What is the primary function of glasses or spectacles in a workplace safety context?

The primary function of glasses or spectacles in a workplace safety context is to shield from hazards. While improving vision is an important aspect of eyewear, in a safety setting, the primary concern is protection. Safety glasses are designed not only to provide clarity of sight but also to protect the eyes from potential hazards such as flying particles, chemicals, and harmful light. This protective feature is crucial in many work environments, including construction sites, laboratories, and manufacturing facilities, where eye injuries can occur from various sources.

Options that focus on enhancing appearance or correcting color blindness are secondary to the primary safety function of eyewear. While prescription glasses may be necessary for vision correction, safety glasses often incorporate additional features that enhance protection and compliance with safety standards, making them essential in safeguarding workers' eyes from injury.
