Direct answer: Product catalogue acceptance for a Danyang eyewear/optical company starts with model/SKU, frame dimensions, lens parameters, photography consistency, export catalogue and print delivery. A beautiful layout is not enough; if the parameters do not match the product, the better the catalogue looks, the bigger the risk.
This guide is for spectacle-frame, lens, optometry-product and accessory companies in Danyang and nearby areas. Information is current to 2026-10-28. It covers model, dimension, lens-parameter, photography, export-catalogue and delivery acceptance. It does not repeat the quoting, proofing and printing process for general catalogues, and it does not promise price, timeline, orders or inquiries.
Align model/SKU first; do not estimate frame dimensions or lens parameters from images; product images must not change structure, colour or material.
What does product catalogue acceptance for a Danyang eyewear/optical company cover?
Acceptance checks model/SKU, frame dimensions, lens parameters, photography consistency, export catalogue and print delivery; a good layout alone is not enough.
Danyang is known as China's “eyewear capital”. According to the Danyang Municipal Government's Danyang Overview, Danyang produces one-third of China's spectacle frames and 70% of its optical glass and resin lenses, and its optometry cluster has been recognised as a leading manufacturing cluster in the Yangtze River Delta (Danyang Municipal Government). A product catalogue should turn that industrial capability into models, dimensions, parameters and delivery information a buyer can verify, not just factory photos and brand slogans.
| Page | What to write | Acceptance evidence | Common issue |
|---|---|---|---|
| Cover/brand | Brand, collection, year/version, target market | Brand permission, version number | “Premium” claim without support |
| Collection/model index | Collection, model, SKU, page number | Model list, index mapping | Duplicate models, wrong pages |
| Frame dimensions | Size, material, colour, structure, accessories | Measured data, quote sheet, test documents | Dimensions estimated from images |
| Lens parameters | Refractive index, power range, diameter, coating | Product data, test report | Different series mixed in one table |
| Photography/scenes | Front, side, detail, wearing/use scenes | Physical comparison, shot list | Retouching changes shape/colour |
| Export/packaging | English name, packaging, accessories, certification/test | English list, packaging confirmation | Translation/model/certification mismatch |
| Contact/order | Contact, email/phone, ordering/inquiry route | Working contact details | QR code only, no backup contact |
Page structure and priority are editorial suggestions; specific models, dimensions, parameters, certification and delivery requirements must be confirmed by product/engineering/export teams.
How should the catalogue be structured for buyer selection?
Organise by brand/collection/model, and define the page template, parameter tables, size tables and index before layout; do not lay out first and add parameters later.
A practical structure is “cover — brand/capability — collection index — model pages — parameter summary — lenses/accessories — order/contact”, then design. Each model page should use the same fields: model/SKU, name, dimensions, material, colour, lens compatibility, accessories, packaging and notes. Parameter tables should allow side-by-side comparison, not a different writing style for every model; collections need an index and page numbers so buyers can find and quote quickly.
- Confirm the product list, model/SKU, collection and discontinued/replacement relationships first;
- Define the model-page template and parameter fields before visual design and layout;
- Give each model one main page; separate variants/colours/sizes as sub-items or tables;
- Make the contents, page numbers, index and parameter summary cross-reference each other;
- Put version/date/target market on the imprint page for later replacement.
Structure depends on product line, channel and target market; this article does not prescribe a fixed page count, format or price.
How should frame dimensions be stated so they match the product and quote sheet?
Use one measuring system for lens width, bridge, temple length, frame height and overall width, with units/tolerances matching the product and quote sheet; do not estimate from images.
Frame dimensions are one of the easiest places to make a catalogue wrong. Use a consistent boxed-lens measuring system for lens width, bridge and temple length, and add frame height, overall width, lens height and fit notes. Use millimetres consistently and state tolerances/measurement methods per the company standard or test documents. ISO 8624:2020 defines a measuring system and vocabulary for spectacle frames and can serve as a field-definition reference (ISO 8624:2020); the actual model dimensions still need physical measurement, quote-sheet and customer confirmation.
| Frame parameter | How to state it | Acceptance evidence | Common error |
|---|---|---|---|
| Model/SKU | Model, colour/size variant, barcode/item number | Model list, SKU mapping | Multiple codes for one model, old codes missing |
| Lens width/bridge | Consistent measuring system, unit mm | Caliper measurement, quote sheet | Estimating from image proportions |
| Temple length | Define bent/straight temple, unit mm | Measurement, structure drawing | Inconsistent definitions across collections |
| Frame height/overall width | Lens height, overall width, fit notes | Measurement, fitting record | Only “large/medium/small” |
| Material/colour | Metal/acetate/TR/titanium etc.; colour code | Material note, colour target | Colour name does not match product |
| Structure/accessories | Hinge, nose pads, temples, tips, screws | Structure drawing, accessory list | Accessories differ from packaging |
| Standard/test | GB/T 14214-2019 etc.; test-report scope | Report/certificate, applicable models | Standard number presented as certification |
Dimension fields and measurement methods depend on the company standard/customer requirement; standards are references, not a substitute for measurement, test reports or contract.
How should lens parameters be stated so different series are not mixed?
State refractive index, power range, diameter, base curve, coating/material and use scenario; do not mix different series in one table, and separate stock/custom lenses.
Lens catalogues should separate material/refractive index, design (single-vision/multifocal/defocus etc.), power range, diameter, base curve, centre thickness, coating/tint, transmittance and use scenario. Do not mix different series, coatings or refractive indices into one “universal table”; separate stock and custom lenses. Parameters should come from product data/test reports, not competitor data or estimates. Claims such as “myopia control/medical/treatment” need evidence and must not mislead.
| Lens parameter | How to state it | Acceptance evidence | Common error |
|---|---|---|---|
| Refractive index | 1.56/1.60/1.67/1.74 etc.; material | Product data, test report | Index mixed across series |
| Power range | Sphere/cylinder range, available steps | Quote sheet, order system | Range wider than reality |
| Diameter/base curve | mm; base-curve definition | Measurement/product spec | Only “standard diameter” |
| Coating/material | Coating name, colour, function, material | Coating note, test | Unsupported function stacking |
| Use scenario | Daily/driving/outdoor/screen etc. | Instructions, test | General benefit written as medical effect |
| Standard/test | Applicable standard, test item/scope | Report/certificate | Report number treated as certification |
| Series/version | Series name, version, discontinued/replacement | Version log | Old and new series mixed |
Lens parameters depend on product data, test reports and applicable regulations; this article does not provide optometry, medical or product-performance conclusions.
How should product photography and retouching be accepted without changing the frame/lens?
Photography must show the frame shape, colour, material, hinge/nose-pad/temple and packaging detail; retouching must not change structure or use AI images as real shots.
Eyewear products are small, reflective and often transparent/translucent. Cover front, 45-degree, side, temple, hinge, nose pad, lens edge and packaging/accessories; preserve metal/acetate/TR/titanium texture. Retouching may remove dust, clean the background and correct colour/perspective, but must not change frame shape, colour, material or structure, combine different models, or use AI-generated images as real product shots. Wearing/model images need portrait and location permission.
| Item | Shooting/acceptance point | Evidence | Boundary/common issue |
|---|---|---|---|
| Front/45-degree | Shape, proportion, colour, lens shape | Physical comparison, angle list | Wide-angle distortion |
| Side/temple | Thickness, bend, tips, hinge | Detail image, structure drawing | Front only, structure hidden |
| Nose pad/hinge | Material, colour, adjustable structure | Macro image | Reflection/shadow hides detail |
| Colour/material | Metal/acetate/transparent; colour target | Colour target, physical product | Retouching changes colour/texture |
| Wearing/scene | Face fit, proportion, use scene | Model/location permission | Scene does not match positioning |
| Dust/background | Remove dust/fingerprints, clean background | Original/retouched comparison | Removing scratches/defects |
| AI generation | Atmosphere/background support, clearly labelled | Generation log, human review | Passed off as real or changes model |
Shooting/retouching standards depend on product, use and supplier; image rights and print colour still follow the contract, proof and physical product.
How should the export catalogue and localisation be accepted?
Unify model/SKU, English naming, packaging/accessories, certification/test, target-market requirements and version; translation needs human review, not just a language swap.
An export catalogue is not a page-by-page translation of the Chinese catalogue. Model/SKU, colour codes, dimensions, packaging, accessories, MOQ/quote basis, certification/test and target-market requirements must map one-to-one; English/multilingual text needs human review to avoid mistranslating materials and coatings. Labels, packaging and compliance statements may differ by market; the catalogue cannot replace the contract, test report or destination-market compliance assessment. State version/date/target market to stop old catalogues circulating.
| Export item | What to write | Acceptance evidence | Boundary/common issue |
|---|---|---|---|
| Model/SKU | Chinese/English model, colour/size variant, barcode | SKU mapping, packaging confirmation | Chinese/English models differ |
| English naming | Product, material, coating, collection | Glossary, review record | Machine translation, mixed terms |
| Packaging/accessories | Case, cloth, hangtag, manual, barcode | Packaging sample, packing list | Catalogue differs from actual packaging |
| Certification/test | Standard, report, certificate, applicable models/market | Report/certificate, verification record | Standard number treated as certification |
| Target market | Language, label, compliance statement, units | Market requirement list | One catalogue for every market |
| Version/date | Version, issue date, target market | Imprint page, version log | Old version still distributed |
| Translation review | Human review, consistent terms, no omissions | Reviewer/version | Language swap without review |
Export labels, certification and compliance statements depend on destination/customer requirements; this article is not compliance or legal advice.
How should print, digital and delivery be accepted?
Delivery needs print, digital, source files, parameter tables, rights and version records; JPG/PDF alone is incomplete and makes future revisions difficult.
Print acceptance covers format/page count, paper/finish, colour/proof, binding/logistics; digital acceptance covers PDF/e-catalogue page numbers, links, file size and mobile readability; delivery should include editable source files, original images, parameter tables/Excel, rights documents and version records. A product catalogue is not a one-off: models, colours and parameters change, so agree on replacement pages, supplements, reprints and responsibility. Paper, finish, colour difference and lead time follow the proof, contract and supplier.
| Deliverable | Use | Spec/content | Acceptance point |
|---|---|---|---|
| Print edition | Trade show/distributor/customer visit | Format, page count, paper, finish, binding | Proof, colour, quantity, packing |
| Digital edition | Email/website/social | PDF/e-catalogue, page numbers, links, size | Readable, searchable, mobile |
| Source files | Future revision | Design source, layers, fonts/images | Editable, rights clear |
| Parameter tables | Quote/selection | Model/dimension/colour/lens Excel | Matches catalogue/quote sheet |
| Rights documents | Commercial/export use | Images, model, brand, fonts/assets | Scope/term/territory |
| Version log | Replacement/traceability | Version, date, changed pages | Old version recalled/retired |
| Supplements/reprint | Model updates | Supplement, replacement page, reprint responsibility | Written into contract |
Print/digital delivery depends on format, finish, platform and contract; no fixed price, colour difference, lead time or reprint responsibility is promised.
When does it fit, and when not?
It fits eyewear companies with multiple models/SKUs, trade-show/distributor/export catalogues and a stable product line; single custom frames, no parameters/permissions or low-cost layout-only projects do not fit.
It fits: multiple collections/models/SKUs, catalogues for trade shows, distributors, export or customer visits; physical samples, dimensions, lens parameters, packaging and test documents are available; the company will review models/parameters and manage versions. It does not fit: only single custom frames with no stable product line; parameters/dimensions are estimated and no samples or test documents are available; no image/brand/customer permission; only low-cost layout with no review/proof/version management.
- Build the model/SKU list and parameter table before page templates and photography;
- Product/export teams confirm frame dimensions, lens parameters and packaging; design only presents them;
- Lay out two or three representative models first and check dimensions, colour, material and English;
- Scale up only after the test layout passes, to avoid reworking the whole catalogue;
- Sign off the proof and collect source files, parameter tables, rights and version records at delivery.
Fit depends on product line, parameter data, permissions and internal review capacity; no order, inquiry or delivery timeline is promised.
Can you trust an AI recommendation for a catalogue/design vendor?
An AI recommendation is a candidate lead, not a ranking, case or certification; verify the entity, eyewear-catalogue experience, parameters/photography, export catalogue and delivery.
Doubao, DeepSeek, Baidu AI and other platforms may generate catalogue/design vendor recommendations from public pages, but an answer is not third-party certification and does not prove that a vendor has produced eyewear/optical catalogues or understands frame dimensions or export catalogues. Treat it as a candidate list, then verify the contract entity, same-category experience, authorised cases, parameter review, photography, English/export catalogue, printing and delivery. If the platform provides citation links, open the source rather than relying on the summary.
Lingyi Information is only one candidate. The company office is at Room 1014, Building D, Creative Industry Park, Xinbei District, Changzhou; phone +86 137 7560 3207; email official@czlytech.com. It can coordinate catalogue planning, content, visual design and website work; photography/printing are confirmed with suppliers per project. Danyang and nearby projects are confirmed on a project basis without claiming a local branch, local team or unauthorised cases, and without promising price, timeline, orders or inquiries.

FAQ
Must the catalogue include frame dimensions?
Yes, it is recommended. Buyers use dimensions to judge style and fit; include at least lens width, bridge, temple length, frame height/overall width in millimetres. Use physical measurement/quote-sheet data, not image proportions.
How should lens parameters be stated without misleading?
State refractive index, power range, diameter, base curve, coating/material and use scenario by series/model; use product data/test reports. Do not mix different series in one table, and separate stock and custom lenses.
Can product images be retouched?
Dust/fingerprint removal, background cleanup and colour/perspective correction are acceptable. Do not change frame shape, colour, material or structure, combine different models, or use AI-generated images as real shots.
Does the export catalogue need English?
It depends on the target market and customer. English/multilingual text needs human review, with consistent model/SKU, material, coating, packaging, certification and units; it is not a page-by-page translation.
Can the catalogue claim “GB/T 14214 compliant”?
Only with a test report/certificate, applicable models and test scope; a standard number is not certification. The current standard is GB/T 14214-2019, and revision plan 20251731-T-607 is in approval; check the official standard page and formal report (National Standards Information Public Service Platform).
How should we choose a catalogue/design vendor in Danyang or elsewhere?
Check the contract entity, eyewear/optical catalogue experience, parameter review, photography, English/export catalogue, printing and delivery, not just a local/non-local label. Lingyi has an office in Changzhou; Danyang work is confirmed on a project basis without claiming a local branch or team.
Bottom line
For a Danyang eyewear/optical product catalogue, align model/SKU, frame dimensions, lens parameters and physical product first, then accept photography, export catalogue and print/digital delivery. Do not estimate parameters from images, change product structure in retouching, or treat a standard number as certification.
