Designer frames, celebrity trends, and silly fads often influence our purchases, and we forget the importance of sun protection, which can cause long-term damage to your eyes from glare and harmful ultraviolet light, which can cause cataracts and may be linked to macular degeneration. Children are vulnerable to UV because they have larger pupils and clearer lenses in their eyes. Sunglasses are categorized as Class 1 of personal protection equipment under European Regulation 2016/425. Our HOKLAS-accredited laboratory facilities provide you with one-stop simple solutions for PPE product compliance with testing and certification requirements against all applicable international and national standards, such as: International: ISO 12312.1, ISO 12312.3Europe: EN ISO 12312.1, EN ISO 12312.3USA: ANSI Z80.3China: GB 39522.1Taiwan: CNS 15097Australia / New Zealand: AS/NZS 1067.1We offer a wide range of physical, mechanical, chemical &amp; performance tests to check the characteristics of your sunglasses, including: TransmittanceOptical PowerScattered LightMaterial &amp; Surface QualityMinimum RobustnessEnhanced RobustnessResistance to IgnitionResistance to RadiationEye Coverage and Field of ViewImpact ResistanceRefractive PropertiesSuitability for CleaningLens ColorUltraviolet Ray TransmissionPersonal Protective Equipment (PPE) testing and certification from SGS– ensure your products comply with Regulation, 2016/425.
