they aren’t made well. It has this weird beveled section so when you look down it distorts everything. Can’t wear.
I purchased my first pair of Serengeti Aviator Drivers >30 years ago. Since that time, Ie experimented with other name-brand glasses (Oakley, Xezo, etc?, as well as a number of highly-touted newcomers (always the next greatest thing!)After all my tries, I alway come back to the tried and true Driver lenses for what I believe to be the best road presentation available.I won rand?myself as a Serengeti expert; however, I would like to cover what I believe to be a few misconceptions and/or errors in other reviews.These are very high-quality GLASS lenses ?if youe prone to drop your glasses on pavement, these likely aren the sunglasses for you. [Ie read some reviews that show 1 or 2 stars because their glass lenses broke when they hit the pavement ?really?!]Also, there the debate about polarized vs. non-polarized. Please note that Driver non-polarized lenses allow 8% more light through when lightened, and 2% less light when darkened. In other words, Driver non-polarized are brighter on dark days, and darker on bright days ?that the reason I choose non-polarized in my main glasses. [HD Polarized?are closer in performance; however, theye also higher-priced, and not available in the Medium Aviators.. ]radient?simply means the lens is darker at the top ?it doesn mean the lens darkens on bright days ?that hotochromics far as edium Aviator Drivers?(6826), they are photochromic, gradient, non-polarized lensesPossibly a bit confusing; however, the website does a great job of covering all their products, including technical specs.One other point to discuss is how the glasses have changed over the years ?some say theye heapened?I disagree. Yes, they lighter, but that mainly due to improvements in the lenses, and the lightness (at least to me), makes them more comfortable on longer trips.Quick summary is these are very high-quality lenses, in a very atrtractive frame. They come with a super-quality case and cleaning cloth, and are the result of many years?dvelopments and improvements ?highly recommended.Using these as wedding gifts for guests. Cheaper sunglasses but what I expect for this great price!.
