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

The CR-39 lens offered by Tongyi Optical is a polymer optical element sized for common frame designs. It is supplied in diameters of 60 mm, 65 mm or 70 mm and covers a spherical power range from 0.00 to - 6.00 diopters. The lens blank measures 47 × 34 × 30 mm and is made from CR‑39 material that provides inherent UV protection and impact resistance.

CR‑39 is a standard plastic used in single‑vision and lightweight multifocal applications. Typical refractive index for the material is 1.498 and the Abbe value is around 58, giving good colour fidelity. Industry practice adds a hard coating that gives scratch resistance comparable to mineral glass, and many manufacturers apply anti‑reflective or photochromic layers as optional finishes. The material’s density is roughly 1.30 g cm‑3, which translates to a lightweight finished lens.

Optical manufacturers, retail chains and independent opticians source this lens for prescription glasses, fashion frames and safety eyewear. Tongyi Optical lists flexible trade terms such as L/C or T/T, but exact minimum order quantities and lead times are not disclosed in the public data.
