Focus on UV protection, polarization, and fit. Look for a sturdy metal frame in gunmetal, comfortable nose pads, and lenses with UVA/UVB protection; polarized lenses help reduce glare in bright conditions.

Key attributes to compare are polarization, UV protection level, lens tint or color, frame size/fit, and the finish of the metal frame. These factors affect visibility, comfort, and how the style looks on you.

Think about when you’ll wear them (daily, driving, outdoor activity) and your face shape. If glare is a concern or you drive a lot, polarized lenses and a comfortable fit become more important.

Compare polarization options, lens size, and bridge design. The RB3025 is the classic teardrop aviator, while RB3689 variants offer different proportions—choose based on which fits your face and whether you prefer polarized lenses for glare control.
