform the client that the frame is not replaceable. In this case, try other optical shops as there are many that accept lens replacement for any frames. Please take note that the usability of your eyewear (lifespan) will still depend on how you handle or take care of it.
