Backside AR on sunglasses

[drk]

How often do you do this? Is it a good idea? Is there an issue for you with quality?

[Kwill212]

99.99% of the time. No issues. I see more(but still very infrequent) issues with the factory front side hard coat than the backside AR.

What Kwill said.

We need to do more.

Do you do it on sport-style wrap frames, or more fashion and general purpose frames?

How about polar poly?

Yes.

Yes.

Is that the stuff I scraped off my shoe this morning that smelled terrible? I thought it was dog crap...

90%+ of the suns I do are polarized. 1% of those are poly and only for cutout/blank size in a huge sport frame or something like that. They all still get backside AR.

Be nice to polycarb. It's not polycrap.

All suns should have AR IMHO. If not, your not doing your best for your pt.

Yes backside AR EVERY sun! Spinning off from our discussion about tinting and AR drk, I rarely tint and always go for polarized (poly all the time, I have few issues). And on polarized Xperio is amazing: you get the frontside TD2 dip hardcoating, and Alize backside. And the price is excellent.

Even if you're not doing premium lenses/AR, I would recommend even a cheap backside AR. Most labs have a pretty inexpensive basic AR that will still do a good job of reducing that backside lens reflection.

The first step is admitting you have a problem. Drk, now the healing can begin.

I just can't not do AR backside! I ALWAYS recommend it. The only exception would be something where the frame is more like a goggle and no light can come in from behind , maybe then you can get away without it (think Liberty DE cup frames). That's pretty rare though. Myself... went cheap one time and skipped it. Drove me up a wall and I can never ever again have a sun without AR backside.

We were just discussing this in office! I always do a backside AR, whether polarized (99.4%) as well as the infrequent tinted only lens.

I've heard a school of thought that you shouldn't backside AR tint only lenses. Does anyone want to give me thoughts on this?

Sounds crazy to me. Was it in a fortune cookie? Who did you hear it from?

Referring to backside AR on suns

Yes some people do.

However it is another gimmick to make more sales for more money.

Who likes it best ...............the optician that sold it.

I respect the hell out of his opinion, does anyone know where that opinion is coming from?
