How Long Does Eyewear Production Take? Lead Times Explained

One of the most common planning mistakes eyewear brand founders make: underestimating how long it takes to get from "I want to make glasses" to "glasses are in my warehouse."

The answer — anywhere from 6 weeks to 6 months — depends on what you're producing, where you are in development, and how quickly decisions get made. This guide breaks down every stage so you can plan your launch timeline realistically.

The Three Phases of Eyewear Production

Lead time in eyewear isn't one number — it's a sequence of phases, each with its own timeline:

1. Development phase: From initial brief to approved pre-production sample

2. Production phase: From production approval to finished goods

3. Logistics phase: From factory to your warehouse

Most people ask about "production lead time" and get an answer of 45–90 days. What they don't account for is the development phase that comes before it — which can double the total timeline.

Phase 1: Development (4–16 Weeks)

Private Label (Stock Shapes):

If you're using frames from a factory's existing catalog:

Sample request to sample in-hand: 2–4 weeks

Sample revision rounds (2–3 expected): 2–4 weeks

Artwork approval (logo, packaging proofs): 1–2 weeks

Total development: 5–10 weeks

Custom OEM (New Molds):

If you're designing something new:

Design brief and concept alignment: 1–2 weeks

3D design and factory concept review: 2–4 weeks

Mold fabrication (tooling): 4–6 weeks

Pre-production sample: 2–3 weeks

Sample review and revision: 2–4 weeks

Total development: 11–19 weeks (3–5 months)

This is where brands fall behind schedule. They plan for the production timeline without accounting for development. If you want frames on shelves in time for a holiday launch, you need to count backwards from that date — not forwards from today.

Phase 2: Production (30–90 Days)

Once samples are approved and you place your production order:

Injection nylon (TR-90): 30–45 days

Metal frames (standard): 45–60 days

Acetate frames: 60–90 days

Titanium frames: 60–90 days

Combination (acetate + metal): 75–90 days

Why does acetate take longer? Acetate production is more labor-intensive. Sheets are cut, shaped, tumbled, polished in multiple stages, and adjusted by hand. Each step takes time that can't be fully automated. Quality acetate from a factory like D.I. Ware simply takes longer than injection nylon — and that's a sign of the process, not a problem.

What can slow production further:

Factory holiday closures (Chinese New Year, Golden Week)

Material lead times if your specified color or material needs procurement

Quality control holds — if first-off-production pieces don't meet spec

Change requests after production starts (avoid at all costs)

Phase 3: Logistics (1–6 Weeks)

From finished goods leaving the factory to arriving at your warehouse:

Sea freight (China to US): 3–5 weeks — Low cost

Air freight (China to US): 5–10 days — High cost

Express courier DHL/FedEx (China to US): 3–7 days — Very high cost

Most brands use sea freight for large orders and air freight when inventory is running low. A common mistake: shipping by sea and assuming 3-week transit when customs clearance, drayage, and delivery add another week or two on each end.

Total Timeline: What to Expect

Private label, existing sample, repeat order: 6–10 weeks

Private label, new colorway, sea freight: 12–18 weeks

Custom OEM, new shape, sea freight: 5–7 months

Custom OEM, new shape + new material, air freight: 4–5 months

Chinese Factory Holidays: Plan Around These

Chinese New Year: Late January to mid-February (factories close 2–4 weeks; order around 6–8 weeks before the holiday)

Qingming Festival: Early April (3 days, but impacts shipping)

Labor Day (May Day): Early May (3–7 days)

Dragon Boat Festival: June (3 days)

National Day / Golden Week: First week of October (7 days; factories often close 1–2 weeks total)

Golden Week in October is particularly important for eyewear buyers — if you're planning a holiday season launch in November or December, your production needs to be complete before Golden Week.

How to Build a Realistic Launch Timeline

Work backwards from your target launch date. Example for a November 15 launch:

November 15 — Launch

November 7 — Inventory received and processed (1 week buffer)

October 15 — Estimated arrival (sea freight: 4 weeks from China + customs)

September 15 — Production complete and goods shipped

July 15 — Production start (acetate, 60-day lead time)

July 1 — Production approval (sample approved, PO placed)

June 1 — Pre-production sample approved (2–4 week revision)

May 1 — First pre-production sample received

March 1 — Development started (custom OEM: 8 weeks to first sample)

That's a March start for a November launch on custom OEM. For private label with an existing sample, the same November launch could start in July.

Tips for Reducing Lead Time

1. Approve quickly: Every day you spend reviewing samples is a day added to your timeline. Designate one decision-maker and stick to fast feedback cycles.

2. Don't change course mid-development: A change to the frame design after tooling is started can mean rebuilding the mold — 4–6 additional weeks and significant cost.

3. Use air freight for the critical first order: Sea freight savings aren't worth a missed launch window. Air the first order; optimize logistics later.

4. Build buffer into everything: Factories give best-case estimates. Plan for 15–20% timeline overrun on first-time styles.

5. Start development on multiple styles in parallel: If you're launching 3 styles, start them simultaneously rather than waiting for style 1 to be approved before starting style 2.

Questions to Ask Your Factory About Lead Times

What's your current production queue? (Tells you if there's backlog)

Are any holidays coming up in the next 60 days?

What's your policy if production runs over the agreed lead time?

Can I pay a rush fee for expedited production?

What triggers the lead time clock — my PO, my deposit, or my sample approval?

Lead time planning is boring — until you miss a launch window because your glasses are sitting in a Shenzhen warehouse during Golden Week. Build in the buffer. Plan backwards from your launch date. And find a factory that gives you honest answers, not optimistic ones.

Ask D.I. Ware about current lead times and availability: https://www.diware.com/contact

D.I. Ware manufactures acetate, metal, titanium, and injection nylon frames in Shenzhen with a standard OEM lead time of 60–90 days from production approval. MOQ: 600 units per style per color.
