Import Cr 39 1.499 S/F Progressive Optical Lens — Buy in Bulk from Supplier in China

The Cr 39 1.499 semi-finished progressive optical lens from EXIA Glasses Co.,Ltd. is a resin-based lens with a refractive index of 1.499, designed for progressive power correction. It is available in diameters of 65 mm and 70 mm, with an Abbe value of 58 for minimal chromatic dispersion. The lens achieves light transmission exceeding 98%, ensuring clarity, and offers abrasion resistance rated at 6 to 8 hours under standard testing, making it suitable for prolonged use in prescription eyewear.

Made from CR-39, a lightweight and impact-resistant polymer, this lens is available in progressive, round-top bifocal, and flat-top bifocal configurations. The material is a standard in the optical industry for its balance of optical performance, durability, and cost-efficiency. Typical applications include everyday prescription glasses, where the lens’s high transmission and scratch resistance provide long-term reliability. The semi-finished state allows for further customisation by optical labs to match specific prescriptions.

These lenses are supplied in bulk packaging: 5 pairs per box (20 x 10 x 8.5 cm) and 21 boxes per carton (44 x 32 x 24.5 cm), or as per buyer specifications. Progressive lenses are commonly used by opticians and eyewear manufacturers targeting consumers with presbyopia or multifocal vision needs. Buyers should confirm the exact power range, edge thickness, and base curve compatibility with their frame designs before ordering.
