Ray-Ban Sunglasses Khal Bio-based - Violet Havana Frame Brown Lenses 51-20

'Bio-Based' indicates that the frame is made from materials derived from renewable resources, contributing to a more sustainable product.

No, the description states 'Brown solid-color lenses,' which typically refers to standard tinted lenses, not polarized ones.

This refers to the lens width (51mm) and the bridge width (20mm), which are standard measurements for sunglasses sizing.

While some Ray-Ban frames can accommodate prescription lenses, it's best to consult with an authorized optician to confirm compatibility for this specific model.

Clean the frame with a slightly damp cloth. Avoid harsh chemicals or prolonged exposure to heat.

The frame has a Violet Havana color family, described as vibrant violet.

The brown solid lenses provide protection and glare reduction, making them suitable for general sunny conditions. For very intense or specific activities like driving or snow sports, polarized or specialized lenses might be preferred.

Minor adjustments can sometimes be made by a professional optician. However, ensure you have selected the correct size for your face.

Use a dedicated lens cleaning solution or a slightly damp microfiber cloth. Avoid touching the lenses directly with your fingers.

Do not attempt to bend the frame back yourself. Exposure to excessive heat is the likely cause. Consult an optician or the retailer for potential solutions.
