Answer:
The 3M 1611 weighs approximately 39 grams and delivers low-energy impact protection rated at 45 m/s (Class F under EN 166). It features Optical Class 1 polycarbonate lenses providing 99% UV absorption and an anti-scratch surface coating.
The 3M™ 1611 Visitor Spectacle is engineered for industrial eye protection against airborne particulates, environmental dust, and metal filings. Constructed entirely from durable polycarbonate across both the single-ocular lens and fixed-length temple arms, the complete unit has an approximate weight of 39 grams.
Key performance ratings and optical metrics include:
- Impact Resistance: Rated Class F under EN 166:2001, providing certified resistance against high-speed particles at low energy (up to 45 m/s).
- Optical Quality: Rated Optical Class 1, ensuring minimal spherical and astigmatic refractive distortion for continuous, prolonged wear without eye strain.
- UV Radiation Protection: Polycarbonate construction provides 99% UV absorption (marked 2C-1.2 under EN 170).
- Surface Treatment: Integrated anti-scratch coating to maintain lens clarity in abrasive industrial plant environments.
