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

Safety glasses are specifically designed to protect the eyes from various hazards present in a shop environment, such as flying debris, chemicals, or intense light. They are constructed from impact-resistant materials that can withstand high levels of stress, ensuring that the wearer's eyes remain protected in potentially dangerous situations. Additionally, safety glasses often feature side shields to provide additional coverage and minimize exposure to particles that could enter from the sides.

In contrast, reading glasses are meant for magnification and would not provide adequate protection against physical hazards. Sunglasses are designed to protect against UV rays and glare but do not offer the durability or coverage required in a shop setting. Prescription glasses, while helpful for vision correction, typically lack the robust features that safety glasses possess and are not designed specifically to protect against workplace hazards. Thus, safety glasses are the most appropriate choice for ensuring eye safety in a shop environment.
