Start with a frame shape that flatters your face and a size that fits comfortably. Then check the lenses for UV protection (UV400) and consider whether you want polarization for glare reduction.

Lens quality and protection (UV rating, polarization if available), frame material and weight, and the fit (bridge width and temple length) to ensure wearing comfort all day.

Look at the shape options (round metal, octagonal, hexagonal) for the retro vibe you prefer and how the gold-tone finish complements your wardrobe and skin tone.

If you want vintage flair, opt for classic shapes like round metal or octagonal frames in a gold finish, and choose lenses with UV400 protection; for driving or bright light, consider polarized lenses for glare reduction.
