ANSI Z87.1<\/h2><\/div><\/div>[vc_column_text css=\u201c\u201d]\n

ANSI Z87.1<\/strong> is an important norm for the eye pro\u00adtec\u00adtion indus\u00adtry in the USA. This stan\u00addard covers dif\u00adfe\u00adrent types of eyewear: spec\u00adta\u00adcles, goggles and face shields as well as pre\u00adscrip\u00adti\u00adon and plano lenses. ANSI Z87.1 gives general descrip\u00adti\u00adons and requi\u00adre\u00adments to the eyewear and pro\u00advi\u00addes the test methods.
\nThe general requi\u00adre\u00adments to the eyewear include the optical quality, lumi\u00adnous trans\u00admit\u00adtance, refrac\u00adti\u00adve powers and haze for clear lenses. The general phy\u00adsi\u00adcal requi\u00adre\u00adments are no sharp edges and no other defects that may cause dis\u00adcom\u00adfort or injury. The minimum covera\u00adge area is also checked to make sure that eyewear doesn\u2019t rest\u00adrict the view field of the user. The \u201ddrop ball test\u201d is appli\u00adca\u00adble only in case of no high mass impact and velo\u00adci\u00adty tests are done. The eyewear has to endure also the igni\u00adti\u00adon and cor\u00adro\u00adsi\u00adon (if there are any metal parts) tests. Eyewear shall provide a good and tight lateral covera\u00adge of the eye. The high mass and high velo\u00adci\u00adty tests are passed if no part of the eyewear becomes detached from the inner surface, if there is no frac\u00adtu\u00adre, no com\u00adple\u00adte pene\u00adtra\u00adti\u00adon of the pro\u00adjec\u00adti\u00adle through lens or frame, no rupture of the lens.
\nANSI Z87.1 lays down also the requi\u00adre\u00adments to the optical radia\u00adti\u00adon pro\u00adtec\u00adtion. Among the common indus\u00adtri\u00adal filters like infrared and visible light pro\u00adtec\u00adtion (for welding), the stan\u00addard lays down the cri\u00adte\u00adria for pro\u00adtec\u00adtion against ultra\u00advio\u00adlet radia\u00adti\u00adon. While the first two are not needed in the bal\u00adli\u00adstic glasses, the latter is very important. All Swis\u00adseye tac\u00adti\u00adcal lenses hence offer a com\u00adple\u00adte UV pro\u00adtec\u00adtion up to 400 nm.<\/p>\n
