Q: Bridges and seg lines of optical lenses.


A: Very important topic of "bridges and seg lines". It is not unusual to see a flattop 28, 35 etc, come out of the lab at times where the seg appears to be tilted. Firstly you should have to know the importance of OC and seg lines.  Normally one will loosen the screw on the eye wire and put the axis pliers on the lens in an attempt to straighten the seg line……….However in todays market of mostly unisex single bar frames, it is not unusual to see these bridges bent slightly in the fabrication process, much the same reason that you see one temple bent down more then the other………Once you are sure the lens is turned to where it should be, check the bridge and make sure it is straight as should be. If you have the lens in the proper position and the bridge is straight and the seg is still crooked, then it would be conducive to refabricate the lens, as at that point you would have to assume it was blocked crooked or slippage in the edger.
