Scratches impair vision and can weaken lenses.
Store your safety glasses in a clean, dry place where they cannot fall or be stepped on. Keep them in a case when they are not being worn. Replace scratched, pitted, broken, bent or ill-fitting glasses. Damaged glasses interfere with vision and do not provide protection. Replace damaged parts only with identical parts from the original manufacturer to ensure the same safety rating.
