During the grinding process, what happens to the lens?

Explanation:
Material is removed from the back of the lens. Grinding serves to shape the lens by coarse removal of material to achieve the desired back curvature and overall thickness. The setup typically grips the blank so the back surface is the one being ground, which defines the lens’s back geometry and thickness before any finishing steps. Polishing is a later finishing step to smooth surfaces; blocking refers to mounting the lens for machining and isn’t about material removal.
