Start with fit and comfort—check the lens width and bridge size to avoid pinching. For style, consider whether you want a bold clear frame or a subtle, near-invisible look that complements your skin tone.

Key factors are UV protection (look for 100% UV or UV400), lens type (polarized vs non-polarized), frame material, and overall fit (temples, bridge, weight).

If you’re outdoors often, polarization helps with glare. For all-day wear, lightweight frames and comfortable nose pads aid comfort. Also consider lens color and scratch resistance for everyday use.

For everyday wear, choose lightweight, UV-protective frames with a clear style and moderate lens tint; for driving, polarized lenses reduce glare; for social occasions, pick a frame shape that flatters your features.
