What type of glasses should always be worn in a shop environment for safety?

In a shop environment, safety glasses are essential because they provide protection against a variety of hazards commonly found in such settings. These hazards might include flying debris, splashing chemicals, and intense light from welding or machining processes. Safety glasses are specifically designed with impact-resistant lenses and side shields to offer better coverage from projectiles and harmful substances.

While reading glasses, sunglasses, and prescription glasses have their own functions, they do not offer the same level of protective features required in a potentially hazardous environment. Reading glasses are intended for close vision tasks, sunglasses primarily protect against UV rays but do not shield against impact, and prescription glasses don't typically have the necessary impact resistance or side coverage. Thus, wearing safety glasses is crucial to ensure that you have the appropriate protection and comply with safety regulations in a shop environment.
