Frequently Asked Questions (FAQ)

Q1: Will the filigree engraving on the bridge and temples fade or wear off over time?
A1: No. The engraving is deeply etched into the titanium substrate via high-precision laser work before plating, ensuring the intricate pattern remains crisp and clear throughout the life of the frame.

Q2: Is acetate rim combination eyewear heavier than full titanium frames?
A2: While the acetate rim adds slight visual substance, utilizing ultra-thin beta-titanium for the temples, bridge, and chassis keeps the overall weight under 25 grams, maintaining excellent featherlight comfort.

Q3: Can these combination frames be retrofitted with prescription sunglass lenses?
A3: Yes. Optical labs can easily remove the stock polarized lenses and mount single-vision or progressive prescription lenses into the acetate rim lock structure.
