The Delio isn’t a mere tool to block the sun – when worn, it becomes part of who you are. Crafted from Italian acetate, Delio’s iconic square frame isn’t just for show; it’s a nod to the ageless rebels, the outliers, the ones who live on their own terms. With optically superior mineral glass lenses, Delio delivers a visual clarity that is as sharp as your instincts.

Absorbs 84% to 90% of the visible light in Trivex Polarized lens.

Meet Onyx. Forged in fire — literally. Hydrogen-fired, heat-tempered, and finished with a flash mirror, Onyx is Serengeti’s refined take on a gray lens built for brutal light. Designed to perform where glare is relentless, its photochromic category 3–3 darkens as conditions intensify, while a carefully tuned gray base preserves natural color balance and enhances contrast with precision. Color stays true, details stay sharp — a gray lens worthy of the Serengeti name.

ULTRA MINERAL LENS

EXPERIENCE THE ULTIMATE LENS ON THE MARKET

Our mineral lenses are made with borosilicate optical glass, from Corning®.
A full 20% thinner and lighter, our Borosilicate mineral glass lenses are finer than any other lens. Produced in the same process normally reserved for ophthalmic-quality corrective lenses, they provide the best visual acuity you could ever experience.

Every pair of Serengeti® mineral lenses is unique: each Photochromic lens passes through a Hydrogen-fueled Lehr furnace, which activates the Spectral Control® technology - with varying temperatures that determine the proprietary lens hue.

They are also chemically tempered to ensure scratch and impact resistance.

To complete this unrivalled visual experience, an anti-reflective coating is added to the backside of the lens, canceling the scattering light that causes reflective glare.
