Serengeti Flex Tosca Polarized Sunglasses for Women & Men - UV Protection, Lightweight & Comfortable - Perfect for Driving, Travel & Outdoor Activities

Serengeti are quality sunglasses. I chose the driver model with photo chromic. They are easy on eyes with good clarity. My package arrived earlier than expected with some damage to the box but the hard case protected the glasses. Price was better than most sites. I now have worn the glasses a majority of my days since Nov. 2013. During that time the right lenses kept falling out, tightened by optometry company but the screw kept coming loose. Lens fell for the 3rd time and sent back to Bushnell under warranty (2 year). Denied warranty claim due to their conclusion it was a bent frame. Lens was scratched when it came loose the 3rd time. Bent frame was not of my doing and came from Company that way. Had to pay $65.00 for repair. Still have not received the glasses and only hope others will inspect their glasses thoroughly upon receipt because Bushnell will find some reason to not stand behind their product. $170.00 purchase then $65.00 for repair with a 2 year warranty??????These are made of polycarbonate not glass as the web site states, one of the temples hits the inner bottom part of the lens and it's scratched already. They are either a fake or the description is wrong. I was expecting a lens made out of glass not plastic. Very disappointed!Sent an email to the vendor, this is the response I got:The Polar PHD lenses are made with Trivex material and built upon the NXT® platform. Which is:10% lighter than polycarbonateMore impact resistant15% lighter than CR-3975% lighter than glassNow that I know they are not fakes, I can admit that they are very nice, very light weight, I can barely feel them on my face, they gave me the option to return them but I've decided to keep them. I also changed the stars rating from 1 to a 4.It is excellent glasses have only one suggestion.Should be more careful of the manufacturer screws legs lenses for a month I was silent for a little screw these had to go to repair it. only that is otherwise excellent, very good better than other brands of high-quality vision also.The lens quality is amazing. I bought this to replace my beloved Serengeti Stratus. The only problem is that they feel a bit heavy and bulky. I miss my titanium wire frames. Maui seems to be the only company still making high quality frames, but I am loyal to Serengeti.The coating of the glasses started to flake off in the first week of wearing them, this led me to think they were a fake Item, I have given the seller the benefit of the doubt and ordered a replacement pair, hopefully it was a one off pair and the next ones will be good.Amazon replaced the glasses and it happened again, I could not recommend this product to anyone wanting quality sunglasses, this product was a big disappointment twice! I was refunded in full and will never buy this brand again.The lenses was made in plastic, i expected it was glass madeUnfortunately I bought these lenses brand Serengeti Flex Tosca Sunglasses and in less than a year they were put like they were cracked inside and I do not know how to claim because I spend more of the year someone could tell me if I can claim them thanks. And if they need photos I can send them bad articlesIf you are looking for good optics, this sunglasses are the best for driving. You will enjoy the clarity and definition of shapes and colors when you wear it.I have been buying Serengeti since the late 80s. They are amazing especially the Drivers.Although the colors look great and the glasses are comfortable , after a while I started observing a peel- off effect on the bottom of each lense .Excellent pair. I am vey happy with this purchase.I have and older pair of Serengeti sunglasses that I use strictly for playing sports. I love these just as much. I really like the style and the fit is really comfortable. They are also super lightweight.
