Final answer:
Contact lenses do not provide additional protection at a worksite over safety glasses and should be used with appropriate protective eyewear.
Step-by-step explanation:
The statement that contact lenses provide additional protection for a worker over and above safety glasses is false. While contact lenses have several advantages over glasses, such as superior peripheral vision and correction of corneal astigmatism, protective eyewear is still essential for safety at a worksite. Safety glasses or goggles are designed to provide full coverage to protect the eyes from various hazards, including impact, dust, chemicals, and ultraviolet radiation. Contact lenses alone do not offer protection from these hazards and should be worn in conjunction with appropriate safety eyewear.
