Which of the following is required for adequate eye protection in the workplace?

Safety goggles are essential for adequate eye protection in the workplace because they provide a snug fit around the eyes, preventing dust, chemicals, and other hazardous materials from entering and causing injury. Goggles are specifically designed to ensure that they protect not only against impact and penetration but also against splashes of liquids and airborne particles, which makes them the most effective option in many industrial or construction environments.

In contrast, other options do not offer the same level of protection. For example, a face shield can provide additional face protection but is not sufficient on its own for safeguarding the eyes, as it does not create a complete seal around the eyes. Contact lenses also do not offer any physical protection against hazards and can even worsen eye injuries if debris becomes trapped under them. Regular glasses may provide some level of protection against minor risks but typically do not meet the safety standards required for work environments with potential hazards. Thus, the choice of safety goggles is the most appropriate for ensuring adequate eye protection in a workplace setting.
