Square Sunglasses Custom Manufacturing

Square and geometric sunglasses are riding a strong trend wave, with broad unisex appeal that makes them a smart addition to any range. Here is the complete custom manufacturing guide to producing square sunglasses for your brand.

Why square is trending

Bold, angular square frames read modern and confident, suit both men and women, and align with the geometric trend dominating 2026. They balance fashion-forward appeal with broad enough acceptance to sell at volume. See our square sunglasses page and sourcing guides trend report.

Frame construction

The clean-angle challenge

Square frames live on crisp, symmetrical angles. Rounded or uneven corners ruin the look, so edge finishing and symmetry are the critical quality points — especially in acetate where corners are shaped by hand and machine.

Color and finish

• Bold solids and translucents
• Tortoise and havana for a refined look
• Matte finishes for streetwear
• Custom Pantone color injection
• Two-tone and laminated acetate

Lens options

Flat-front square frames suit flat lenses, gradient tints and mirror finishes equally. Mirror lenses pair especially well with the bold geometric look — see lens choices in our sunglasses range.

Custom branding

Square frames have broad temples ideal for branding — metal logo plates, laser engraving or custom temple colors. See our manufacturing capabilities.

Square frames are unforgiving of soft corners. The whole appeal is the clean angle — lose it and you have an awkward not-quite-square frame.

MOQ, pricing and lead time

From our 50-pair MOQ. Injection square frames from ~$2.60/pair at volume, acetate higher; sampling 7–10 days, production 25–35 days. Model it in our free buyer tools.

Why source this from Wenzhou with LumiShades

Wenzhou in Zhejiang Province is widely regarded as China’s eyewear manufacturing capital, producing a large share of the world’s sunglasses. That concentration matters to buyers: a deep local supply chain for acetate sheet, hinges, lens blanks, plating and packaging means shorter component lead times, easier color and material matching, and a workforce with decades of eyewear-specific skill. LumiShades has manufactured in this ecosystem since 2009, and our vertical integration — in-house injection molding, acetate cutting, CNC milling, lens tinting, decoration and quality control — means no part of custom square sunglasses is quietly subcontracted to a workshop you cannot audit.

For international buyers, that vertical control translates into accountability. When a single factory owns every step, defects are traced and fixed at source rather than bounced between vendors, and your specifications survive intact from first sample to bulk. We back this with 15+ years of experience, shipments to 60+ countries, more than 5 million pairs produced per year and a 98.5% on-time delivery rate. Our certifications — CE EN ISO 12312-1, FDA registration, ANSI Z80.3, AS/NZS 1067, REACH, ISO 9001 and BSCI audit — mean the compliance documentation your market requires already exists. Explore our manufacturing capabilities and quality control process to see how this works in practice.

Frequently asked questions

What is the minimum order quantity? Our MOQ is 50 pairs per design, which lets new brands and buyers validate custom square sunglasses before committing to volume. Pricing improves at 300, 1,000 and 5,000+ pairs, dropping as low as $2.10 per pair on volume programs.

How long does it take? Samples are ready in 7–10 days and bulk production runs 25–35 days, plus QC, packing and shipping. Using an existing frame shape avoids new tooling and is the fastest route; fully custom moulds and acetate builds add time.

Can you handle custom branding and compliance documentation? Yes. We decorate in-house (laser engraving, pad printing, metal logo plates, custom temple colors and packaging) and provide the UV, impact and standard-specific test reports your destination markets require. Tell us your target countries up front and we build the right documentation into the order.
