Eyebeauty Technology Co., Ltd. operates two enterprise manufacturing hubs combining 40+ years of heritage, Class 100,000 cleanrooms, and stringent medical device certifications under CE (MDR), ISO 13485, and FDA regulations.
ESTABLISHED 1984
As the founding base of our manufacturing group, Gansu Constar Technology Group carries over four decades of mastery in optical engineering and soft contact lens production. Equipping high-precision automated lathe cutting lines alongside high-speed cast molding systems, it serves as the benchmark facility for medical-grade vision correction and high-water-content daily lenses.
LIANGGUO GROUP
Hunan Haipuming Technology serves as our specialized color and cosmetic contact lens innovation center. Featuring modern Class 100,000 cleanrooms and multi-layer sandwich pigment lock technology, this base safely seals biocompatible pigments between lens polymers to prevent ocular contact while delivering hyper-realistic color depth and K-beauty glow aesthetics.
From raw polymer synthesis to automated packaging, our integrated production chain ensures end-to-end traceability and medical device reliability for overseas private labels.
Pigment layers are completely encapsulated inside lens hydrogel polymers. Color pigments never touch the cornea or palpebral conjunctiva, guaranteeing zero dye leaching and maximum ocular health.
Automated injection molding and curing are executed in strict ISO-compliant Class 100,000 environments with positive pressure HEPA filtration, ensuring pristine, particulate-free lens surfaces.
Terminal sterilization is conducted with validated industrial high-pressure steam autoclaves at 121°C, securing Sterility Assurance Level (SAL) 10^-6 across every blister and vial batch.
High-resolution CCD vision systems and digital polariscopes inspect 100% of manufactured lenses for edge chips, air bubbles, center thickness variations, and printing concentricity.
We supply full technical files for target market approvals, including MFDS (Korea), CE MDR (Europe), and FDA 510(k), comprising biocompatibility reports (ISO 10993) and accelerated stability studies.
Flexible production lines support custom blister sealing foils, secondary carton printing, barcoding (UDI compliance), and tailored replacement schedules spanning daily, monthly, and yearly cycles.
Our laboratories implement rigid batch-by-batch QA testing conforming to international medical device directives.
Every batch verifies dioptric power, base curve radii, and center thickness via high-precision focalimeters.
Microbiological monitoring and endotoxin testing guarantee zero post-market contamination risk.
Cytotoxicity, ocular irritation, and systemic toxicity tests certified by international GLP laboratories.
Continuous refinement since 1984 ensures rapid cycle times, low scrap rates, and stable bulk supply.
