Over deze norm
1.1 This specification covers eye protectors, exclusive of helmet-mounted visors, designed for use by riders of motorcycles, mopeds, and snowmobiles for off road use that minimize or significantly reduce injury to the eye and adnexa as a result of impact and penetration by objects that may be kicked up from the road, track, trail, or snow surfaces and made airborne and, as such, likely to cause eye discomfort or injury. This specification does not address shield-type eye protectors such as are connected to, integral to, and/or supported by protective helmets. Protective eyewear offers protection only to the eyes and does not protect other parts of the head, face, or neck.
1.3 This specification does not apply to prescription eyewear. (Warning—Impact-resistant prescription spectacles that conform to the standard specifications of ANSI Z87.1 should be used if spectacles are to be worn under goggle-type eyewear as covered by this specification.)
