Craftsmanship & Structural Highlights

• Vacuum IP (Ion Plating) Surface Finish
  Utilizes advanced physical vapor deposition (PVD) ion plating in a vacuum chamber. The matte black coating bonds at a molecular level with the titanium base, delivering superior hardness, scratch resistance, and sweat-corrosion endurance compared to traditional electroplating.
• Precision Multi-Axis Titanium Folding Architecture
  Engineered with high-tolerance micro-hinges at the double bridge and temple midpoints, allowing the frame to flatten and collapse into a pocket-sized form without sacrificing structural integrity.
• Featherlight Pure Titanium Core
  Machined from high-grade titanium to drastically reduce frame weight, relieving pressure on the nasal bridge and ears while remaining 100% skin-friendly and nickel-free.
• Advanced HD TAC Polarized Optics
  Fitted with high-contrast TAC polarized dark smoke lenses that effectively filter scattered glare from asphalt, glass, and water surfaces while offering complete UV400 protection.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of IP (Ion Plating) black over standard black spray painting or traditional electroplating?
A1: IP plating is performed in a vacuum environment where metal ions bond deeply with the titanium substrate. It creates a much harder, wear-resistant surface that will not peel, chip, or corrode when exposed to human sweat or UV rays.

Q2: Will the folding hinges loosen after repeated daily folding and unfolding?
A2: No. Our folding bridge and temple hinges use precision micro-screws paired with wear-resistant nylon washers, maintaining consistent friction tension and smooth folding action over years of use.

Q3: Can optical labs fit prescription sunglass lenses into this folding titanium frame?
A3: Yes. The titanium rim lock screws are engineered for easy lens mounting, allowing opticians to glaze single-vision or progressive prescription polarized lenses into the frame.
