Any honest Free People accessory review must address material realism. The Luna is a lightweight fashion accessory crafted from plated wire alloys, not hand-carved Italian acetate or indestructible titanium. Treating the frame like heavy-duty sports eyewear will result in bent temple arms or misaligned hinges.
The polycarbonate lenses include an exterior scratch resistant coating that deflects light abrasions from dust and fingernails. However, tossing the glasses unprotected into a packed tote bag alongside keys and metal zipper pulls will compromise the finish over time. Routine care determines whether these frames last a single weekend or multiple consecutive summers.
- Rinse before wiping: Always run lukewarm tap water over the lenses to dislodge micro-grit before applying a cloth. Dry-rubbing dusty lenses is the leading cause of micro-swirls on polycarbonate.
- Use dedicated microfiber textiles: Avoid using cotton t-shirt hems, paper towels, or restaurant napkins, which contain abrasive wood pulp fibers.
- Apply neutral lens cleaners: Avoid household glass cleaners containing ammonia or high alcohol concentrations, which can degrade protective optical coatings.
- Store in a semi-rigid pouch: The collapsible soft sleeve provided at retail protects against ambient dust but offers zero crush resistance. Upgrading to a firm sunglasses case preserves the frame alignment.
Tightening the miniature hinge screws once or twice each season with an optical screwdriver also prevents the temple arms from becoming loose or wobbly with repeated wear.
