Focus on UV protection (UV400 or 100% UV), lens type (polarized can reduce glare), and a frame that fits your face and provides comfortable coverage.

Lens performance (UV protection and polarization), frame fit (size/bridge/temple length), and frame material/durability along with price or warranty.

Think about how you’ll use them (daily wear, driving, sports), venting or weight, lens tint/color, and whether you prefer metal or plastic frames.

Prioritize glare reduction with polarized lenses, good wrap coverage for wind protection, and a lightweight, secure frame for comfort during extended wear.
