Focus on UV protection (UV400 or higher), lens type (polarized can reduce glare), wrap coverage for better eye protection, and a comfortable fit (bridge width, temple length) suitable for unisex sizing.

Key attributes are lens quality and tint, UV protection level, polarization, frame durability/material, and how well the wrap design fits your face for consistent coverage.

Consider your typical activities (driving, outdoor sport, daily wear), desired lens tint, coatings (anti-scratch or anti-reflective), and comfort features like lighter weight or rubberized grips.

Prioritize all-day comfort, strong UV protection, glare reduction if you’re outdoors, and a versatile color/finish that pairs with most outfits.
