    Does lens cleaner w/ Isopropyl alcohol damage Blue Light, AR or Polarized lens?

    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?

    Not alcohol but high concentrations of ammonia over long periods may.

    I recommend people use alcohol only occasionally, not for the lenses but for the frame materials that may dry out.

    That's a solid answer, thanks for the reply.

    So it's best that we use the alcohol-free AR lens cleaner instead of the ones come with alcohol?

    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.

    Yes, that makes sense.

    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.

    It would depend on the concentration. Cleaning AR coating with isopropyl alcohol based cleaners can degrade the hydrophobic or oleophobic layer's bond to the subsequent SiO2 layer over time. Soap (Dawn dish soap) and water is always your best option.

    dish soap? I think it have too high pH and that can damage the Ar

    Many lens cleaner have Ipa in low concentration I think it is safer...or go to with hand soap

    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?

    When I got the original Reflection Free AR in 1990, I hated it so much that I removed it by simply soaking the lenses in alcohol for about 15 minutes. But I don't think you need to worry about that with new ARs.
