KOJI Frames Category Overview
KOJI Frames is a curated collection of ergonomic eyewear designed for comfort-first fit and modern styling.

Refined geometry, stable bridges, and balanced weight deliver dependable daily wear and a consistent identity.
Key Benefits
Ergonomic Fit and Stability
Fit drives every design. Optimized bridge widths, adjustable nose pads, and tuned temple curves reduce slipping and pressure points for Asian-fit needs while maintaining lens stability.
Materials and Craftsmanship
Choose titanium for ultralight strength, semi-titanium for balanced value, and TR or Ultem for resilient flexibility. Acetate fronts provide dimensional color and tactile comfort. Precision milling, IP/PVD plating, and careful polishing support longevity.
Design Language
Options include double-bridge silhouettes, round and Korean circle shapes, sleek rectangles for professional wear, and keyhole bridges with vintage cues. Thin-gauge metal rims and sculpted acetate fronts create recognizable yet lightweight profiles.
Reliability and Support
Certified processes, multi-stage QC, and traceable materials promote consistent quality. Robust hinges, plating adhesion, and colorfast acetate are validated for long-term use. Warranty terms can be tailored to program needs.
Customization and OEM/ODM
Branding and Visual Identity
Apply laser or embossed marks, customize temple cores, and align hardware to brand codes. Acetate lamination, gradient tints, and plated accents enable cohesive storytelling for private-label programs.
Materials, Finishes, and Colors
Specify pure or semi-titanium with brushed or matte IP/PVD finishes; acetate in tortoise, navy, or crystal; or TR/Ultem for flexibility. Anti-fingerprint and hypoallergenic coatings are available.
Lens and Function Options
Configure optical or sun builds with polarized, photochromic, or mirror lenses. Optical-ready designs support demo lenses, adjustable pad arms, and bevels compatible with high-index prescriptions.
