Wiley X Saber Advanced Lens

These are replacement lenses, not a pair of glasses. They replace original lenses that are lost, misplaced, or damaged.

Four standards, including one NATO standard

This is the most documented lens in the range. In addition to the US military specification MIL-PRF-32432A, it also meets STANAG 2920/4296.

STANAG is a NATO standardization agreement: 2920 defines the ballistic test method for protective materials, and 4296 is the standard for eye protection. This is a rare reference for a replacement lens.

VLT 89%: Protection without tint

Almost nine-tenths of the light passes through the lens. The manufacturer claims natural color rendition, with no impact on contrast.

This is the lens for low light and night — and the one you leave installed when you don't know what's next.
