Bold Double Layer Step-Cut Solid Acetate TAC Polarized Sunglasses | OEM & ODM Manufacturer
The ME2078 is designed for brands that want more than a standard square sunglass. Instead of using laminated layers or glued components, this model is sculpted from a single block of premium solid acetate using advanced one-piece double-layer CNC step-cut technology. The result is a distinctive architectural profile with genuine depth, clean geometric lines, and exceptional structural integrity.
The bold square silhouette creates a strong fashion presence while remaining comfortable enough for everyday wear. Paired with UV400 TAC polarized lenses, it delivers reliable glare reduction and clear vision, making it suitable for both lifestyle fashion and outdoor activities.
Available in four timeless acetate colors, this model is an excellent choice for eyewear brands, fashion retailers, boutique stores, and private label collections looking for differentiated products that stand out in today's competitive market.
Product Features
✔ Exclusive One-Piece Double-Layer CNC Construction
Unlike conventional double-layer frames that are bonded together with adhesives, the ME2078 is precision milled from a single thick acetate block. This integrated construction creates authentic stepped contours while eliminating the risk of delamination over time.
✔ Premium Thick Solid Acetate
Manufactured from high-quality solid acetate for enhanced durability, excellent color stability, and a premium hand-polished finish that maintains its appearance through daily use.
✔ TAC Polarized UV400 Lenses
High-performance TAC polarized lenses effectively reduce glare from roads, water, snow, and reflective surfaces while providing full UV400 protection against harmful UVA and UVB rays.
✔ Comfortable Integrated Saddle Bridge
The one-piece saddle bridge distributes weight evenly across the nose, providing a secure fit without the need for adjustable nose pads.
✔ Reinforced Metal Hinges
Durable metal screw hinges are individually tension-adjusted to ensure smooth opening and closing while maintaining long-term reliability.

Craftsmanship
Every ME2078 frame is produced through a carefully controlled manufacturing process to ensure consistent quality and long-term durability.
Production begins with premium solid acetate sheets that are stabilized under controlled temperatures to minimize internal stress before machining.
Using advanced CNC technology, each frame is carved from a single acetate block through a multi-level step-cut process. Unlike laminated double-layer frames, this method creates the distinctive layered appearance without adhesives or separate components, resulting in a stronger and more refined structure.
After machining, every edge and contour is hand-polished through multiple finishing stages to achieve a smooth, high-gloss surface while preserving the frame's bold geometric definition.
Each hinge is manually assembled and adjusted to provide consistent opening tension. Finally, every finished pair undergoes inspections for hinge durability, lens alignment, surface finish, and overall assembly before packaging.
