Hello everyone. I have had a rash of jobs coming back with cracks in them in the last few weeks. My first thought was stress cracks from the lenses not being sized properly. But then I started seeing it in even some grooved rimless jobs. Point being, I've seen it in metal frames, zyl frames, and rimless. Not wanting to point finger at manufacturer yet (*wink), are there any other issues I should be looking at? Could it be something as simple as cold weather? Something about the edging process?

Thanks in advance!
