Featuring a structured square frame, these unisex sunglasses offer the perfect blend of fashion and function, providing high-quality polarized vision.

The RB3721CH features adjustable nosepads which allow for a more customizable fit, making them versatile for many face shapes, though they have a bold square profile.
Yes, many Ray-Ban metal frames are compatible with prescription lenses. It is recommended to visit an authorized optical retailer to verify compatibility.
Polarized lenses can sometimes make LCD screens look dark or distorted depending on the screen's angle, which is normal for this technology.
Yes, the RB3721CH design is gender-neutral and designed to complement a wide range of face types and personal styles.
Use a hard-shell protective case to prevent the metal frame from bending and to protect the lenses from impact or compression.
Adjust the metal nosepads inward slightly and ensure the temple arms are resting securely behind your ears.
Use a dedicated microfiber lens cloth to gently buff away oils. For persistent residue, use water and a tiny drop of dish soap, then rinse and dry thoroughly.
Ensure the lenses are clean and free of debris. If the polarization seems ineffective, check if you are looking through a screen that has its own polarized layer, which may cause visual artifacts.
To achieve the best fit, adjust the nosepads gently by pressing them closer together or wider apart until the frame sits comfortably on the bridge of your nose. When not in use, always store the sunglasses in a protective hard case to shield the metal frames from impacts and the lenses from surface scratches. To clean, use a microfiber cloth and a mild, alcohol-free lens solution. Avoid using paper towels or abrasive fabrics, as these can leave micro-scratches on the lens coating. If the frame feels loose over time, take them to a professional optician for a frame alignment.
