The Frame
Dark Havana acetate. Hand-finished in a deep, layered tortoiseshell brown that shifts depending on the light — never flat, never generic. Acetate is cut and polished rather than injection-moulded, which means every pair carries small, natural variations in the grain. No two are identical.
Keyhole bridge. A structural, vintage-inspired bridge shape that sits closer to the face for a more secure, all-day fit — it also happens to be one of the most flattering bridge cuts across face shapes.
The Lenses — G15 Green, Photochromic + Blue Light
Photochromic technology. The lenses actively respond to UV light. Step outside and they darken within seconds; step back indoors and they lighten back up. One pair, no swapping — full coverage across shifting light without needing a second pair of sunglasses for driving, walking, or moving between indoor and outdoor spaces.
Blue light filtering. Built into the same lens, this layer reduces high-energy visible light from screens — a quiet nod to the fact that most of us are staring at a phone or laptop more than we're outside. The Serval is engineered to work in both worlds without asking you to choose.
How it works together: one lens, three jobs — UV protection and glare reduction outdoors via the G15 tint, automatic light adaptation via the photochromic layer, and screen comfort indoors via blue light filtering. You put them on once and they adjust to you.

Care
Store in the provided case when not in use. Clean with a microfiber cloth — avoid paper towels or clothing, which can scratch the acetate finish over time. Avoid leaving the frame in extreme heat (e.g. a hot car), as acetate can warp.
Each pair is preordered and made to order in small batches — not stocked, not mass-produced. What you're wearing was made because you asked for it.
