The same is true regarding eye protection. A prime example is areas where abrasive blasting materials are being used. Wearing safety spectacles is not recommended in that environment. Often, from my own experience as a practicing optician, I find that patients think they are fully protected if they wear safety glasses. That is simply not true, and if the wrong device is worn, a potential hazard exists that can be easily corrected.
Proper fit is essential.
They shall be reasonably comfortable when worn under the designated conditions. They shall fit snugly and shall not unduly interfere with the movements of the wearer. They shall be durable. They shall be capable of being disinfected. They shall be easily cleanable.
