The 3M SecureFit 400 Series SF405SGAF-BLA safety glasses combine a bold black and brown frame with a brown-tinted Scotchgard Anti-Fog lens for enhanced clarity in variable-light conditions. Pressure Diffusion Temple Technology allows the curved temples to self-adjust to the wearer's head, distributing pressure to the back of the head for lasting comfort. U6-rated polycarbonate lenses absorb 99.9% of UVA, UVB, and UVC rays. The Scotchgard coating provides more durable anti-fog performance than standard coatings. Meets ANSI Z87.1-2020 and CSA Z94.3-2007 high-impact requirements.
What is Scotchgard Anti-Fog coating?
3M Scotchgard Anti-Fog Coating is a more durable anti-fog treatment than standard single-layer coatings. It is engineered to help workers see clearly for longer periods in hot, humid, or high-temperature work environments.
What does the brown lens tint do?
Brown or amber-tinted lenses enhance contrast and reduce blue light, which improves depth perception and visibility in variable or overcast outdoor lighting. They are not recommended for very dark indoor spaces.
Are these rated for high impact?
Yes. The SF405SGAF-BLA meets the High Impact Requirements of ANSI Z87.1-2020 and CSA Z94.3-2007.
How does the Pressure Diffusion Temple Technology work?
Slotted ribs along the temples allow the arms to flex and equalize pressure. The curved temples contact the back of the skull rather than squeezing the temples, which reduces headaches during extended wear.
Can the nose piece be replaced if it comes off?
The one-piece soft nose bridge is integral to the frame on some SecureFit 400 models. Check the product listing or contact 3M for replacement part availability.
