Hi, my name is Wily and I am a Revoholic!
I have worn Revo's almost exclusively for decades. Last count, I think I had 18 or so, but I will put together a photo collection sometime this week! I can say without any doubt, that I have lost at least half a dozen of these fine shades over the years (along with some Wayfarers, other Ray Bans and a couple of nice pair that I can not remember the brands of, but they weren't cheap). Favorite ever was the Revo Half Moon, but lost that pair in an accident. Another gem was when I bought two pair in pilot style, one with green lenses other with purple lenses, swapped one lens in each and gave the second pair to a friend. He still has his, mine were lost ;~(( I can say, I have not lost a pair now in MANY years (then again, my life is markedly tamer these days)!!! I used to get prescription Revo's, but when Ray Ban (technically, I believe it was their parent company Luxotica) bought the company in the 90's, they stopped the prescription program for many years. My optometrist (who made custom eyeglasses for Andre The Giant) convinced them to make one last pair for me after the program ended which they indicated would be the last pair they would ever make (but they then revived the program years later and I don't think Luxotica still owns them).
As their old advertisement read "The world looks different through a pair of Revo's", or something to that affect, and I truly believe it. Optically great lenses, mediocre to boring/stolen frame designs (otherwise I would likely have a lot more of them). A few years back, I got a friend addicted and he now has a couple of dozen of them ;~))
The reasoning behind my addiction is the UV protection these lenses provide. You will see in the drugstore, the $5 sunglasses saying they have 100% UV protection, but that is UV-A they are referring to. Revos block that and a large amount of UV-B and UV-C as well (which some say are the more harmful UV types when it comes to your eyes). Developed by a scientist from NASA who used the technology he/they had created for satellite and space helmet shield protection.
To be continued ;~))
