ANSI Z87.1+ 

ANSI Z87.1+ is at the center of the Gargoyles protection philosophy, and all styles in this category meet or exceed ANSI Z87.1+ standards for high mass and high velocity impact, coverage and optical clarity. Excellent for military, law enforcement, and first-responder professionals.

ANSI Z87.1+ HIGH VELOCITY TEST
A quarter-inch steel projectile is shot at the lenses at 165 km/hr. The sunglasses must be able to take this punishment without the lenses cracking, breaking, falling out of the frame, or touching the eye.

ANSI Z87.1+ PRISM TEST
Two lasers are aligned to match up to a single point from a 35 foot distance. Sunglasses are then placed in front of the two beams. In order to pass this test, the beams must maintain their original pinpoint trajectory and meet at the same point as before, showing that the glasses do not distort light positively or negatively. While other sunglasses distort the direction of the laser beam, Gargoyles maintains the original pinpoint optics.

ANSI Z87.1+ VISUAL CLARITY TEST
A resolution chart is placed at a distance of 20 feet, with lines at both the X and Y axis. When the sunglasses are placed in front of an eyepiece, the viewer must be able to see at least 20 lines of resolution from 20 feet away clearly and distinctly without any blurring or distortion.

OLEOPHOBIC AND ANTI-REFLECTIVE TREATMENTS
All Gargoyles sunglasses feature oleophobic and anti-reflective treatments to repel water, oil, and smudges, and to reduce glare. These treatements work together to facilitate cleaning, increase the lens' resistance to scratching, and improve the overall visual experience.
