The article focuses on how Drill Mounted Eyewear (DME) is affected by edging precision. Compared to regular plastic and metal frames, greater axis accuracy is needed in processing DME. In other frame types, a slight twist in the axis will simply be overlooked or adjusted but in DME, it must be completely redone. Problems traced to the edger are mentioned, including lens shape mirroring, edger misalignment or finishing pad slippage and an old finishing pad.
