Koc Lens
Overview
Product sourcing insights & recommendations
The term "KOC Lens" refers to a specific category of optical resin materials developed by ML Tech, a South Korean subsidiary of Mitsui Chemicals SelectopticallensMitsuichemicals. Positioned as a high-durability, cost-effective alternative to the premium MR™ series, KOC lenses are widely used in the Asian market for sports, children's, and safety eyewear due to their "bulletproof" impact resistance Selectopticallens.
Core Product & Market Insights
* Material Composition & Tech: KOC lenses are primarily polyurethane-based optical resins, distinct from the thiourethane-based MR series Selectopticallens. They typically feature a middle refractive index of 1.55 to 1.56 and a moderate Abbe value of 33–36, which balances thinness with physical toughness PolopticSelectopticallens.
* Key Market Trends (2025-2026): The market is shifting toward specialty functional lenses. The KR™ variant is gaining momentum for its integrated blue light blocking (UV420) and enhanced UV protection, catering to the growing "digital eye strain" segment SelectopticallensFacebook.
* Target Segments: Due to their extreme durability, these lenses are the preferred choice for activewear and pediatric optics Selectopticallens. In the B2B sector, they are increasingly paired with aspheric (ASP) designs and multi-coatings (HMC/AR) to compete with higher-index materials on performance Alibaba.
B2B Market Landscape
The B2B market for KOC lenses is highly concentrated in Danyang and Zhenjiang, China, which serve as global manufacturing hubs for these materials.
* Pricing: Wholesale prices are highly competitive, typically ranging from $0.50 to $2.00 per pair depending on the refractive index (1.56 vs 1.61) and coating options .
* Availability: Suppliers frequently offer 1.61 ASP KOC materials to provide a thinner profile that mimics premium 1.60 MR-8 lenses at a lower price point AlibabaAlibaba.
