4x4 polarized protective eyewear

The 4x4 polarized protective eyewear is for workers who need protection from impact hazards and who face daily glare from light bouncing off flat, reflective surfaces. The 4x4 has been independently tested and certified to exceed the ANSI Z87.1+ and CSA Z94.3 standards. Unlike standard shaded lenses, these lenses contain a special optical filter that absorbs the horizontal component of light, seen as glare, and transmits only the vertical component. In addition to being annoying, glare is dangerous because some light waves can be intense enough to cause permanent eye damage. All 4x4 products have a durable, lightweight frame with dual wraparound polycarbonate lenses designed to look like fashionable sunglasses. A soft nosepiece provides a snug fit and flexible temple tips relieve pressure behind the ears. An anti-scratch coating protects the lenses from minor damage to preserve a clear view of the jobsite.
