A lot of the disappointments with AR is simply because the US loves Spin Coaters, but dip coating (used in Europe and Asia) has 30-40% better durability. With the new smaller Dip maching by Leybold and Schneider, it could tip the scales toward more Dip coatings in the US. Old dip coaters were the size of shipping containers, not something for the faint of heart or those who wanted to actually walk around in their labs.
I agree that quality Dip Coating is the way to go, and I like Labs that use it. Dip coated Crizal Avance is the nuts.
However there are those that even the best AR is just not meant for. Although its not an technically an occupation I would like to add to the list: "People who do not, cannot, or WILL not clean their glasses."
You are doing them no favors by putting them in an AR, it will only be greasy and they will be hindered not helped. Put them in a thermal cured hard coat or just an EZ clean coating.
Years ago, I had an older Asian lady who purchased a very high-end frame and lenses with A/R. They looked wonderful in her high-end case and she loved them... until she put them on. She shrieked at all the wrinkles around her eyes, and we immediately had the A/R removed.
I have quite a few food warehouse people who stay away from AR because of the temp changes. We all just do the best in ourr experience to provide a useful value product to the patient. It's a judgement call. I just wanted to add that we are currently selling the snot out of those glittery Kate Spade frames, brought them in for fun/wow factor and they work on a surprising percentage of faces. =)
Actually you can also protect any AR against dust collection by using by applying my ZeroFog which contains anti static agents and dust will not adhere to it. Very simple solution and another sale.
just to sum up some of this
Would it be better to put the mechanics, welders, blast furnace operators and thoes who work around dramatic changes in temperature in glass? The farmers round here swear by it and even the welders that have slag blasting in thier face would prefer glass over poly or trivex for safety. For cooks and those that work around ovens or go in and out of a cold environment to a warm environment might appreciate the anti fog td2 or anti fog AR. For thoes working around hair and low to moderate dust, use the higher end AR (avance and saphire as was mentioned) with the oliphobic and hydrophoic coatings. Anyone that is in a costic environment that uses harsh chemicals or abrasive, destructive materials should probably have specialty saftey equipment on anyway and for thier casual eyewear use an Alize or better.
Glass can pit with metal workers and welders quite quickly, which becomes a enormous safety issue as the glass weakens appreciably.
I would put them in appropriate safety eyewear for their trade, but with Trivex or Poly.
