I am having a problem with expensive sunglasses bought in the US
Are they only supposed to stay clear for a year or so before being replaced ?
I have a few pairs of Ray Bans and Serengetis on which there is some sort o f cloudy build-up on the rear of the lenses. Cleaning gets the glasses clea r again but the cloudiness comes back within a few hours.I have tried optic al cloths, optical cleaner and in desperation, Windex.
This doesn't seem to happen with less expensive glasses and the cloudiness doesn't appear on a pair of Serengeti tradewinds bought in Europe about a d ecade ago
Does anyone regognise this symptom and have a cure please?

You're probably buying cheap knockoffs advertised as Ray Bans. Have you thought of contacting the mentioned companies above with your problem?
Something strange that it takes hours for cloudiness to come back. I have regular glasses with anti-reflective coating and they seem to need cleaning more often but these are sun glasses and would not need such a coating that transmits more light.
There are other coatings like anti-scratch coatings or UV reflective coatings. It does appear that some kind of coating is there that tends to attract dirt or particles in the air causing cloudiness. Glasses would hold up much better with such coatings but have to be cleaned more often.
How long is your hair? Do you lift the glasses above your forehead when not using them? In that case, any amount of hair is enough. I do that, with regular glasses, and they are always getting dirty.
I've heard you're suppposed to wash them with soap and water, but I just wipe them with any cloth or soft paper that's available, even the top of my sock or a corner of a paper napkin. I don't think I get the hair oil off but I either move it to the outside of the lens or I spread it out evenly so that after I do that the image is clear as can be. It's good for... what was the time you gave? A few hours, that's it.
BTW, I've only been wearing glasses part time and only since I'm 50, so no one taught me any better.
Having read the rest of the thread, I'd go to an optician and ask if he knows what to do. No matter what, he'll probably sell you whatever he sells for cleaning lenses**, but maybe you can say you'd buy it if you knew it would work. Does he have an open bottle so you can clean them at his place, and if they still look good a day later, you'll come back and buy a bottle. (This assumes it's not your hair.)
**As cynical as this sounds, i still think some opticians will know the answer to this. Or they will look at your glasses and have something to say.
How could Ray Ban etc. confirm their authenticity without seeing them?
As to my personal experience, I haven't worn sunglasses for 10 or 20 years. Given that no one wore them until what, 100 or 200 years ago, I thought I could learn to do without them, and I learned. But now I regret it since I found out they can "help to" prevent cataracts. I'm 70 and don't have any trace of cataracts yet, so we will see in years to come if I harmed myself. (Hmmm. Since I thought about this, I still haven't bought or dug out old sunglasses.)
But whether they are el-cheapo Ray-Bans or el cheapo Serengetis, or whether it is a problem with the coating, what can I use to clean them off? If the specialised fluid used by opticians doesnt work?
Or is this Luxxotica planned obsolescence in an American-sold product? Which wouldnt be tolerated when the glasses are/were sold in Europe?
I think she got ripped off with some cheapie knock-offs whether she believes it or not. I've NEVER heard A-N-Y-O-N-E but her complaining of this problem.
Most glasses are a complete rip off. I buy top of the line glasses from Zenni Optical for $75. Comparable in US would be over $500 even though they are using the same frames from China.
Mine would be $230 from Zenni but for the $100 more I pay locally I'm sure to get a good fit. With my lenses, a 1mm difference is huge so I'm not ready to try them. With single vision I would.
To some extent, I agree. I buy lots of glasses from Zenni but they are hard ly top of the line! They are somewhat flimsy, conservative in styling despi te having a choice of thousands of similar looking frames, rarely have spru ng temples, are a bit iffy on the PD and VERY hit-or-miss on centering the lens to the eye. I did once manage to order a pair of vaguely modern frame s from them but they deleted the style pretty quickly!
I agree that Luxxotica makes el-cheapo RayBans to screw customers in the US market. I am a bit surprised that Serengeti does as well
