Serengeti Molecular Technologies
Some of the most fascinating technology in the car isn't a part of the car at all. For example, every pair of Serengeti sunglasses is equipped with photochromic technology, which helps the sunglass lenses change as quickly as the scenery. With photochromic lenses, the molecules inside the lenses adjust to the changing light conditions, causing them to lighten and darken automatically. The keeps your eyes from straining or growing tired, as the lenses do most of the work for you. Plus, the photochromic technology is inherent in the glass, so it never wears off or wears out. The lenses also offer Spectral Control technology, which provides unparalleled hi-def contrast and superior color enhancement by filtering specific colors from the visible light spectrum. This, in turn, results in crisper color and clearer images. In addition, Spectral Control lenses block the distracting blue light that causes blurring, minimizing eyestrain and eye fatigue. Finally, many of Serengeti's glasses include polarized lenses with glare reduction technology. Light tends to bounce and reflect off a myriad of surfaces, such as water, snow, or the road. Serengeti polarizing technology, however, removes the glare--and the stress it causes on your eyes. Serengeti's eye protection goes well beyond government and commercial standards, helping your eyes stay sharp and stay safe.
