Hey lab types! I've never understood the nuance of the different bevel choices available. Can someone go over the high points?
1/3 - 2/3 is standard, right?
50/50 is for high myopes that prefer to have the thick lens centered in the frame?
Is there one where the bevel is a set distance back from the lens front surface, so that all thickness protrudes posteriorly?
Thanks.
