Which safety equipment is essential when performing tasks that pose a risk to the eyes?

Protective eyewear is essential when performing tasks that pose a risk to the eyes because it serves as a barrier against potential hazards such as flying debris, chemicals, or intense light. This type of equipment is specifically designed to shield the eyes from injuries that can occur in various work environments, especially in construction and lineman tasks. The use of protective eyewear helps in preventing both short-term and long-term damage to the eyes, ensuring that the worker maintains their vision and overall safety while on the job.

In contrast, the other options, such as earplugs, hard hats, and gloves, serve important safety functions but are geared towards protecting different parts of the body. Earplugs protect hearing, hard hats protect the head from impact, and gloves protect the hands from cuts and abrasions. While each piece of equipment has its specific purpose, protective eyewear is the only option that directly addresses risks to the eyes, making it the appropriate choice for this question.
