Which item is NOT effective for preventing eye injuries?

Prescription glasses are typically not designed or manufactured to provide adequate eye protection in environments where there is a risk of eye injury. While they may correct vision, they lack the necessary features that safety equipment provides, such as impact resistance, side shields, or lenses designed to withstand chemical splashes and flying debris.

In contrast, safety glasses, face shields, and goggles are specifically designed for protective purposes. Safety glasses often come with impact-resistant lenses and may also have side shields to protect from flying particles. Face shields provide a full range of protection for the entire face, making them suitable for tasks where splashes, sprays, or flying debris might occur. Goggles form a complete seal around the eyes, ensuring no irritants can enter from the sides, making them ideal for environments with hazardous vapors or liquids.

This distinction underscores the importance of selecting the correct type of protective eyewear based on the associated risks of each task or environment.
