Best AR to stay stuck

[tntborden]

I have a 31yo nurse with a pair of synergy poly -0.50 OUs, twice in the last year she has come in with them pealing. She acknowledges that she is around chemicals ant work, but doesn't really have any control over that. They don't look to be scratched and she is fine with how they clean, so thats not an issue. So my question is this, what is the best AR to stay stuck to the lens without regard to the other AR issues?

First off, do not use poly for here. I use a lot of Airwear with Crizal (and Alize), and for most people it works, but it is not good for the harshest users. Considering that Airwear and Crizal hold up better than most poly and AR's, it says something.

I am not sure what here RX is, if it is -0.50 or -5.00. If it is regular -0.50 you can use CR-39 or Trivex. If it is -5.00 you can use trivex (which could be thicker depending on frame size, decentration and such), 1.6, or 1.67.

I like Super-Hi Vision, that has a substrant matching policy, and Crizal Alize. I am not saying that others will not work, but I have a very good idea that these two will. I would stay away from UTMC, maybe Teflon (just some members on their board said it peeled) and less expensive or no name brands in this particular case.

Someone here will probably argue glass too, which will hold up the coatings better, but then we have many negatives associated there.

Use Crizal Alize w/ clear guard it's hydrophobic as well and static resistant. So any chemicals in her environment will be deflected from her lenses. I am comfortable putting my 3 year old in this AR!

I wondered about Trivex. Do most AR's stuck to it better than poly. Does antone have any experience with Younger Trilogy Stock AR. I don't really want anything less safe than Poly, so I ruled out CR39 and glass.

Glass with AR
Never had a problem!
Sticks like crazy glue!

[Fezz]

Since you mention the safety factor(no plastic or glass) I would suggest Trivex/Phoenix. I have had great luck with Hoya Phoenix with Hoya Super Hi-Vision.

Although, glass will hold AR the best in my experience. I have a pair thats 5-6 years old...looks pristine!

If you want something really impact resistant, then use Phoenix with Super Hi

Someone help me out here...How is Airwear different than polycarbonate? Is there that much difference between 1.586 and 1.59?

[JerryR]

I would suggest using any of the premium AR's, Crizal, Teflon, Hoya etc. But i would make sure the substrate I use is made by the same manufacturer of the AR you select. Compatability of the hard coat and the AR is one of the most important factors for adhesion.

[tntborden]

Would it make it easier if I said that I would like to order these from my Nassau finish lens list

[MarcE]

why do you want to stick with Nassua? They are fine and I have an account. But you want to change lens materaial or coatings, right? Lenstock.com has almost every brand available.

The other answers are right on. I think poly is not a good choice for harsh chemical environment. Try the trivex with factory hi-vision, or 1.60 w/factory AR. My experience is that factory AR sticks better because the hard-coating is substrate matched. Synergy lenses are done at Nassua's lab, right?

Judy,
I don't think there is any difference between poly and Airwear. I think 1.59 is just 1.586 rounded up.

Please everyone, set me straight if I'm wrong.

[CuriousCat]

Just checking.

I think Airwear is Essilor's brand of poly. My understanding is that it does have a cleaner processing for better optics. I would also argue from example that it its processing of AR on the poly is better, as it is the only poly AR that I do not see constantly crazed.

[CuriousCat]

I guess I've just been lucky. I've been dispensing poly since the mid '70's when it was pretty awful. I've been dispensing poly with a/r since the late '80's and crazing has never been a big problem...or a little problem for that matter. Inso far as quality is concerned, with the rise of the CD industry, poly has improved in quality and clarity. With the exception of the SunSensor's mid-index that I'm wearing right this minute, all of my glasses,about 20 pair in my current rx, are poly and I have no complaints. In the words of Peter Graves, I'm one lucky woman. ;)

yea but Optima says that Resolution has better processing for better optics
Yea and Vision-Ease says that their Tegra has the better optics. And on it goes.

I can't tell any optical difference between "Airwear" and other poly; and I'm just type of geek to try to look for the difference. There are some unwitting test subjects in my town wearing "Airwear" in one lens and some brand that costs one third as much in the other

If you want to see AR that doesn't craze, order some cheap factory-coated lenses from Somo or Dagas. I would argue that most (not all) factory applied AR is as good or better than Crizal at 1/10th the price.

TNT:
If you are seeing crazing, you might want to ask if she is storing the glasses somewhere hot, like on the dash of her car.

I'm pretty sure you could boil those lenses and nothing would happen.

Sorry fvc20/20..................Totally false statement............................

AR coatings are all the same.............basic

SIO2 = silicone dioxide

Hydrophobic = polysiloxane

clear coat = polysiloxane

All of these I can remove within 5 to 8 seconds at room temperature in a solution of only 11.5% of an acid mix.

If AR coated lenses......whatever the make and whoever makes them will get into contact with the right chemicals or chemical fumes they will suffer and initiate peeling.................................

And all this has nothing to do what the underlaying lens material is.

I have never dealt with Resolution, pretty much because I do not know the quality of the coatings for it. I will say that I have got comments from people on optics when they moved from one poly to Airwear, and I never mentioned the difference.

I also have to argue your generalization on factory AR. I will not say that a factory AR cannot be the same quality as Crizal, but I will say that I have not seen one that has held up.

Airwear is made by the great Essilor, so it is obviously better than any other poly!:bbg: Just listen to them. These are the same people who swore to me that they didn't make LC's Duralens (Stock CR-39 with two-sided Ultrashield) until they accidentally sent me one in a True Tint package, and as luck would have it- it was a Grey3 sunglass tint. Except the DuraLens didn't tint.

This is what stood out in my thinking. The answer may well be right in front of us. Chemical environment and AR do not generally well together.

Apparently, the original thread poster works around chemicals that emit a vapor which affects her AR coating. I wonder what the vapor does to her lungs, kidney and liver? The solution is a location with proper ventilation.

The person in question is a nurse.........are you suggesting that she carry a fan with her on the job?

Your safety problems have been covered and rehashed on the optiboard many times over the last few years. Check the archives.

One does not sell AR coatings if somebody is around chemical vapours and fumes, it is that simple. Nurses have a mobile job and do handle some solvents on their job. Maybe you got to educate the hospitals to install better ventilation in their patients rooms.

This should work well for her!

Fantastic Idea.......................every optician should give away a hat like this with every pair of AR sold.............and wear them themselves when working in the lab..........problems solved :bbg:

[FVCCHRIS]

Great hat, mines on it's way! Thanks:cheers: Chris..
