Prioritize fit and lens protection: pick sunglasses with 100% UV protection, a frame size that fits your face proportions, and comfortable nose pads/temples. Round frames should sit securely without sliding.

Lens type and tint, UV protection, polarization (if you want glare reduction), frame material and size, and how the style matches your face shape and personal preference.

Polarized lenses reduce glare on bright days and reflective surfaces. If you need vision correction, check whether the style supports Rx lenses or is available in prescription-friendly options.

Choose a durable frame (metal or acetate) with a comfortable fit and a medium bridge. Opt for a neutral lens tint and standard sizing to suit most face shapes.
