ESS Cross Series/ Canadian Forces Discount Program


Since 2008 I have worn one pair of sunglasses and one pair only, the ESS Crossbow Ballistic Eye Shield. Over the years I have pretty much owned every lens, and frame with the exception of the polarized lenses. They are modular form fitting to my face and provide complete peripheral protection. They have become somewhat of a signature for me. I came across them at Atlantic Police Supply Distributors in Bedford, NS closed since 2009 or so. The price point was just right ringing in at about $120.00 for two frames and three lenses; black, white, and yellow.

ESS Eye Wear and Ballistic Googles exceed most if not all military testing standards and have become standard issue for all U.S. Department of Defence Employees. ESS Googles are standard issue for all flight deck and aviation crews within the U.S. Navy.

The Eye Shield surpasses the test as defined by the American National Standards Institute (ANSI) Z87.1, high-velocity impact protection requires a ¼ inch steel shot fired at 102 Mph (163km/h) at a lens straight on from three different heights at 7 different angles


HIGH IMPACT

Within ANSI Z87.1 the lens ust hit with a 500g (1lb) metal spiked dropped from a height of 51 inches, no frame parts or lens fragments maybe ejected during the impact.

ESS Eye Pro exeeds the U.S. Military Standard which is approximately six times that of the ANSI standard. The U.S. Military standard requires that ballistic eyewear must be able to withstand up to a .15 calibre at 640-60ft/s for spectacles and .22 calibre at 550/560 ft/s for goggles.




PRISMATIC POWER

Prismatic Power is the measurement of how much light bends through a lens. The effect of excessive prism is that objects viewed through a lens aren’t actually where they appear to be. The test also measures the prism imbalance in the left and right sides of the lens, which causes the eyes to fatigue as they work to overcome the artificial “double vision” induced by an unbalanced lens.






A laser fixture is set up 30 feet from the NBS target and is fired through each lens at the target. The better the optics, the less bending of the laser beam is observed; a lens without induced prism will allow the laser’s path to continue directly at the center of the NBS target. Bear in mind when viewing the amount of prism that the effects of the distortion are more significant at distances greater than 30 feet.



REFRACTIVE POWER: ANSI Z87.1 OPTICS TEST #7.4.3.3

Lens refraction is a measure of what many people refer to as distortion or blurriness. The ANSI Z87.1 Refractive Power test requirements allow for a moderate amount of refraction in a safety lens. The lines in the NBS Definition Pattern are used to measure this lens characteristic.

Cross Series ™ Ballistic Eyewear


Over the years ESS has developed three distinct eye shields each with their own purpose and price point, the Crossbow being their first development. Later would come the suppressor series with a similar frame but with thinner arms to allow for a more comfortable fit when wearing ear pro or communications gear. The crosshair is developed as an entry level eye shield with a price point of $40.00 for a single lens and frame and $72.50 for the standard two frame, two lens package. In comparison to other ballistic eye shields the ESS is both stylish and highly affordable for the level of protection it offers.
