Serengeti Piers Progressive Sunglasses are a lightweight pair of fashion sunglasses, part of the Flex series of prescription sunglasses by Serengeti. These Serengeti prescription sunglasses are equipped with exclusive Polar PhD lenses, utilizing innovative polarized and photochromic lens technologies. You will be impressed every time you put on your prescription sunglasses, thanks to the Spectral Control technology, which provides unparalleled contrast and superior color enhancement by filtering out specific colors for crisper color and clearer images. Since they're part of the Serengeti Flex series, Serengeti Piers Prescription Sun Glasses feature flexible, ergonomic temples for improved comfort and fit. The PhD lenses on these Serengeti sunglasses are finished with anti-scratch, anti-reflective and oleo phobic coatings for oil and water resistance. Visual performance is simply unsurpassable when you wear Serengeti, as proven by the Serengeti Piers Rx Progressive Shades.
