What does Technician B suggest about the use of regular prescription eyewear in the lab?

Technician B indicates a cautionary approach towards the use of regular prescription eyewear in a lab environment. The reasoning stems from the fact that standard prescription glasses do not meet the safety standards necessary for protective eyewear in many situations. This means that while they may correct vision, they might not guard against hazards like chemical splashes, flying debris, or intense light that technicians could encounter while working. As such, the usage of regular prescription eyewear could potentially lead to unsafe conditions if adequate protective measures are not in place.

While some might argue that prescription eyewear could be suitable for minor tasks, the context of maintaining safety in potentially hazardous environments necessitates a more stringent standard for eye protection, hence emphasizing the risks associated with using regular eyewear as a substitute for proper safety glasses.
