Which of the following is not considered effective eye protection?

Regular prescription glasses are not considered effective eye protection in environments where hazardous materials or conditions may pose a risk to eye safety. While they provide vision correction, they often do not meet the safety standards required to protect against chemical splashes, flying debris, or high-impact activities.

In contrast, safety goggles are designed to provide a secure fit around the eyes and often include features that protect against impacts and chemical splashes. Face shields provide broader protection for the face, although they are typically used in combination with safety goggles for full eye protection. Safety glasses are specifically designed to protect the eyes from impacts and can also offer some level of protection against dust or flying particles. Therefore, when it comes to ensuring eye safety, regular prescription glasses fall short because they lack the necessary protective qualities required in many work and hazardous environments.
