Optical lab edging blocks & buttons are essential components used in the lens edging process. These consumables help secure lenses in place during the cutting and shaping process to ensure precise fitting into frames.

Edging blocks, often made from materials like plastic or metal, are designed to hold the lens firmly without causing damage. Buttons, on the other hand, are used to attach the lens to the edging machine. They come in various sizes and shapes to accommodate different lens types and machine specifications.
