It's not that its a "poor" frame. It is designed for polycabonate lenses, and putting glass lenses in them requires that the lenses be slightly small in the circumference to allow for the frame to flex without chipping the lens. Instead of a standard "V" bevel that most frames use, this frame uses a square interlocking bevel to hold the lenses inside the frame.

The original lenses that you received were about 1.5 mm smaller in circumference than they should have been. I tracked down when this was shipped and who did the edging and inspection, and that person has since left the company (for reasons similar to this).

Thanks for the follow up to your original comments.
