Ballistic eyewear is a form of glasses or goggles that protect from small projectiles and fragments. For the U.S. military, choices are listed on the Authorized Protective Eyewear List (APEL). Ballistic eyewear including examples that meet APEL requirements are commercially available for anyone who wishes to buy it. The history of protective eyewear goes back to 1880 and extends through to World War I and the present. There are three standards that are currently used to test the effectiveness of ballistic eyewear. These include a U.S. civilian standard (ANSI Z87.1 – 2010), a U.S. military standard (MIL-PRF-31013), and a European standard (EN 166, 169, 170 and 172). Types Safety glasses, sunglasses and goggles that claim to meet ballistic safety standards are widely available. Some can accommodate prescription lenses. Although not required, it is recommended that all eyewear meet ANSI Z87.1, but for ballistic protective eyewear it is required that it meets military standards for impact protection (MIL-DTL-43511D clause 3.5.10 for goggles and visors and MIL-PRF31013 clause 3.5.1.1 for spectacles). Though these standards have been very commonly used especially by NATO forces, an update on MCEPS of January 2013 now reference these clauses in MIL-PRF-32432. Ballistic sunglasses or prescription eyeglasses must meet the same requirements. In brief, the U.S. military standard requires that ballistic eyewear must be able to withstand up to a 3.8 mm (.15 caliber) projectile at ) for spectacles and 5.6 mm (.22 caliber) projectile at for goggles. The European standard identifies four levels of impact protection. Manufacturers offer a variety of styles and colors to meet different needs and preferences. Some make claims of superior side protection, comfort, anti-fog coatings, interchangeable lenses, transition lenses, etc. At least one product from more than a half dozen manufacturers are listed on the U.S. Army’s Authorized Protective Eyewear List (APEL). Some options, including the Wiley X PT-1 and Talon as well as Revision's Sawfly and the Desert Locust Goggle can be obtained in prescription lenses that meet the ballistic protection standards. In addition to impact requirements, the U.S. Army requires for its soldiers that ballistic eyewear be functional, reasonably comfortable, not faddish (i.e., no bright colors or distracting designs) and able to be disinfected.
