SecureFit 400 indoor/outdoor polycarbonate AS safety glasses are lightweight, rimless safety glasses designed for professional eye protection in environments with changing light conditions. The glasses are suitable for both indoor and outdoor work, where transitions between different light levels can otherwise be disruptive. The mirrored polycarbonate lens helps reduce glare and makes light changes less noticeable, while filtering 99.9% of UVA and UVB radiation.

The glasses are manufactured using 3M™ SecureFit™ Pressure Diffusion Temple Technology, which automatically adapts to the wearer’s head shape. Pressure is evenly distributed across the temples, providing a secure and comfortable fit for most head sizes, even during extended wear. This self-adjusting design is also known from the SecureFit 200 Series and is carried forward here with the same focus on comfort and stability.

Wide, flexible temple arms provide side protection and integrate well with earmuffs. Soft, adjustable nose pads help reduce slippage during movement and allow individual fit adjustment. The lens features an anti-scratch coating that supports durability and consistent visibility during daily use.

The safety glasses have no seal and are therefore not intended for protection against liquids, dense dust or chemical exposure. The product complies with EN166:2001 and is CE approved.
