Ray-Ban sunglasses BO-034

Key Features Observed:
Lenses: The "Ray-Ban" script on the upper corner of the right lens and the gold sticker on the left lens suggest these are the classic G-15 mineral glass lenses, known for high clarity and "natural" color transmission.
Frame Style: The thick temples and distinct silver rivets on the end pieces are hallmarks of the Wayfarer silhouette.
Markings: The inner temples contain the manufacturing information (e.g., "MADE IN ITALY") and the model/sizing code (e.g., RB2140 or RB2132).
Understanding the Sizing
If you are looking to find the exact size or model of this pair, you can find a series of numbers printed on the inside of the left temple. They usually look like this: 50 □ 22 150.
Lens Width (e.g., 50): The horizontal width of one lens.
Bridge Width (e.g., 22): The distance between the two lenses.
Temple Length (e.g., 150): The length of the "arm" from the hinge to the tip.
Quick Authenticity Check
Ray-Bans are frequently counterfeited. To check if your pair is genuine, look for these subtle details:
The RB Etching: Look very closely at the far edge of the left lens (the one without the white logo). There should be a tiny "RB" laser-etched into the glass.
Hinge Quality: Authentic Wayfarers usually have high-quality metal hinges (often 7-barrel hinges) that feel sturdy and smooth, not flimsy plastic.
Weight: Because they use glass lenses and high-quality acetate, they should feel "hefty" rather than light and "plasticky."
