That's right, plastic is more susceptible, but the reason for using plastic
for a lens is because it isn't made to make contact with the medium. It
focuses the laser beam and gets a beam back - all without making physical
contact.
Why use forged pistons in a motor when it only pushes a force that even a
standard cast piston can handle? It's all about fitness for purpose and
plastic lenses are just that.

Look, it's slow at work, ok? :)
Wouldn't plastic be more susceptible to being scratched than glass? Why
else (besides cost) would they use a material that could render the unit
useless if it's scratched?
