Consider your face size and shape, the fit of the frame, and how much sun protection you want. Look for 100% UV protection and a frame that sits comfortably across the temples and bridge.

Key factors are frame size and shape, lens type (polarized versus non-polarized), UV protection, lens tint, and frame material for durability. Choose polarization if glare is a concern.

For driving, polarized lenses and neutral tints help reduce glare. For sports, look for wrap‑style frames and impact‑resistant lenses. For everyday wear, lightweight frames and versatile colors suit most outfits.

Choose smaller or narrow frames with a comfortable bridge and temple width to avoid slipping. Rectangular or angular shapes often balance a smaller face well.
