What Crystal star does

Shenzhen Crystal-Star Technology Co., Ltd, trading as Crystal-Star, is a Shenzhen, China-based OEM manufacturer of polarized and specialty sun lenses founded in 2004. The company produces a broad lens portfolio — proprietary CSPL (laminated PC polarized), TAC, PC, Nylon/PA, and Eastman Tritan-based TR18/TR18RN lines — for eyewear brands, sunglass manufacturers, 3D cinema equipment producers (RealD/IMAX-compatible), and safety/protective eyewear makers. Manufacturing is conducted in GMP cleanrooms under ISO 9001 quality management with 20+ rigorous optical tests per lens, using imported raw materials and adhesives co-engineered with Eastman and Nippon Chemical.

Crystal-Star operates a pure B2B OEM/wholesale model: lenses are supplied in bulk under quote-based pricing that varies by material (CSPL/TAC/PC/Nylon/Tritan), thickness, color, and treatment, with no direct retail or consumer channel. Go-to-market relies on the company website, periodic news/content updates, and trade show participation (e.g., MIDO 2026 Milan), targeting enterprise buyers among premium and mid-market eyewear brands and equipment manufacturers globally. Triple regional certifications (Australia AS/NZS 1067, US ANSI Z80.3/Z87.1, Europe EN 166), ISO 14001, and ISCC PLUS support cross-border distribution and sustainability positioning.

The firm holds 31 patents and 8 software copyrights, has 21 years of industry tenure, and runs an R&D and production team sourced from Taiwan and Japan. It is privately held with no disclosed funding rounds, M&A activity, or revenue figures, and operates from a single headquarters and manufacturing site in the Yasen Innovation and Technology Industrial Park, Longgang District, Shenzhen.
