Look for 100% UV protection (UV400), a comfortable fit for your face, and a lens tint you like; a wrap-style frame can offer extra coverage if you want a more secure feel.

Key attributes include UV protection, lens type (polarized vs non-polarized), lens tint and coating, frame size/material, and wrap coverage for better sun protection.

Polarized lenses reduce glare from roads and water; for driving, amber/brown tints can boost contrast, while gray tints preserve natural colors; choose based on typical use.

For driving, choose glare-reducing lenses with stable tint; for beach days, look for high UV protection and full coverage; for outdoor workouts, pick lightweight, secure-fitting frames with good grip.
