Kingway highlights semi-finished lens lineup for Rx labs

Kingway says its China-based semi-finished lens offering now spans clear, photochromic gray and blue light blocking blanks across 1.56, 1.60 and 1.67 indices. The company is positioning the portfolio for distributors and Rx labs that need a more precise match between blank, optical design and downstream prescription processing.

Why it matters: - Rx labs and distributors need semi-finished blanks that match prescription design, index and functional treatment before surfacing begins. - A more specific blank matrix can reduce ordering errors, speed quotation review and improve downstream processing efficiency. - Kingway is pitching a structured sourcing model for wholesalers handling high-volume prescription lens orders.

What happened: - Kingway said its semi-finished lens portfolio covers clear, photochromic gray and blue light blocking variants. - The lineup spans 1.56, 1.60 and 1.67 index routes. - The portfolio includes single-vision, bifocal and progressive designs. - The company said the offering is aimed at B2B blank-lens sourcing for Rx labs, wholesalers, chain stores and international distributors. - Kingway identified itself as Zhenjiang Kingway Optical Co., Ltd. - The company said it was established in 2011. - Kingway directed buyers to its official platform at More information for quotation discussions. - Kingway also shared its LinkedIn page at Company social media.

The details: - A semi-finished blank is the intermediate optical substrate that still needs prescription surfacing before becoming a finished Rx lens. - Kingway said blank selection should start with the intended finished-lens design and prescription program. - Refractive index, optical design and functional treatment are separate specification fields in the sourcing process. - Photochromic blanks add light-responsive UV-activated behavior. - Blue light blocking blanks add wavelength-filtering for digital-use environments. - Clear blanks are positioned as the neutral route for standard vision correction. - The company said its custom-lens process uses computer-controlled cutting and grinding equipment. - The production flow can continue through polishing, ultrasonic cleaning, drying, optional tinting, hard coating, anti-reflective coating, laser marking, final inspection and frame assembly. - Kingway said finished and semi-finished lens families are both part of its global supply capability.

Between the lines: - Kingway is framing the product line as a technical sourcing system, not just a catalog of lens blanks. - The emphasis on three-layer specification suggests the company wants buyers to place more precise RFQs and avoid generic ordering language. - The message also positions functional treatments and optical design as separate decisions, which matters for labs trying to standardize inventory and production planning.

What's next: - Buyers can send blank matrix parameters and complete Rx-program requirements to request a quotation review through Kingway’s official site. - Rx labs and wholesalers using the lineup will still need to define index, design, function, quantity and processing route before production can begin. - The company’s semi-finished program will likely be evaluated on how cleanly it fits existing surfacing and coating workflows.
