Hydrogen-fueled lehr furnaces activate each lens with our photochromic and spectral control technologies, with varying high temperatures determining the proprietary lens color.
A full 20% thinner and lighter, our ultra-light glass lens is the most optically superior lens on the market. Serengeti glass lenses are made from only the finest materials—providing unsurpassed visual acuity.
ULTRA-LIGHT GLASS LENS
POLAR PHD™ lens
Our glass lenses begin with borosilicate optical glass from Corning,® which can withstand extreme temperature changes. The lenses are chemically tempered to ensure scratch and impact resistance, then ground to perfection.
The lenses then undergo Serengeti’s ® Hydrogen Firing Process, which activates the photochromic and Spectral Control® technologies. After the lenses cool, they are treated with a unique coating that protects their edges, all while being monitored by a technician who examines every lens by hand to ensure the highest quality.
Staying true to Serengeti’s commitment to craftsmanship, we give unparalleled attention to detail throughout every phase of the lens-making process.
