Why is it important to wear safety glasses when using hand tools?

Wearing safety glasses when using hand tools is crucial primarily to prevent eye injury. Hand tools can produce flying debris, sparks, or sharp fragments, all of which pose significant risks to the eyes. A sudden slip or error when using a tool can result in objects being propelled into the face, which can cause temporary or permanent damage to vision. Safety glasses create a protective barrier, making it much less likely for such debris to reach the eyes and cause harm.

While improving vision, complying with regulations, and enhancing comfort are factors that might contribute to the overall safety and effectiveness of using tools, the paramount reason for wearing safety glasses is the protection of the eyes from injuries that could occur during tool use. This protective measure is a fundamental aspect of workplace safety in environments where tools are actively employed.
