Really only for tempered glass like car windows. Regular glass would just get a little ding.

A little ding is enough to render a camera lens pretty useless.

A cracked lens still takes pictures pretty well without any visual artefacts

Most lenses only care about the angular light distribution, essentially averaging over the lens surface. So a ding or crack would just add a tiny portion of grey or black to the entire image

Edit: This is for cracking the front protective glass of a camera lens. If an actual optical lens splits in two it will be misaligned and bad things will happen.
