Occupations where AR just isn't that good

[becc971]

So i'm getting a little flack from coworkers so I would like to get a little justification. or ripped to shreds, you know, whichever makes more sense

I sold a beautiful pair of glitter Kate Spade's to a girl the other day. that's right, GOLD glitter. We did NOT go with AR however because she is a dog groomer. all I could picture is junk on her lenses all the time, I feel like even the most phobic of hydrophobic coatings can't combat that career.

that being said, any other careers you guys would say AR is a bad plan?

[AngeHamm]

I can't say I agree. Her non-AR lenses aren't gathering less junk, they just have big white reflections that obscure the junk--as well as the dog, her clippers, the rest of the room...

[mervinek]

I still would recommend the AR...would be better under lights...but would warn her that she would have to clean them more often. Dog slobber and all that. Then it would be up to her. I love my AR and pretty much recommend it to everyone. EXCEPT...people working with chemicals... for example..mechanics and dusty environments like dry wallers and farmers. Around here the farmers get so much dust on their lenses its like they are sandblasted. Its coming at them all day long. There are always a few exceptions to the rule, but education is the key.

You know your AR best, becc. One of the ones I used to sell I'd fear breaking 40% of total spec sales and I'd agree with you completely. If you can move premium ones, I'd lean with AngeHamm--especially if they give the lenses an extended scratch warranty. Hair dresser with chemical clouds in his/her face every day--yeah I skip it. Unless a dog groomer uses as much hairspray on their clients: I wouldn't fear putting them in a Crizal Avance or Sapphire.

sandblaster operator?

[Tallboy]

Anyone who works with a blast furnace, Commercial grade BBQs, or roofers.

[MikeAurelius]

Metalworkers, welders, machinists.

[MikeAurelius]

Anything with an abrasive environment. If a plastic lens won't survive the abuse, neither will a coating.

[mervinek]

I think we all know those patients that are "Trivex only" patients. I try to flag their records!

I take my lenses off every time I open a hot oven. I suspect that over time, blasts of 400 F air are not going to be good for the AR coat.

[SeaU2020]

anyone doing a lot of outside construction

[HarryChiling]

Car mechanics, especially if they work on brakes. Lots of grease and brake cleaner will strip coatings.

[Paul Smith LDO]

An office worker who uses 100 grit sand paper to remove surface curvature for better clarity at the computer.

[Fred Dagg]

Probably about 10 years ago I had a pt with repeat coating failures. Like every spectacle wearer in the history of the world, he swore he was treating his glasses exactly as instructed, but I actually believed this guy. It turned out he worked in a Supermarket, and was going in and out of walk-in freezers all day. The rapid changes in temperature caused his coating to fail. As I said, that was a few years ago, so newer coatings may handle this sort of situation better. Still an interesting case though.

On on coatings generally, always go for a good one. Cheap coatings are a hassle for pt and practitioner both.

I tell patients I'd rather they get nothing rather than get the 'basic' AR. It's hard to clean and easy to scratch. I don't like to sell problems.

The list of occupations who shouldn't have AR is a very short one.

Based on the above, I'd say it's getting pretty long.

BINGO
and oil burner mechanics who use lots of wd40

[Chad Sobodash]

Professional baker or pastry chef. Staring inside an open oven door all day long will annihilate AR.

Edit: but this is just an opportunity to demonstrate to someone that they need two pairs. A good titanium pair with trivex and a hardcoat to leave at the bakery and a comfy plastic pair with high index and really good AR.

Amen.

Most modern AR coats have significantly higher Bayer and other durability testing scores than a plain old factory hard coated lens. As such, those AR coats would actually be more durable that a plain old lens.

Of course, if the environment is that dusty, you probably should refer to Annex I of ANSI Z87.1 (Selection Guide) for help in selecting the proper protector, which might include goggles.

[EyeManDan]

plumbers, gasses from pipe glue can break down coatings

I have found printers don't like it because of the dust.

[King of the Lab]

Normally Id say no AR to anyone working in a High Heat environment or anybody that works with any type of aerosol/ corrosive chemicals that can consistently ruin their coating. That being said, my office offers a 2 year unlimited warranty on our Crizal Avance coating and say what you want to say, 90% of our patients don't abuse this warranty and it has worked out just great.

THIS was the conversation we did have, and she is coming back as soon as i can find something equally awesome

Tombstone finisher. We finally gave in and put him in glass.

Happy October!
