Uncompromising Protection
Wiley X is built on protection and safety. It is the core DNA of the brand. All WX eyewear and goggles are tested to meet or exceed ANSI optical safety standards and are all certified to EN.166. Additionally, some models are also tested to meet or surpass the ballistic standardization – the MIL-PRF – as defined by the US military. As the only eyewear brand who certifies their entire line to EN.166, we truly differentiate the Wiley X brand and underlines our commitment to our users’ safety.
En.166
EN.166 is the European optical standard when it comes to the requirements for protective eyewear, including goggles. It specifies the minimum requirements that protective eyewear must meet in terms of a range of performance tests. At Wiley X we pride ourselves in certifying all our eyewear and goggles to the EN.166 optical safety standard. However, not all eyewear/goggles are certified to the same EN.166 version. At Wiley X we certify to either EN.166F, EN.166S, or EN.166B. Each standard version involves a different test which the eyewear has been subjected to and passed.
EN.166F
Eyewear that is certified to EN.166F has been subjected to a low energy impact test, which also give you protection against blunt force. This test dictates that a pair of eyewear (including both frame and lens) must by hit with a 6mm steel ball that weighs 0.86g, which is dropped down onto to eyewear from 1.3 meters at 162 km/h. The eyewear can be EN.166F certified if the lenses remain intact and in unshattered frame.
EN.166S
Eyewear that is certified to EN.166S has been subjected to a particular stress test. The eyewear can be EN.166S certified if the lenses do not shatter and remain in the frame, which must also stay intact. According to this specific stress test, a pair of eyewear (including both frame and lens) must withstand a 22 mm steel ball, weighing 43 grams that is dropped down on it from 1.3 meters at 18km/h. The test will also ensure that you will be protected against large amount of blunt force.
EN.166B
EN.166B is the specific European optical safety standard for goggles and involves a medium energy impact test. This test demands that the goggle must withstand a 6mm ball that weighs 86 grams and is shot at the goggles at a speed of 432 km/h. With a goggle that is EN.166B certified, you are ensure a pair of goggles that is tested to meet the toughest standard.
MIL-PRF
Several of the Wiley X tactical eyewear is tested to meet or exceed the ballistic standardization, as defined by the US military. In this context MIL-PRF refers to a performance specification in relation to military safety. This means that MIL-PRF involves the standards and demands that our eyewear must meet in terms of performance, specifically the ballistic fragmentation impact requirements.
MIL-PRF-32432(GL)
The eyewear and goggle are tested to meet or exceed this test, meaning that the eyewear or google must provide the user with protection against ballistic fragmentation while remaining intact both upon and after impact. For the MIL-PRF-32432(GL) this means that the eyewear must remain intact during and after a .15 caliber projectile is fired at it at 702-724 km/h, whereas a goggle must remain intact during and after a .22 caliber projectile is fired at it at 604-614 km/h.
MIL-PRF-32432A
For some of our eyewear we test it to meet or exceed the MIL-PRF-32432A. Like the MIL-PRF-32432(GL) this is also a test to ensure the user’s protection against ballistic fragmentation, and the eyewear and goggles must also withstand this impact without shattering or separating. According to MIL-PRF-32432A, eyewear must withstand a .15 caliber projectile fired at it at 786-796 km/h, whereas for goggles it is a .22 caliber projectile fired at it at 636-647 km/h.
ANSI
All Wiley X eyewear is tested to meet or surpass the optical safety standards as defined by the American National Standards Institute (ANSI), who have defined the testing standards for safety eyewear in the US. As an American brand, we test our eyewear and goggles to pass the high velocity impact test and the high mass impact test, as defined by ANSI.
High Velocity Impact
All Wiley X frames and lenses are tested to withstand the impact of a 6.35 mm steel ball fired at 164.6 km/h. Neither the lenses or frames must shatter, and if it is a pair of full eyewear, the lenses must remain intact with the unshattered frame.
High Mass Impact
All Wiley X frames and lenses are tested to withstand the impact of a 500 grams pointed projectile that is dropped down on the lens/frame/full eyewear from a height of 127 cm. Neither the lenses or frames must shatter, and if it is a pair of full eyewear, the lenses must remain intact with the unshattered frame.
