We don't just produce eyewear; we engineer it. SnowLux operates a fully equipped R&D facility in Wenzhou, China, spanning 2,500 square meters and housing three dedicated research wings: Frame & Materials Engineering, Lens Technology, and Optical Metrology.
Our team works closely with international partners — including lens coating suppliers from Germany, acetate material experts from Italy, and hinge manufacturers from Japan — to keep SnowLux at the cutting edge of eyewear innovation.
From TR90 and titanium to acetate and ultem — we research and test every material in our frame portfolio. Our materials lab performs tensile strength tests, UV aging simulations, and skin-contact safety verification for every material batch.
We develop and test polarized, photochromic, blue-light blocking, and anti-fog lenses in-house. Our lens lab is equipped with automated transmittance meters, UV spectrometers, and haze measurement stations — ensuring every lens meets ANSI Z80.3 and ISO 8980 standards.
Precision measurement is at our core. We operate automatic lensometers, spectrometers, spherical meters, and optical distortion testers. Our metrology team certifies every production mold and lens curve against the master CAD specifications before tooling approval.
Our design team combines CAD/CAM modeling with a growing 3D facial scan database to optimize frame fit across diverse face shapes. We develop original form designs, temple curves, and nose pad geometries for maximum wearing comfort.
Universal testing machine, UV weathering chamber, salt-spray corrosion tester, and thermal shock chamber for frame and component durability.
UV-VIS spectrophotometer, lensometer, haze meter, and polarizing efficiency tester — fully compliant with ISO and ANSI optical standards.
CNC milling center (5-axis) and SLA/SLS 3D printers producing concept samples and test jigs within 24-48 hours of design approval.
Automated frame flex testers, hinge fatigue machines, and abrasion rollers simulating 12+ months of daily use in accelerated conditions.
Vacuum coating equipment, hard-coat dipping line, anti-reflection deposition system, and oleophobic top-coat spray for custom surface treatments.
Spectrophotometer, gloss meter, and RAL/Pantone-matched color mixing station enabling precise batch-to-batch color consistency across all frame finishes.
Developed a proprietary TR90 formula reducing frame weight by 22% while maintaining full flex-recovery performance. Combined with spring-loaded temples for universal fit.
Engineered a multi-layer polarized lens stack with enhanced scratch resistance (8H pencil hardness) and hydrophobic oleophobic coating. Achieved 99.6% UV400 blockage.
Patented a blue-light selective absorption coating technology that filters 40% of harmful blue-violet light (400-445nm) while maintaining neutral color perception.
Designed a patented magnetic clip-on mechanism that snaps to existing optical frames without visible hardware, enabling seamless sunglass-to-optical transitions.
Set an internal durability benchmark of 50,000+ flex cycles (vs. industry standard 10,000) after extensive hinge fatigue testing across titanium and stainless steel spring variants.
Developed a dual-side hydrophilic anti-fog coating technology suitable for cycling and sport eyewear. Treated lenses maintain clarity across temperature swings of -10°C to +40°C.
