Define when you’ll wear them (daily vs. special occasions), then check fit, UV protection, and frame shape that suits your face. Aim for comfortable all-day wear with lenses that block UV.

Lens protection (UV rating and polarization), frame size and shape, and the material for durability and comfort. Color and brand/style can help you get the look you want without sacrificing fit.

Look for polarized lenses for glare reduction, coatings like scratch resistance, nose-pad comfort, and whether you prefer a signature brand (Prada, Tom Ford) for fashion impact.

Ask about polarization for driving, lightweight materials for all-day wear, and frame sizes or shapes that suit your face. Trying a couple of options can reveal what feels and looks best.
