The lenses are cheap and so is the quality. The coatings usually peel off within a few months.

Try them for yourself...

I have been using them for a year and no issues.

performace DS aren't that bad, but the normal luxar coating is only okay, have problem before but their warranty is pretty good. use the luxar U coating.

I have been using Luxar and Luxar u for a couple of years. I find the coatings scratch easily and often break down. The break down is noticeable where the patients eyebrow or cheek touch the lens. The coating does not do well when in contact with perspiration. The lab has stood behind the 2 year warranty. Although it is a nuisance for the patient to return. The warranty jobs also costs me more more staff time and wear and tear on my edger. Currently 25 to 30 % of my daily orders are warranty claims. Does anyone else find these percentages at their practice or are these returns excessive? Thanks Mandy

That's a very high return rate. The national average is around 7%. Are the warranties due to the coating quality or Rx changes, non adapts?

The returns are mostly coating problems. The greatest amount of breakdowns are with the Luxar coating. The Luxar U has fewer problems. The Ultraguard (SRC) has fewer problems than the Luxar U. But all in, I am still having 25 % returns on coating breakdowns. The non adapts are very few ( likely in the 1 % range). Most coating breakdowns occur after a year, but some have returned in as short as a month or two. These returns are not due to mechanical (heavy scratches) or chemical abuse. I am looking for a supplier that has good quality lenses. But every sales rep I speak to claim this will never occur with their lenses. I would like some advice as to which supplier has a reasonably priced progressive that comes with a good quality AR coating.

Thanks Mandy

Don't listen to sales reps...most are only concerned about their sales figure and will say anything. Fact of the matter is, this can and will happen to any lens on the market at some point, however the frequency should be rare.

My best advice is to call up as many labs (big and small) as you can, get a quote, have them visit you in person and give them all a shot at earning your business. Order from all of them for a month or two. This way you can measure the success of the supplier, delivery time and quality of their lenses.

And if there's something unforeseen that develops, you can make the necessary adjustments quickly.

We use them a lot in our office at first but now we dispense Zeiss. I would say more than 25% come back for coating failure from optik k&r lens product. It is affordable but I rather give my patients something of better quality for a little bit more in price.
