Import Cr-39,1.56 1.61 Hmc — Buy in Bulk from Supplier in China

CR-39 lenses in refractive indices 1.56 and 1.61 HMC are single-vision optical solutions designed for eyewear manufacturers seeking lightweight, impact-resistant materials. These lenses correct vision while maintaining a slim profile, with the 1.56 index offering a balance of thickness reduction and optical clarity, and the 1.61 index providing further thinning for higher prescriptions. The HMC (hard multicoat) finish enhances durability and reduces glare, making them suitable for daily wear applications.

The material composition of CR-39 is a thermosetting polymer, standard for optical lenses due to its scratch resistance and UV-blocking properties. Variants include tinted and coated options, such as anti-reflective and UV protection layers, which are typical for premium eyewear. The lenses are produced to standard optical tolerances, with surface quality and power accuracy meeting typical industry benchmarks for prescription lenses. Industry practice often includes a hardness test to verify scratch resistance, with CR-39 commonly achieving a Bayer value in the standard range of 3-4.

These lenses are primarily used in retail and wholesale eyewear markets, including safety glasses and sports eyewear, where impact resistance and comfort are critical. Buyers typically source them in bulk for frame assembly, with common trade terms including CIF and FOB from China. The supplier’s flexibility in MOQ allows stocking to match business scale, while compliance with certifications like ISO and CE ensures they meet international safety and quality standards for optical products.
