The importance of choosing safe sunglasses is often forgotten in the dizzying array of fun and fashion that surrounds sunglasses designs. 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.

Wenzhou Lynns Design Co. Limited

At JLX EYEWEAR, we've redefined what's possible in 3D printed eyewear finishing. Our proprietary post-processing technology transforms raw printed frames into luxurious wearable art, achieving a matte-shiny surface quality that sets new industry standards. These eight detailed close-ups reveal the meticulous craftsmanship behind every JLX EYEWEAR private label piece - notice how light dances across the perfectly balanced matte base while subtle luminous highlights accentuate each curve and contour.  Our multi-stage finishing process begins with precision mechanical polishing to eliminate all visible layer lines, followed by specialized chemical treatments that create the perfect matte foundation. The frames then undergo our signature coating application, where nano-level particles are carefully layered to build depth and dimension into the surface. The final hand-finishing stage ensures every millimeter meets our exacting standards, resulting in a tactile experience that feels as premium as traditional luxury materials.      What makes our finishing truly revolutionary is how it maintains structural integrity while achieving visual perfection. The matte surface provides sophisticated understatement, while the controlled shine adds dynamic energy that changes with movement and lighting. This proprietary technique allows for unprecedented consistency across entire collections - whether producing fifty or five hundred frames, each piece maintains identical surface characteristics.    For brands partnering with JLX EYEWEAR, this finishing technology opens new creative possibilities. Our process works seamlessly with complex geometric designs that would be impossible to finish conventionally, while offering customizable sheen levels from soft satin to high-contrast matte/gloss combinations. The result is eyewear that feels substantial yet lightweight, looks handcrafted yet technologically advanced.   Explore the future of 3D printed eyewear finishing at www.jeffreyleungeyeweardesign.com and discover how our surface technology can elevate your private label collection.  #JLXFinishing #MattePerfection#3DPrintedLuxury#EyewearInnovation#SurfaceTechnology#LuxuryFinishes#PrivateLabelExcellence#FutureOfEyewear
