Focus on fit, UV protection, and lens quality. Look for UV 400 protection and consider polarization for glare reduction, plus a frame size that matches your face shape.

Key attributes are lens type (plain, polarized, mirrored, or photochromic), lens color, frame material (metal or acetate), and the overall size/fit (lens width and bridge width).

Consider polarization for bright days, tint density, nose pads and hinge durability for comfort, plus frame color that complements your wardrobe and skin tone.

Prioritize polarized lenses or high-contrast tints to reduce glare, a lightweight frame for all-day wear, and a lens color that enhances road visibility.
