Revision continues to invest resources in advanced coating technologies in order to offer soldiers fog-free protective eyewear solutions.
Eyewear fogging, one of the leading complaints from soldiers, can now be combated for both goggles and spectacles. Through continuous research and experimentation, Revision has now taken anti-fog technology to the next level with their new OcuMax® Plus anti-fog lens coating.
“For a Soldier, a fogged lens may force him to remove his spectacles or goggles; leaving the Soldier’s sight unprotected and disrupting his concentration from the mission at hand,” says Eric Hounchell, Vice President, Optics at Revision. “We are confident that this new coating is the best-in-class anti-fog solution, and in applying it to our eyewear, is in keeping with Revision’s rigorous standards for top performing military eye protection.”
To help understand why fogging occurs on eyewear, the science behind fogging needs to be understood. Fogging happens due to an abrupt change of temperature; when the temperature of one surface of a transparent lens drops below a dew point due to a difference in temperature or humidity. Condensation appears on the surface of the lens and forms fine but randomly spaced droplets, resulting in scattering the light that travels to the wearer’s eyes. This causes impaired vision. The performance of an anti-fog coating is related to its ability to prevent water condensation on the surface in form of droplets. Revision’s R&D team has found a unique chemical combination that results in a robust, durable anti-fog solution that can withstand in-the-field use.
Using its in-house anti-fog chamber, Revision tested the OcuMax Plus coating to the EN 166 standard, one of the only quantifiable standards applied to military eye protection. The result: fog resistance was excellent, with an OcuMax Plus coated lens remaining fog-free for over 100 seconds – 10 times better than competitors’ eyewear coatings tested to the same EN standard.
While the coating has been proven in the lab, it can also withstand the rigors of combat. In the field, users constantly handle, touch, and clean their lenses. OcuMax Plus has been designed specifically to perform in tough battlefield environments.
Revision has recently rolled out its new OcuMax Plus coating on the majority of its eyewear products including its StingerHawk spectacles as well as Desert Locust, Bullet Ant and Wolfspider goggles. This coating also prevents scratches, streaks and smears in order to prevent optical distortions.
