By The Bay/S Sunglasses – Privé Revaux
The Privé Revaux By The Bay/S sunglasses bring coastal California energy to your everyday wardrobe. We designed these oversized cat-eye frames to balance vintage-inspired silhouettes with modern comfort — soft curves meet structured temples for a look that flatters oval, heart, and square face shapes.
Each pair features UV400 lenses that block 100% of UVA and UVB rays, keeping your eyes protected whether you're on a sunrise walk or spending the afternoon at an outdoor café. The acetate construction delivers lightweight durability you'll notice from the first wear, and our signature logo detail at the temple adds the finishing touch. Available in classic black and tortoiseshell colorways, By The Bay/S transitions effortlessly from beach weekends to city errands.
Frame & lens details
Frame Design & Construction
We craft the Privé Revaux By The Bay/S sunglasses using injection-molded acetate, a plant-based material valued for its flexibility and color depth. The oversized cat-eye silhouette measures 145mm across, creating a bold statement without overwhelming your features.
The frame’s upswept outer edges lift and flatter, while the 18mm bridge sits comfortably on most nose shapes. Each temple extends 140mm and tapers gently, distributing weight evenly behind your ears. Our tortoiseshell finish showcases hand-polished detailing that catches light from every angle, and the solid black option delivers timeless versatility that pairs with any outfit.
Lens Protection & Clarity
The lenses in your By The Bay/S sunglasses carry UV400 certification, meaning they filter wavelengths up to 400 nanometers — the full spectrum of ultraviolet light. This comprehensive protection shields your eyes from both short-wave UVB and long-wave UVA rays, reducing exposure that contributes to cataracts and macular degeneration over time.
We use impact-resistant polycarbonate for the lens material, offering durability that withstands everyday knocks and drops. The gray-tinted lenses reduce brightness without distorting color perception, so traffic lights, landscape details, and faces appear true to life. Our standard lenses are non-polarized; if you’re seeking glare reduction for water or driving, explore our polarized sunglasses lineup built on the same frame platforms.
Sizing & Fit Guide
By The Bay/S frames fall into our oversized category, ideal for medium to large face widths. The 55mm lens height provides generous coverage, shielding your eyes and the delicate skin around them from sun exposure. If you typically wear medium frames, these will feel noticeably larger — many of our customers choose oversized styles specifically for that dramatic, fashion-forward effect.
To check fit before ordering, measure your current favorite sunglasses: temple-to-temple width should fall between 140mm and 150mm for the best match. The 18mm bridge works well for average to wider nose bridges; if you have a narrow bridge, consider styles from our women’s sunglasses collection with adjustable nose pads.

We recommend measuring your current sunglasses against our published dimensions to confirm fit before ordering.

Clean acetate frames with lukewarm water and a small drop of mild dish soap. Rub gently with your fingertips, rinse thoroughly, and dry with the included microfiber cloth.
