This explains the high quality demands that are placed on our safety eyewear.<\/p>\n<\/div><div class=\"fusion-title title fusion-title-5 fusion-sep-none fusion-title-text fusion-title-size-three\" style=\"--awb-margin-top-small:10px;--awb-margin-right-small:0px;--awb-margin-bottom-small:10px;--awb-margin-left-small:0px;\"><h3 class=\"fusion-title-heading title-heading-left\" style=\"margin:0;\">Personal eyewear is not safety eyewear<\/h3><\/div><div class=\"fusion-text fusion-text-3\"><p>Personal eyewear is not suitable for safety eyewear, because they do not provide sufficient protection against the hazards in the workplace. However, employees often use old personal eyewear, the eyewear lenses of which in most cases have redundant optical strengths. Even in the case of normal and routine work processes, there is always the danger that the eyes can be affected by things like metal shavings, wood splinters or liquids. Such injuries can lead to permanent visual impairment or even blindness. Discerning employers make suitable eye protection available to all at risk. Customised corrective safety eyewear are to be explicitly recommended Personal corrective eyewear does not afford the required safety effect. Goggles, over-goggles or visors can be worn over personal eyewear in the case of short-term use that lasts only a few minutes. The insurance association however explicitly recommends the use of prescription safety eyewear, because this is the only way to combine both the safety function and corrective effect (BGR 192 Section 3.2.2.2, Prescription Safety Eyewear).<\/p>\n<\/div><\/div><div class=\"nav fusion-mobile-tab-nav\"><ul class=\"nav-tabs\" role=\"tablist\"><li role=\"presentation\"><a class=\"tab-link\" data-toggle=\"tab\" role=\"tab\" aria-controls=\"tab-e52c0088f3d1a6e221e\" aria-selected=\"false\" tabindex=\"-1\" id=\"mobile-fusion-tab-testingproceduresforeyewearframesandeyewearlenses\" href=\"#tab-e52c0088f3d1a6e221e\"><h4 class=\"fusion-tab-heading\">Testing procedures for eyewear frames and eyewear lenses<\/h4><\/a><\/li><\/ul><\/div><div class=\"tab-pane fade fusion-clearfix\" role=\"tabpanel\" tabindex=\"0\" aria-labelledby=\"fusion-tab-testingproceduresforeyewearframesandeyewearlenses\" id=\"tab-e52c0088f3d1a6e221e\">\n<h4>Ball drop test \u2013 Increased stability (EN166S)<\/h4>\n<p>The object to be tested must withstand the impact of a steel ball with a nominal diameter of 22mm and a weight of at least 43g from a distance of 1.30m. The speed of the steel ball in this case is around 5.1 m\/s (11.5mph). After the test, the material is examined for breakage or deformation.<\/p>\n<h4>Firing Test &#8211; Low Energy Impact (F) and Medium Energy Impact (B)<\/h4>\n<p>The tested frame or lens must withstand the impact of a steel ball with a nominal diameter of 6mm and a weight of at least 0.86g.

The heated surface is pressed up against the eyewear frame or the eyewear lens. The material must not ignite at any time during the contact period of 5 seconds.<\/p>\n<h4>Resilience in the case of increased temperature\/ageing<\/h4>\n<p>The eyewear being tested is placed in a heating cabinet and heated to a constant temperature of 55\u00b0C, for a period of 60 minutes. It is then also inspected for deformation, ageing or changes in the optical quality.<\/p>\n<\/div><div class=\"nav fusion-mobile-tab-nav\"><ul class=\"nav-tabs\" role=\"tablist\"><li role=\"presentation\"><a class=\"tab-link\" data-toggle=\"tab\" role=\"tab\" aria-controls=\"tab-e73f762bf952ee7e24a\" aria-selected=\"false\" tabindex=\"-1\" id=\"mobile-fusion-tab-additionaltestingproceduresforeyewearframes\" href=\"#tab-e73f762bf952ee7e24a\"><h4 class=\"fusion-tab-heading\">Additional testing procedures for eyewear frames<\/h4><\/a><\/li><\/ul><\/div><div class=\"tab-pane fade fusion-clearfix\" role=\"tabpanel\" tabindex=\"0\" aria-labelledby=\"fusion-tab-additionaltestingproceduresforeyewearframes\" id=\"tab-e73f762bf952ee7e24a\">\n<h4>Corrosion resistance<\/h4>\n<p>The eyewear frame being tested is placed in a boiling sodium chloride solution for a period of 15 minutes. Thereafter, in a sodium chloride solution at room temperature for a further 15 minutes. This is then rinsed and dried for visual inspection. The surfaces of all metal parts must be found to be smooth and corrosion free.<\/p>\n<h4>Field of vision<\/h4>\n<p>The eyewear frame must demonstrate an adequate fiel of vision. In addition, field lines of vision are simulated on a standardised headform by means of a laser. The frame is only approved if the predefined minimum field of vision is maintained.<\/p>\n<h4>Side protection \/ Coverage area<\/h4>\n<p>In the same manner as with the field of vision measurement for frames, the side protection on the eyewear frame must not restrict the field of vision of the person wearing the glasses.

The lens is then tested by means of an optical scattered light test (see scattered light).<\/p>\n<h4>Ageing resistance against UV radiation<\/h4>\n<p>The lens under test is exposed to the radiation from a strong UV lamp for a period of 50 hours. This simulates the storage and\/or use of safety eyewear with glass lenses in sunlight for a period of approx. 2 years. Following the test, a measurements are taken to ensure light transmission and scattered light limitations conform to the specified standard.<\/p>\n<h4>UV protection filter<\/h4>\n<p>In cases of long and unprotected exposure to UV, there exists a danger of serious eye damage, such as retinal lesions and cataracts. Therefore, the lenses are tested and examined to ensure the required UV protection of the lenses is guaranteed.<\/p>\n<h4>Scattered light<\/h4>\n<p>Scattered light is an optical effect, which blurs an ob-served image and reduces the contrast. During testing, a clearly defined laser beam is guided through the lens at a certain angle. By means of a radiation receiver, a com-parison is done to check whether there is a possible de-viation or a scattering of the light stream.<\/p>\n<h4>Light transmission level<\/h4>\n<p>The level of light transmission offered by a lens is mea-sured by means of a spectrophotometer. Eyewear lenses that are intended exclusively for the purpose of protecting the eyes against mechanical or chemical hazards, must have a light transmission above 74.4%.<\/p>\n<h4>Signal light detection<\/h4>\n<p>A restricted ability to observe the signal colours, red, yellow, green and blue results in significantpotential for hazard. By measuring the corresponding light wave-lengths, the lens can be tested as to what extent true signal colours are observed.<\/p>\n<h4>Refraction index \/ spherical and astigmatic effect<\/h4>\n<p>The lens is inspected with a lens meter based on define correction values and the result must be within specifie tolerances. Only then does the lens obtain the best pos-sible category for optical quality \u2013 Category 1.<\/p>\n<h4>Material and surface quality<\/h4>\n<p>The lens is examined for defects, which may influenc the optical quality. Such defects may include scratches, inclusions, blisters or opacities.<\/p>\n<\/div><div class=\"nav fusion-mobile-tab-nav\"><ul class=\"nav-tabs\" role=\"tablist\"><li role=\"presentation\"><a class=\"tab-link\" data-toggle=\"tab\" role=\"tab\" aria-controls=\"tab-9402ab3715493179840\" aria-selected=\"false\" tabindex=\"-1\" id=\"mobile-fusion-tab-certificationandlabelling\" href=\"#tab-9402ab3715493179840\"><h4 class=\"fusion-tab-heading\">Certification and Labelling<\/h4><\/a><\/li><\/ul><\/div><div class=\"tab-pane fade fusion-clearfix\" role=\"tabpanel\" tabindex=\"0\" aria-labelledby=\"fusion-tab-certificationandlabelling\" id=\"tab-9402ab3715493179840\">\n<h4>The Certificate<\/h4>\n<p>Only after successfully completing all testing procedures, does the safety eyewear obtain approval for use as safety eyewear. For the corresponding test result, each safety eyewear model is issued with a type approval certificate.
