Aim for true polarization to cut glare and UV protection (UV400+). Choose a square frame that fits your face well with a comfortable bridge and temples, and pick a lens tint suited to your typical lighting.

Polarization quality, UV protection, frame material, and fit (face size and bridge) are the core factors; price is also worth considering. Look for coatings like scratch resistance and a tint that suits your daily activities.

Driving benefits from strong glare reduction and a balanced tint; outdoor use may require a tint that enhances contrast and a secure fit for movement. Weight and grip comfort also matter for long wear.

Start with fit and comfort (frame width and temple length), then consider style and color that match your wardrobe. Brand silhouettes often influence how the lenses align and how the glasses rest on your face.
