How a large-scale stock-lens manufacturing base is being extended into integrated digital freeform RX production for global B2B customers

HONGCHEN Optical (JIANGSU HONGCHEN OPTICAL CO., LTD.) has built its business over nearly 40 years on large-scale finished and semi-finished stock lens manufacturing. That stock business remains the foundation of the company in 2026. The major development is the continued expansion of an integrated digital RX platform alongside it: freeform generation, automated polishing, a broader range of customized prescription designs, and faster turnaround for standard RX orders.

For distributors, optical chains, online eyewear businesses, and RX labs, the significance is not that HONGCHEN has moved away from stock lenses. It is that the same manufacturing base can now support both high-volume standard products and more specialized prescription work, reducing the need to coordinate unrelated suppliers.

The Foundation: Established Stock-Lens Manufacturing

HONGCHEN Optical’s core business has long been finished and semi-finished stock lens production at scale. The operating model is supported by substantial warehousing capacity, broad inventory across common materials and power ranges, automated production and coating lines, and standardized quality-control procedures.

This stock manufacturing base is important to the company’s RX development because the RX laboratory is not a separate, disconnected operation. Customized prescription production can draw on the same material supply, coating infrastructure, warehousing, and quality-management framework that support the high-volume stock business.

Growing Digital RX Capability: Generation, Polishing, and Freeform Design

The 2026 RX platform is built around multiple digital-processing technologies rather than a single machine. HONGCHEN Optical operates three Schneider HSC Modulo ONE high-speed freeform generators, Satisloh VFT-orbit-2i digital generating equipment, and Multi-FLEX-2 fully automated polishing systems.

The HSC Modulo ONE and VFT-orbit-2i provide complementary digital generating capacity rather than consecutive processing steps. After digital generation, Multi-FLEX-2 supports automated polishing across different RX geometries and lens diameters. This equipment mix gives the laboratory greater flexibility across prescription ranges, lens materials, and design requirements.

Freeform production shapes the customized lens surface from digital design data instead of relying only on a fixed physical mold or a single preset geometry. Depending on the selected progressive design and the fitting data available for the order, calculations may incorporate parameters such as vertex distance, pantoscopic tilt, and frame wrap angle. These are design- and order-specific capabilities; they are not automatically applied to every standard progressive order.

Standard RX orders can be completed in as little as 48 hours from HONGCHEN Optical’s Danyang production base, depending on lens material, design, coating, prescription complexity, and order confirmation.

Selected RX Equipment Roles

Where Stock and RX Come Together

For a distributor or optical chain, the practical advantage of HONGCHEN Optical’s current model is the ability to source stock and customized RX lenses from the same manufacturing group. High-volume standard prescriptions can be supplied from finished-stock programs, while powers, designs, or combinations outside the available stock range can move into custom RX production.

This reduces the operational gap between everyday replenishment and specialized prescriptions. A buyer can coordinate standard single-vision and progressive stock programs alongside customized single vision, freeform progressive, office/occupational, high-index, photochromic, polarized, and other RX requirements without building a completely separate supplier structure.

The value is not only convenience. Shared material sourcing, coating systems, quality procedures, warehousing, and account coordination can also help maintain a more consistent product and service experience across the buyer’s stock and RX programs.

Material and Design Combinations

HONGCHEN Optical’s RX development is also broadening the combinations buyers can specify rather than focusing on a single progressive design. Available programs can combine different lens indices with freeform single-vision, progressive, office/occupational, photochromic, polarized, and blue-light-filtering configurations according to the selected material and design.

For example, selected progressive products can combine photochromic performance with HMC or SHMC coating options, while other RX programs can combine high-index materials with blue-light-filtering or polarized functionality. Because design availability, power range, diameter, coating, and material compatibility differ by specification, buyers should confirm the current technical chart for the exact combination required.

The important development for B2B customers is the move from a catalog dominated by standard stock SKUs toward a broader manufacturing platform that can handle both repeat-volume products and more individualized prescription configurations.

Production Discipline: Coating Consistency, QC, and Turnaround

Advanced RX capability depends on more than surfacing equipment. Customized lenses still require stable coating processes, prescription verification, surface-quality inspection, and controlled order handling. HONGCHEN Optical’s RX production uses the same broader quality-management framework that supports its stock-lens business.

Optical power, cylinder axis, addition, and surface quality are inspected according to established quality-control procedures. Automated coating lines, standardized process controls, and batch inspections also support more consistent AR reflection color and surface appearance across repeat-order programs.

For international buyers, the most useful way to evaluate RX capability is therefore to look at the entire production system: design coverage, generating and polishing equipment, coating control, quality verification, turnaround policy, and the supplier’s ability to support repeat orders over time.

Trade Show Presence in 2026: Bringing Stock and RX Together for Buyers

HONGCHEN Optical has used international optical exhibitions, including MIDO in Milan, as opportunities for buyers to review products and discuss supply programs in person. In 2026, the company’s expanding RX capability is becoming a more visible part of that international presentation rather than remaining a back-end production service.

HONGCHEN Optical will exhibit at SILMO Paris from 25 to 28 September 2026 at Paris Nord Villepinte, booth 6E015, near the SILMO Talks area. The exhibition gives distributors, optical chains, online eyewear businesses, and RX partners an opportunity to discuss current stock-lens programs, freeform RX designs, materials, coating options, turnaround expectations, and trial-order arrangements directly with the team.

Conclusion: A Stock-Lens Manufacturer Building a Broader RX Platform

HONGCHEN Optical’s 2026 development is best understood as an expansion of an established manufacturing base. The company remains a large-scale stock-lens manufacturer, while digital freeform generation, automated polishing, broader design coverage, and faster RX turnaround are extending what the same production platform can offer international B2B customers.

HONGCHEN Optical supports distributors, optical chains, online eyewear businesses, and RX labs with an ISO 13485 quality management system, current FDA registration, organized CE documentation, finished-stock capacity, automated coating capability, and an integrated RX production base in Danyang, Jiangsu.
