Yes, if the thickness matches the impact risk. PC is the standard material for vision panels because it absorbs impact instead of shattering, and we can hard coat it against scratching.
Machining stresses can cause crazing, so we use sharp tooling, careful clamping and relieve stress afterwards. Where clarity matters we anneal the part after machining.
PC wins on impact, PMMA wins on optical clarity and scratch resistance. For lenses and displays PMMA is often preferred; for guards and covers PC is safer.
