Frequently Asked Questions (FAQ)

Q1: What are the primary advantages of Category 2 (Cat.2) polarized lenses compared to Category 3?
A1: Category 2 lenses allow slightly more light transmission (18%-43% VLT), making them versatile for mixed lighting conditions like overcast days, shaded roads, late afternoons, and transition from outdoors to cars, where dark Cat.3 lenses might feel overly dim.

Q2: Is the metal frame nickel-free and hypoallergenic for users with sensitive skin?
A2: Yes. All metal plating processes utilize hypoallergenic, nickel-safe coatings, paired with skin-friendly silicone nose pads and smooth temple tips to prevent skin irritation.

Q3: Can these frames be fitted with prescription TAC or CR39 lenses?
A3: Absolutely. The sturdy full-rim metal wire is designed with a standard optical bevel groove, allowing easy lens mounting for custom prescription sunglass lenses (Rx-able).
