Let me get this straight. You are proposing to dip some lenses in a caustic solution that may or may not remove the AR coating without screwing up the lenses or causing you to come down with some dreaded disease all to save your customer a few bucks of money?

What are you thinking? What are you smoking? Are you off your meds?

This is not a proposal, I have sold AR strippers for CR 39 lenses since 1984, when Essilor wanted to sue me because AR coatings could not be defective.

There are no caustic solutions, they are acids that dissolve the layer.

The largest users are the coating labs, plus some smart opticians that sell a new pair and strip the old ones to tint them as sunglasses, or leave them just as a usable backup pair.

You need not to smoke anything or have to be off your meds to understand that there still some people that can not afford multiple pairs of glasses from their B&M opticians.

This is a great option to have for people to save a set of lenses that are in good condition but have a broken down AR on. Many of our patients have this done to a worn out pair that they can then keep as a back-up.

Not seeing why this is outrageous when everything else is the lab is a breathing hazard as well. Honestly, I should wear a respirator all day if I want to be fully protected. Fumes from the tinter give me more trouble than AR stripper.

When it comes to saving the patient money- we certainly don't offer lenses for 'a few bucks.'

Speaking of AR... I just had a patient (got her glasses at a local chain store P**** Vision) and said she had clouding of her lenses and had to have them redone. She was told that the "lenses were baked in the oven too long and that's what made them go cloudy." They said they would re-bake them for her. Wha???? So she showed me the "re-baked" lenses and they had a few scratches on them. However they were "re-baked" so she shouldn't have any scratches. Have you ever heard of that as an explanation for crazed lenses???? That was an absolute first for me.

I arrange an against intelligent remover from Hilco it functions admirably on the vast majority of the cheap.

I would say that the were Polycarbonate lenses dipped into an AR Stripper. That is what they are doing.
