• A. 2.0mm
• B. 3.0mm
• C. 4.0mm
• D. 5.0mm

Answer: (B)

The correct minimum center thickness required for lenses made for safety eyewear is 3.0mm, as specified by federal regulations to ensure adequate protection against impact and injury. Safety eyewear must meet stringent standards to provide the necessary safety and durability in hazardous environments. A center thickness of 3.0mm is established to balance between providing sufficient strength to withstand impacts while also considering comfort and visual clarity for the wearer. This thickness helps to minimize the risk of lens breakage, thereby enhancing the overall safety provided by the eyewear.
