Hi, folks:
Does lens spray cleaner that contains isopropyl alcohol do any harm on AR, blue-light coating and Polarized lens?
It's a biodegradable solution.
Thanks in advance.

Never seen it happen, but one of many theories is that alcohol will "dry up" the AR coating. Not a very helpful answer, because I haven't found any facts to back it up.
Also interested in the answer though, has anyone noticed any effects from long term use of these cleaners?
I recommend people use alcohol only occasionally, not for the lenses but for the frame materials that may dry out.

It depends on what you're trying to accomplish. I use alcohol for the final cleaning of every lens that leaves my lab to make sure the AR slick coat is evenly removed. Using alcohol once or twice in the lab process is one thing; you want to discourage your patients from using alcohol every time they clean their glasses.

I just recommend against IPA if at all possible. I have had it eat a frame once (literally, into pieces in my hands). It gave me PTSD regarding IPA.
This is a good question and coincidentally came up at a good time. I have found that some cleaning wipes have a lot of alcohol in them and can ruin the finish on zyl frames. I have also heard, but don't know for a fact, that over time alcohol can erode the AR coatings. Therefore I have not recommended them to my patients. I tell them to be very careful with them and to use very sparingly. That being said, I just got a sample of cleaner from Caloptix and it is in a great bottle and works well but has a stong alcohol smell. Not sure if that is bad or not. I guess I'll have to have my lab check it out?
My advice- discussed with peers- is to use water or a lens approved SPRAY regularly,
Dawn dish soap for build up on lenses,
and premoistened wipes (containing alcohol) when traveling/ sparingly.
I've been taught that alcohol used regularly will damage coatings, especially cheaper ones, though I agree with AngeHamm that it is more important for the integrity of the frame.
The obvious advice of mircofiber or cotton and not paper products always follows.
Have I told you today how much I hate poly?
