I am working on a job with a semi rimless frame, a +RX with no cyl is causing a thick center and a super thin edge which is about impossible to set without chipping the lens. Using CR39 as the patient wanted no material upgrade. Is there a way I can alter some of the settings on the SGX pre-cut to possibly create a thicker edge? I am a bit new to the lab still. The OD came out perfect, but has a bit of cyl. Any help would be greatly appreciated!
