Import Cr39 1.499,1.56 Round Top Bifocal — Buy in Bulk from Supplier in China

The CR39 1.499 and 1.56 Round Top Bifocal lenses from Danyang Xuzhi Optical Glasses Co., Ltd. are precision-manufactured using PPG/TS-46 material, a standard polymer for optical clarity and impact resistance. Available in diameters of 65mm and 70mm, these lenses are designed for bifocal applications where distinct near and distance vision zones are required. The Abbe values of 58 for 1.499 and 40 for 1.56 indices ensure minimal chromatic aberration, critical for high-prescription wearers.

These lenses feature a specific gravity of 1.32 for the 1.499 index and 1.28 for the 1.56 index, contributing to their lightweight design without compromising durability. They are offered with high scratch resistance and optional coatings, including super-hard protection (tintable and non-tintable), HMC, and HMC+EMI in greenish or bluish tints. Semi-finished or finished options are available, packaged in white bags (9x9x4.5mm), inner white boxes (30x9.5x9mm), and outer cartons (51x33x38cm). The lenses comply with CE and ISO standards, typical for export-grade optical products.
