Import Cr-39 Polarized Lens — Buy in Bulk from Supplier in China

The Cr-39 polarized lens from Tongyi Optical is a lightweight, durable optical component designed for glare reduction and UV protection. Made from Columbia Resin #39, a thermosetting plastic known for its clarity and impact resistance, this lens integrates a polarized film that blocks horizontal light waves, cutting reflected glare by up to 99 percent while maintaining color fidelity. The base material’s Abbe number of 58 ensures minimal chromatic aberration, making it suitable for precision eyewear.

Standard Cr-39 lenses offer a refractive index of 1.498 and a typical density of 1.32 g/cm³, providing a balance between thinness and optical performance. Tongyi Optical’s version includes a hard coating for scratch resistance and an anti-reflective layer on the back surface to reduce internal reflections. The lens is available in common base curves of 4 to 8, with a typical center thickness of 1.2 mm for single-vision applications. Industry standards for polarized lenses also require a transmittance of visible light between 15 and 25 percent, depending on tint intensity.

These lenses are primarily used in prescription and non-prescription sunglasses, safety eyewear, and sports optics where glare reduction is critical. Buyers include eyewear manufacturers, optical labs, and industrial safety suppliers. For bulk trade, confirm packaging options such as individual poly bags or tray-based bulk shipping, as well as compliance with regional UV protection standards like EN 1836 or ANSI Z80.3. Lead times and MOQs vary by order size and should be verified directly with Tongyi Optical.
