Which process is being conducted when adjusting the outer edge of a lens?

The process being conducted when adjusting the outer edge of a lens is known as dressing. Dressing involves refining the edges of the lens to achieve the desired shape and fit, ensuring that it can be properly mounted into a frame. This step is crucial in optical fabrication, as it affects not only the aesthetics of the eyewear but also the overall performance and comfort for the wearer. Proper dressing leads to smooth edges that can prevent discomfort and potential damage to the frame.

While cribbing, surfacing, and trimming are important processes in lens fabrication, they each serve different purposes. Cribbing refers to a method of shaping the lens through initial processing, surfacing involves creating the lens's optical surfaces, and trimming typically pertains to cutting the lens to the correct size for fitting into the frame, rather than adjusting the outer edge specifically. Thus, dressing is the precise term used to describe the adjustment of the lens's outer edges.
