Look for a comfortable fit (frame size and bridge width), UV protection (UV400), and lens quality with a neutral grey tint for versatile glare reduction. Polarized lenses help in bright conditions, though they aren’t essential for every shopper.

Key factors are UV protection, lens type (polarized vs non-polarized), frame material and durability, and size/fit (bridge width, temple length).

For driving or outdoor use, consider polarized lenses and a secure fit; for daily fashion, prioritize brand/style, acetate vs metal frames, and color finish.

Filter by brand and check frame material and sizing options to ensure the look suits your face; consider polarized lenses for glare control if you'll be outdoors a lot.
