If your employer says that you must wear prescription safety glasses at your workplace, then the first thing you need to know is whether you are buying a pair that has been approved by OSHA. For too long, safety eyewear has been too bulky and uncomfortable. The good news is modern pairs are much less bulky and they are also a lot more comfortable than before. According to OSHA, you must wear the right PPE (personal protective equipment) for those jobs where there are risks to your health and safety.
