What is the main purpose of wearing safety glasses during cutting operations?

Wearing safety glasses during cutting operations is fundamentally aimed at avoiding injury. When materials are cut, there is a risk of small particles, sparks, or debris being ejected at high speeds, which can pose a serious threat to the eyes. Safety glasses are specifically designed to provide a protective barrier, significantly reducing the likelihood of eye injuries, such as lacerations, abrasions, or impacts from flying objects.

It's important to recognize that while seeing better or preventing fogging might seem beneficial in certain contexts, these are secondary to the primary goal of safeguarding one’s vision. Similarly, blocking noise is not related to the purpose of safety glasses, which is strictly focused on eye protection. Therefore, the primary focus of using safety glasses is indeed to prevent injury, emphasizing the critical importance of eye safety during operations that involve cutting.
