Lens Materials, Features, Frames

POLYCARBONATE LENSES - Very impact resistant and light weight.  Perfect for active lifestyle, sports, and safety glasses.  More impact resistant than glass or plastic lenses and provides protection from harmful UV rays.

POLAR PHD LENSES - Made with Trivex material that is 75% lighter than glass and 10% lighter than polycarbonate.  Reduces lens weight, improves strength, Serengeti Polar PhD lenses deliver exclusive hues and high-definition benefits that are near-glass in clarity.  In fact, it’s as optically close as you can get to a glass lens.  Polar PhD features the utmost UVA/UVB protection, photochromic, Spectral Control and polarization technology.

ULTRA-LIGHT GLASS - A full 20% thinner and lighter than standard glass lenses, Serengeti’s ultra-light glass is the most optically superior lens on the market.  Serengeti glass lenses begin with borosilicate optical glass from Corning and are chemically tempered to ensure scratch and impact resistance.

PHOTOCHROMIC LENSES - Darkening in bright sunlight and lightening in overcast conditions, photochromic lenses provides your eyes with the optimal amount of light at all times so you can adapt to any light, anytime, anywhere.  The lens transmittances amounts vary depending on UV light conditions: Darkened lens 9%, Lightened lens 24%. Light transmittance amounts vary based on lens color and material.  See Serengeti Lens Technology for more details.

HYDRO AND OLEPHOBIC COATINGS - Repels water, fingerprints, and debris while and anti-reflective coating absorbs glare to eliminate backside reflections.

ANTI-REFLECTIVES COATINGS - Absorbs glare to eliminate backside reflections.

Frame Materials


A lightweight material that's loaded with technology, taking the Genus collection where no sunglass has gone before.



Using only the highest quality injected nylon for superior durability, these fashionable frames have the added benefit of being exceptionally light, chemically resistant, extremely flexible and comfortable.



All natural and produced from cotton, Cellulose Acetate is not only lightweight, but it can be made into beautiful patterns and brilliant hues. Pliable when heated, it is ideal for custom fitting.



Lightweight, extremely strong and corrosion resistant, titanium is used in everything from sports equipment to space capsules. Beta titanium, a combination of vanadium and alumnium, is lightweight, strong and highly flexible, ideal for use in temples, as it expands the fit range of the sunglass. Memory titanium is a combination alloy that is flexible and lightweight, with the ability to return to its original shape when bent or twisted.


Titanium frames are 25% lighter than traditional alloys with unmatched durability. The technical benefits of titianium and the right, sophisticated aestetic of acetate make for a frame collection that is truly distinguished.



Made from corrosion-resistant and hypoallergenic titanium alloy, the frames are 25% lighter than standard alloy. So you're assured of not only a durable pair of glasses, but also a comfortable, secure and customized fit.
