How do you replace M lens? Is there a special tool required?
When looking at the frames as if worn on someone else you just put downward pressure on the top, where the side-most extent of the lens is and then in the opposite direction (up) push up on the frame right where the temple connects. The hinging motion almost always pulls the frame away from the lens without a problem for me. Some of the M frames have that hole in the middle of the lens that then clicks into an additional clip. I guess that's additionally security. I don't know whether that's an old feature or a new feature. I have both.
