Some Ray-Ban models allow for prescription lens replacement, but this is not explicitly stated for the Flacko model. It is recommended to consult with an optical professional or authorized Ray-Ban dealer.

The bio-based nylon frame can be cleaned with a soft, slightly damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the frame's finish.

Red lenses can enhance contrast in certain conditions, but they may alter color perception, which is important for driving safety (e.g., traffic lights). It is advisable to check local regulations and consider using them in specific lighting conditions or for recreational purposes.

Due to the unisex design, fit can vary. If the sunglasses feel too loose, a slight adjustment by a professional optician may be possible, or consider purchasing additional nose pads if available. If too tight, they may not be the ideal fit for your face shape.

This can be a characteristic of colored lenses. The Red lenses are designed to provide a specific aesthetic and contrast enhancement. If the distortion is significant, it could indicate a manufacturing defect, and you should contact customer support.

While bio-based nylon is durable, it can become brittle if exposed to extreme temperatures for prolonged periods. Store them properly and avoid leaving them in hot cars. If brittleness is observed under normal conditions, contact customer support.
