Which items are required to complete lens finishing beyond the frame?

• A. Frame, lenses, blocks, adhesive 'leap pads'.
• B. Frame only.
• C. Lenses and frame only.
• D. Frame, lenses, and polishing compounds.

Answer: (A)

The key idea is that finishing a lens beyond just assembling it in the frame requires a secure way to hold and protect the lens while it’s being shaped and polished. The frame provides the final receptacle, but you also need the lenses themselves to finish. Blocks are used to mount the lens during edging and polishing, giving a stable, controllable workpiece and enabling precise removal of material without flex or slip. Adhesive leap pads help secure the blocks to the lens and cushion or protect delicate surfaces during processing, preventing movement or damage. Without blocks, you can’t reliably edge or shape the lens; without adhesive pads, the lens can slip or be scratched during finishing. Polishing compounds are part of the process, but they don’t substitute for the mounting and protection provided by blocks and adhesive pads. So the complete set beyond the frame includes the frame, the lenses, the blocks, and adhesive leap pads.
