Crizal Alize with Clear Guard-Wow

**Happylady** · 02-14-2006, 04:31 PM

My husband's new glasses are so easy to clean. I cleaned mine with Teflon and then his with the Alize with Clear Guard and the difference was amazing!

I do understand there is a new Teflon AR coming which is supposed to be better.

We have had our first few jobs with it. Seems nice. As far as slipperiness goes I cannot tell the difference. But nice to see Crizal update it, because they really did not have to.

I think when you get right down to it, Alize w/ Clear Gard is simply Alize w/ anti-stat. Teflon has had an anti-stat layer for some time. The "slipperyness" would not necessarily be affected by the new "Clear Gard" process.

I would simply caution that "slipperyness" is but one feature in the overall performance of an AR lens and, at a point, hard to really differentiate.

The Alize with Clear Guard is vastly better then my old Teflon lenses. I can't believe how easily they clean. And they really do stay clean longer.

Well there are other features too. Scratch resistance, but Teflon, Alize, and Advantage are comparable in that realm. Super Hi leads that area. Saying that, I do not get scratched Alize lenses back in the store.

Duriability is another major feature, and all four of the named ones seem to have that.

Light transmission is a unique feature. Advantage and Teflon both have the blue coating in the US which, on average, allows more light transmission. Question is if it is a meaningful amount. Also, Alize has the blue coating in Canada and I think the rest of the World.

Ease of edge is a thing. Teflon you need nothing to cut them. Alize has the protective coating. Super-Hi and Advantage have stickers, which can be a pain. HOWEVER, this point is only valid if everything else is equal.

Anti-Static. Another nice feature, but only a bonus. Teflon and Alize both have it now. Super Hi and Advantage does not.

So now we come down to the last thing. Ease of clean. Sounds like the Advantage is great, and the Super Hi is very good. But Teflon is terrible compared to the others, and I hear that Alize is the best.

For these variables I will rank them on imporantance:

1. Duriability
2. Scratch Resistance
3. Ease of clean
4. Ease of Edge
5. Residual Colour
6. Anti-Static.

Stock poly w/Alize in minus lenses are very susceptible to crazing, during edging AND also when handling with difficult frames, not the Advantage w/AR. At smaller eye sizes, poly flexes very easily and causes the Alize to craze. This may be due to the different coating applied under the AR. I am very weary of using this product in drill mount frames, where the lense is under constant stress. Lense materials other than poly have not been a problem.

with Airwear Crizal you just have to make sure that you put a pad on both sides, use low pressure settings and use a chuck size that matches the pressure size. Do that and they will not craze.

Tha lenses can craze when flexed during handling. I do not have confidence in the AR stability in certain frames, drill mounts especially.

hmm, never had that problem before and I use a lot of it. Sounds like something you should discuss with the lab who coats it.

Actually there is a "CRYSTAL CLEAR GUARD" that does the same thing and some more............like anti-fog.

It can also be applied after cutting the lenses, so you will not have any slippage problems........and you purchase the lens without the extra topcoat and apply it just before mounting the lenses.
