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.
