The 3M SecureFit 400 SF410AS features a mirror-coated polycarbonate lens designed for tasks requiring frequent transitions between indoor and outdoor environments. The indoor/outdoor (I/O) mirror tint reduces glare outside while remaining usable under artificial lighting indoors. Anti-scratch coating extends lens life on job sites. Pressure Diffusion Temple Technology provides a self-adjusting fit, and lenses block 99.9% of UV rays. Meets ANSI Z87.1-2010 and CSA Z94.3 high-impact requirements. Sold individually; also available in 20-unit case packs.
Can I wear these indoors under factory lighting?
Yes. Indoor/Outdoor mirror lenses are designed for both environments. Several users report wearing them in factory settings where the mirror tint tones down harsh overhead lighting without making it too dark to see clearly.
Do these have an anti-fog coating?
The SF410AS has an anti-scratch coating but does not include an anti-fog coating. If you need anti-fog in humid environments, consider the SF401AF or the SecureFit 400 with foam gasket variant.
Are these suitable as outdoor sunglasses for construction work?
They provide UV protection and glare reduction via the mirror coating, making them a practical choice for outdoor construction or landscaping. However, they are not rated as sunglasses and do not meet sunglass optical standards.
What is the ANSI rating?
The SF410AS meets ANSI Z87.1-2010 high-impact requirements and blocks 99.9% of UV rays.
Are the lenses interchangeable between models in the 400 series?
No. The lens and frame of SecureFit 400 glasses are manufactured as an integrated unit. Lenses are not user-replaceable.
