Exhibition news | 25–28 September 2026 | Paris Nord Villepinte, Hall 6, Booth 6E017
HONGCHEN LENS presented its international B2B optical lens solutions at SILMO Paris 2026, held from 25 to 28 September at Paris Nord Villepinte, France. At Hall 6, Booth 6E017, the team met optical distributors, prescription laboratories, retailers and industry partners to discuss dependable stock lens supply, customized freeform RX lenses, progressive lens designs and streamlined prescription fulfillment.
The exhibition highlighted two complementary strengths: ready-to-ship stock lens solutions for commercial inventory planning, and a digital RX laboratory supporting individualized prescriptions and advanced lens design choices. The following overview explains HONGCHEN’s supply categories, RX production workflow and the named design families customers can ask about.

SILMO Paris 2026: A Meeting Point for International Optical Partners
Throughout the four-day exhibition, HONGCHEN exchanged practical information with visiting partners on refractive-index selection, coating preferences, progressive designs, prescription processing, delivery planning and OEM requirements. These conversations reflected the purchasing priorities of professional optical buyers: consistent specifications, reliable communication, manageable lead times and solutions suited to different wearer needs.
For buyers evaluating a long-term optical lens manufacturer in China, HONGCHEN offers both high-volume stock lens manufacturing and more specialized freeform RX services. The two supply models can be combined to support optical wholesalers, independent practices, chain stores and professional laboratories.
Optical professionals discussing product requirements at HONGCHEN's booth.
1. Stock Lens Supply: A Complete Range for B2B Optical Buyers
Stock lenses are finished ophthalmic lenses supplied in commonly requested prescriptions, diameters, materials and coatings. For distributors and optical retailers, a dependable stock program can help reduce procurement complexity and support routine replenishment. At SILMO, HONGCHEN presented a stock lens portfolio covering conventional everyday prescriptions and selected specialty functions.
Stock Lens Materials and Refractive Indices
| Material / index | Typical sourcing consideration |
| CR-39 / 1.50 class | Established material category for standard clear and coated single-vision lenses. |
| 1.56 | Mainstream value-focused stock lens programs, including clear and selected functional options. |
| 1.61 MR-8 | Higher-index option for buyers seeking a thinner-lens product tier. |
| 1.67 / 1.71 / 1.74 | Higher-index categories used in stronger prescriptions and premium product assortments. |
| Polycarbonate (PC) | Impact-resistant material category for selected safety, sports and prescription uses. |
Availability varies by prescription range, diameter, coating and lens design. Customers should request a current SKU list rather than assume that every combination is stocked.
Stock Lens Product Categories
| Product category | B2B applications and buyer questions |
| Single Vision Stock Lenses | Everyday distance or near corrections; ask about index, power range, diameter, coating and minimum order. |
| Progressive Stock Lenses | Ready-made multifocal options for specific markets; confirm corridor design and available additions. |
| Blue Cut / Blue-Light-Filtering Lenses | Selected material and coating options with defined optical filtering characteristics; request product specifications. |
| Photochromic Lenses | Clearer indoors and darker outdoors under suitable UV/light conditions; confirm color and activation technology. |
| Polarized and Sun Lenses | Glare-control and sunwear-related categories where available; confirm lens substrate and intended application. |
| Bifocal and Semi-Finished Lenses | Selected multifocal and further-processing options for customers operating their own laboratories. |
HONGCHEN supports OEM and private-label discussions for qualifying commercial orders, including packaging and assortment coordination. Lead times, stock commitments, test requirements and branding specifications are reviewed by product and market.
Why Stock Lens Buyers Discuss Supply Reliability
Beyond a price list, distributors commonly need stable refractive-index ranges, traceable model specifications, repeatable coatings, clear packing information and predictable dispatch planning. HONGCHEN's stock lens service is intended to help partners structure purchasing by materials, lens functions and market tiers instead of selecting individual products without an inventory plan.
The stock lens section highlighted broad product coverage and supply support.
2. Freeform RX Lens Solutions: From Digital Design to Lab Production
Freeform RX (prescription) lenses are calculated and processed for a wearer's individual prescription and, where relevant, additional fitting or position-of-wear parameters. Compared with standard stock lenses, customized freeform production can support more complex prescriptions and specialized designs, including progressive, office/occupational, digital single-vision and special-use lenses.
At SILMO Paris 2026, HONGCHEN presented its 48-hour RX service capability alongside customized freeform design options. "48 hours" refers to a fast laboratory production/turnaround target for qualifying RX orders after all required information is confirmed; it is not a guarantee of international door-to-door shipping within 48 hours. Product complexity, materials, coating, prescription and current capacity affect the quoted turnaround.
The exhibition featured freeform RX and stock lens solutions.
Inside the Digital RX Lab: Machinery and Workflow
The RX process begins with prescription validation and order checks. The lens design is selected and calculated, and the laboratory proceeds with freeform surfacing, polishing, coating and quality verification as applicable. For partners needing finished eyewear solutions, edging, remote cutting and assembly can be discussed as additional services subject to frame data and feasibility.
The HONGCHEN laboratory equipment information includes Satisloh VFT-orbit-2i surfacing and Multi-FLEX-2 polishing equipment. These machines support precision freeform lens processing as part of the overall workflow. The suitability of any design still depends on prescription parameters, substrate, coating and final laboratory validation.
Digital RX laboratory equipment: Satisloh Multi-FLEX-2 and VFT-orbit series.
| Lab stage | What it means for an optical B2B buyer |
| Prescription and order review | Check sphere, cylinder, axis, addition, prism, PD/centration and other required input data. |
| Digital lens design calculation | Select a design suited to daily distance, progressive, computer/office or special visual tasks. |
| Freeform surfacing and polishing | Machine the calculated prescription surface with controlled processing steps. |
| Coating, inspection and verification | Check the order against agreed technical specifications and quality procedures. |
| Optional edging / remote cutting / assembly | Discuss frame-trace data, fitting responsibility, logistics and lead time before placing orders. |
3. Three RX Design Portfolios: OptoTech, IOT and Horizons Optical
A lens design platform should not be confused with a single finished-lens product. At SILMO, discussions covered three groups of named freeform design references—OptoTech OptoCalc 4.0, IOT's Camber/Endless solutions and Horizons Optical's design portfolio including Maxview. These third-party names identify the underlying design families; individual HONGCHEN order availability, country rights, combinations and processing capability must be confirmed by the RX team before quoting.
EXPLORE EACH DESIGN IN DETAIL: Freeform RX Lens Designs — OptoTech 4K, IOT Endless & Horizons Optical. Read the full model-by-model guide, its advantages, working-distance classifications and supplier catalogue references. (Link activates only once the permanent page is published.)
A. OptoTech OptoCalc 4.0 / 4K Freeform Designs
OptoTech's OptoCalc 4.0 catalogue distinguishes OptoDesign Pro (ODP), high-resolution 4K optimization and OptoTech Minimal Distortion (OMD). The catalogue includes standard ECO progressives, 4K Comfort progressives, OMD Comfort Pro designs and task-specific lifestyle lenses. "4K" describes a lens-design optimization technology in the referenced catalogue; it is not the name of every OptoTech design.

Important technical distinction: OptoTech 4K is an optimization technology; ECO, Comfort and Comfort Pro are separately named design families. The catalogue associates its premium Comfort series with 4K and its high-end Comfort Pro series with ODP, 4K and OMD. Do not label every OptoTech design a "4K lens".
Buyers searching for "OptoTech 4K progressive lens", "OptoTech Balanced Comfort Pro" or "OptoTech Office Relax" can use these exact catalogue terms when requesting a recommendation. The RX team can evaluate the required prescription, fitting height, corridor and material before confirming a suitable option.
