Q: Can all tinted glasses protect against ultraviolet (UV) rays from sunlight?
A: Not necessarily. First, if the lens material is polycarbonate, certain brands use polycarbonate with added UV inhibitors, which means that regardless of the lens color, it provides UV protection. However, if some safety glasses use regular polycarbonate lenses, they do not have UV protection. Secondly, lens color is not related to UV protection.
Q: Can sunglasses with UV protection be used for welding protection?
A: No. While UV protection glasses can block 99% or more of ultraviolet (UV) rays from sunlight, they are only effective against UV radiation. Welding arcs emit not only UV radiation but also infrared (IR) radiation and extremely intense visible light. Ordinary UV protection glasses do not provide adequate protection against these hazardous rays, making them unsuitable for welding. Welders must use specialized welding safety goggles or helmets for effective protection.
Q: How should employees with nearsightedness wear protective eyewear?
A: They can choose specialized over-the-glasses (OTG) safety glasses or goggles that are designed to be worn over prescription eyeglasses.
Q: Can a face shield be worn alone?
A: No. A face shield serves as secondary protection, designed to protect the face from hazards. However, due to the gaps between the shield and the face, there is a risk of eye injury. Therefore, we recommend that users wear appropriate safety glasses along with the face shield to ensure dual-layer eye protection.
Q: Will wearing protective eyewear together with respiratory protection interfere with each other and reduce protective performance?
A: In general, when dust masks are worn together with safety glasses or goggles, the exhaled air leaking from the nose clip may cause fogging on the lenses. To prevent this, anti-fog safety glasses or goggles with excellent anti-fog performance should be selected when used together with respiratory protection.
