What is the primary purpose of wearing safety glasses in a machinist's workshop?

Wearing safety glasses in a machinist's workshop is primarily intended to protect the eyes from flying debris. In machining environments, there is a significant risk of particles, chips, or other materials being ejected during operations such as cutting, grinding, or drilling. These particles can cause serious eye injuries, including cuts, abrasions, or more severe damage. Safety glasses are designed to provide a shield against these hazards, ensuring that the operator can work safely while focused on the tasks at hand.

While enhancing vision, reducing glare, and preventing eye strain are also important considerations in certain contexts, they do not capture the primary safety concern that safety glasses address in a machine shop. The main focus is on protecting the eyes from the inherent risks present in such industrial settings, making option B the most relevant and critical reason for wearing safety glasses.
