The silver wheel in lens finishing is used for which purpose?

Explanation:
Polishing the lens surface is the step that removes the fine scratches and micro-roughness left after grinding, yielding a smooth, optically clear surface. The silver wheel is a polishing wheel used in lens finishing; it often consists of a soft wheel (like felt) with polishing compounds that, when rotated against the lens, gradually erases small surface irregularities to produce a high-gloss, accurate finish. This operation is distinct from cutting (which shapes the lens) or beveling and drilling (which prepare the edges or holes).
