Optimised for medium to low light performance, the Saber Advanced with Vermillion Shield enhances contrast and target visibility during changing weather or indoor/outdoor transitions. The 45% light transmission vermillion lens filters high-energy visible blue light to improve definition and reduce visual fatigue over extended use. Built on Wiley X’s proven semi-rimless platform, the frame uses Triloid nylon for its lightweight yet durable structure, while adjustable telescoping temples and a 360° wire-core nosepiece ensure comfort and secure fit across a wide range of face shapes. The lens is made from shatterproof Selenite polycarbonate, meeting ANSI Z87.1, EN 166F, and MIL-PRF-32432(GL) ballistic standards. A T Shell coating improves resistance to everyday abrasions, keeping vision clear in fast-paced environments. Professionals who operate in lighting conditions that shift from cloudy to artificial or shadowed settings often struggle with eye strain and reduced contrast—this vermillion setup directly addresses those challenges with enhanced target clarity and visual balance. The included elastic strap and NVG compatibility further ensure tactical readiness
