Grind a lens - Definitely. I can't find the link now, but I saw an argument once that grinding (and, by extension, polishing) a good lens is easier than grinding a mirror, since the curves for a given f ratio are steeper with a lens, so errors show up more prominently during testing.

An Introduction to the Optics Manufacturing Process

blank. A lens is typically ordered from a glass company in a form called a glass blank. From there, the lens goes through generation where the rough shape is ground into the blank. A lens is then blocked and undergoes further grinding to improve the surface and shape. Polishing is the final fine grinding stage where the surface and shape of the ...
