FAQs
What does 'Bio-Based' mean for these sunglasses?
'Bio-Based' indicates that the frame is made from materials derived from renewable resources, contributing to a more sustainable product.
Are the lenses polarized?
No, the description states 'Brown solid-color lenses,' which typically refers to standard tinted lenses, not polarized ones.
What is the `51-20` size designation?
This refers to the lens width (51mm) and the bridge width (20mm), which are standard measurements for sunglasses sizing.
Can I replace the lenses with prescription lenses?
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.
How should I clean the frame?
Clean the frame with a slightly damp cloth. Avoid harsh chemicals or prolonged exposure to heat.
What is the main color of the frame?
The frame has a Violet Havana color family, described as vibrant violet.
Are these sunglasses suitable for intense sunlight?
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.
Troubleshooting
Sunglasses feel too tight or loose
Minor adjustments can sometimes be made by a professional optician. However, ensure you have selected the correct size for your face.
Lenses are smudged or dirty
Use a dedicated lens cleaning solution or a slightly damp microfiber cloth. Avoid touching the lenses directly with your fingers.
Frame material seems warped
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.

Setup, Compatibility & Care
Setup:
These sunglasses require no setup. They are ready to wear straight out of the box.
Compatibility:
As eyewear, their primary compatibility relates to fit. The `51-20` sizing indicates a lens width of 51mm and a bridge width of 20mm, designed for a standard adult fit. They are compatible with most face shapes, though the slim oval style is particularly suited for those with more angular features or those who prefer a less dominant frame.
Care:
- Cleaning Lenses: Gently wipe lenses with a soft, lint-free microfiber cloth. Avoid using abrasive materials or household cleaners, which can damage lens coatings.
- Frame Care: Clean the bio-based frame with a slightly damp cloth. Avoid exposing the sunglasses to prolonged heat (e.g., leaving them on a car dashboard) as this can warp the material.
- Storage: Store your sunglasses in the provided case when not in use to protect them from scratches and damage.
