Kingway expands photochromic lens lineup across single vision, bifocal and progressive designs

Zhenjiang Kingway Optical is positioning its photochromic lens assortment around optical design first, then index, color and coating. The China-based factory says that structure helps wholesalers match single-vision, bifocal and progressive products to specific prescription and retail needs.

Why it matters: - Photochromic lenses are not one interchangeable category. Optical design, index and color all affect how wholesalers should buy, stock and dispense them. - Kingway is pitching a design-led sourcing model that can help distributors avoid mixing up single-vision, bifocal and progressive products in the same assortment. - The company says that clearer product routing can reduce RFQ errors, improve replenishment planning and better match clinical dispensing needs.

What happened: - Zhenjiang Kingway Optical Co., Ltd. outlined its photochromic lens range for wholesale buyers and importers. - The lineup includes single-vision, flat-top bifocal and progressive photochromic lenses. - The portfolio also includes 1.56 Photo Pink, Photo Green and Photogray options, plus 1.61 and 1.67 Spin Photogray products. - Kingway says the company was established in 2011. - The factory operates in China from a 5,000-square-meter facility and reaches daily output of 20,000 pairs.

The details: - Photochromic describes the light-responsive function of the lens, while single vision, bifocal and progressive describe the optical design. - Kingway says buyers should define the base lens geometry first, then add index, color, coating and quantity requirements. - The single-vision branch is positioned as the broadest entry family in the range. - Single-vision sourcing can be organized by refractive index and color after the physical design is set. - The company’s single-vision portfolio can be paired with Anti-Reflective (AR), Hard Multi-Coating (HMC) or Hard Coating (HC) requirements. - The bifocal option includes a 1.56 flat-top Photogray product. - The flat-top design gives users a visible near-vision segment for a segmented multifocal layout. - The progressive option includes a 1.56 progressive Photogray product. - Progressive sourcing requires corridor length, base curve, frame height, Addition (ADD) power and wearer history to be considered alongside the photochromic function. - Higher-index materials are presented as a thinner option for stronger prescriptions. - Kingway says spin coating on high-index lenses can support more uniform darkening and fading across lens thickness. - The broader portfolio also includes round-top and blended-top photochromic structures. - Kingway says it produces finished and semi-finished lens families, including single vision, flat-top, round-top, blended-top and progressive designs. - The company says buyers should specify optical design, index or material, photochromic treatment, prescription or stock requirement, coating, quantity and packaging needs in a wholesale RFQ. - Kingway says its offerings can be supplied with customized OEM envelopes. - The company directs buyers to its website for product matching and bulk order requests. - Kingway also links to its LinkedIn page.

Between the lines: - The release is as much about procurement workflow as it is about lenses. - By separating design, index and color into different buying fields, Kingway is signaling that wholesale buyers should treat photochromic lenses as layered SKUs rather than a single product bucket. - That approach favors chain-store buyers and Rx labs that need clean catalog structures and repeatable ordering rules.

What's next: - Kingway is steering importers and distributors to submit a photochromic matrix that matches the exact product route they want to source. - Buyers can expect future RFQs and replenishment orders to be easier to quote when optical design, index, treatment and packaging are listed separately. - The company is positioning its assortment for both catalogue planning and custom wholesale orders.
