Metal Square Sunglasses

The rise of metal square sunglasses isn’t just a trend—it’s a calculated response to consumer demands for durable, high-performance eyewear that balances urban aesthetics with outdoor functionality. As a specialized manufacturer in metal-PC hybrid frames and polarized lenses, we’ve engineered every component to empower your brand’s growth. Here’s what sets our products apart—and why bulk buyers keep returning.

1. Frame Construction: Where Metallurgy Meets Polymer Science

Our metal square sunglasses have stainless steel for the frame—a material chosen for its hypoallergenic properties and resistance to saltwater corrosion (critical for coastal retailers). Encasing this core is reinforced polycarbonate (PC) molded at 280°C, creating a lightweight shell that absorbs impact forces up to 130J (tested via ANSI Z80.3-2015 standards). This fusion achieves a 55-58g total weight—22% lighter than full-metal competitors—while maintaining the rigidity needed for sports and daily wear.

We proudly introduce our latest batch of Metal Square Sunglasses, designed to help you capture the pulse of modern fashion. With their classic square silhouette and lightweight, durable metal frames, these sunglasses perfectly blend vintage charm with modern minimalism. They are an essential, high-demand product for any retailer seeking quality, style, and high turnover.

Choosing high-quality eyewear is not just a style statement—it’s a calculated business move. The immense potential of the optical market is clearly reflected in industry data. According to The Vision Council, the U.S. optical industry was valued at over $65 billion in 2023, underscoring the sustained, strong consumer demand for high-quality vision protection and fashionable accessories.

2. PC Lenses: Optical Precision for Niche Markets

Unlike cheap PET lenses that distort colors, our 5-axis CNC-milled PC lenses maintain <0.1% wavefront distortion, crucial for applications like fishing or driving where visual accuracy matters. PC lens isn’t a simple film—it’s chemically bonded during injection molding, ensuring:

UV400 protection (blocks 100% of UVA/UVB/UVC)

Hydrophobic coating that repels water/oil (contact angle: 115°)

Need to tailor lenses to specific environments? We provide:

VLT (Visible Light Transmission) customization: 8% for glacier expeditions, 18% for cycling, 80% for night driving

Mirror coatings: Dual-layer deposition for iridescent effects (rose gold, blue shift) popular in fashion markets

Laser-etched branding: Micro logos at the lens edge (min. 0.8mm height)
