A sample is the moment your eyewear becomes real — the first time you hold your design instead of imagining it. Getting sampling right is what separates a smooth production run from an expensive disappointment. Here’s exactly how the process works.
Key takeaways
- Sampling turns your design into a physical prototype you approve before mass production.
- Standard samples: 7–14 days, USD 30–80/style, usually refundable on a bulk order.
- Expect at least one revision round — build it into your timeline.
- Approve and keep a golden sample as the production and QC reference.
- Precise, written feedback (measurements + photos) gets your frames right faster.
What is eyewear sampling?
Sampling is the prototyping stage of eyewear manufacturing. Before committing to a 500-piece production run, the factory makes one or a few physical samples so you can check the design, fit, materials, color, weight and finish in your hands — and request changes while they’re still cheap to make.
It applies to both OEM (your design) and ODM (you customize the factory’s design). For how those models differ, see OEM vs ODM vs private label.
The eyewear sampling process step by step
- Design / tech pack. You share a sketch, CAD file, reference sample or full tech pack with measurements, materials and colors.
- Quotation & feasibility. The factory confirms it’s producible, proposes materials and construction, and quotes the sample fee and unit price.
- Sample making. The prototype is hand-crafted — cutting, assembly, lens fitting, finishing — over about 7–14 days.
- Your review. You inspect fit, finish, color, weight and function against your intent.
- Feedback & revision. You send precise changes; the factory makes a revised sample.
- Golden sample approval. Once correct, you approve a final golden sample that both sides keep as the master reference.
- Into production. Bulk production runs against the golden sample with multi-stage QC.
How long does sampling take, and what does it cost?
| Item | Typical |
|---|---|
| Standard sample time | 7–14 days |
| Complex/tooling sample | up to 21 days |
| Sample fee | USD 30–80 / style |
| Refundable? | Usually credited against a bulk order |
| Revision round | Adds a short additional cycle |
Sample fees feel high per unit because a one-off prototype takes far more labor than a mass-produced piece. The fee is normal — and usually refunded once you order in bulk.
Types of eyewear samples
- Counter / reference sample — an existing style sent so you can judge quality and finish.
- Custom sample (no tooling) — your design built from existing molds and materials.
- Custom sample (with tooling) — requires new molds; higher cost and longer time.
- Pre-production sample — the final golden sample that confirms mass-production quality.
How to give good sample feedback
Vague feedback causes extra revision rounds. Precise feedback gets it right fast:
- Be specific and measurable — “shorten temples by 3mm,” not “make it smaller.”
- Use photos with annotations and a reference object for scale.
- Reference the golden standard — Pantone codes for color, exact dimensions.
- Separate must-fix from nice-to-have so priorities are clear.
- Confirm in writing before the revised sample is made.
From approved sample to production
Once you approve the golden sample, it becomes the reference every production unit is checked against. Plan a few buffer days for a possible revision round, and pair production with a pre-shipment inspection. For the full launch journey, see how to start an eyewear brand.
