Prioritize fit, lens quality, and protection. Look for UV protection (UV400 or higher), polarized options if glare is a concern, and a frame size that fits your face comfortably.

Key criteria are lens type (polarized vs non-polarized), UV protection, frame material, and overall size/fit. Also consider bridge style and nose pads for all-day comfort.

Polarization for glare reduction, tint shade for typical lighting, and frame durability or weight help comfort and performance.

For commuting choose a mid-size round frame with solid UV protection; for outdoor activities pick polarized lenses and a lightweight, durable frame; for a versatile daily look choose a neutral finish that goes with most outfits.
