2017 Eclipse Blog / FAQ – Are your eclipse glasses safe?

We are getting this question a lot, now that the news media has come out with lots of stories about counterfeit or knockoff brand glasses, and the dangers of using glasses that do not meet the ISO 12312-2:2015 standard.

We don’t know what you’ll get with other companies’ glasses, but we can tell you that you’ll have no problem at all with the ones you purchase from  (provided you follow the instructions printed on the glasses, and the instructions linked to on our orders page). is on the American Astronomical Society’s list of Reputable Vendors of Solar Filters & Viewers!  You can’t get a better endorsement than that!

ALL glasses sold by are manufactured by American Paper Optics and Rainbow Symphony – two companies NASA recommends as top-notch in the world, whose products are fully ISO certified.

These companies were the first to submit their products to the testing labs following the adoption of the ISO standard in 2015, and their glasses were found to exceed all the standards for safety.  In fact, the ISO certification for them was simply a validation of the high quality their products have ALWAYS had – all the way back to the beginning of their operations.  Oh, and we get all our glasses shipped DIRECT from their USA factories to us – so there’s no middleman at all to take a chance on.

If you’d like to hear a discussion about eye safety with Mark Margolis (of Rainbow Symphony) and Dr. Ralph Chou (the world’s leading expert on eye safety, who WROTE the ISO 12312-2:2015 standard!), check out the eye safety page in our Eclipse Roundtable.  (In fact, check out all the pages in the roundtable – it’s a great discussion!)

I personally know the owners of both American Paper Optics and Rainbow Symphony, I have used their glasses at all 12 of the total eclipses I’ve observed, I respect them as honest businessmen, and I trust their products to be used by my family.  That’s why they are the ONLY products sells.  If you follow the instructions, you’ll be perfectly safe!  Have a great eclipse!

Dan McGlaun, CEO (Chief Eclipse Officer)


  1. YOU WILL BE ABLE to see the filaments of incandescent light bulbs through SAFE eclipse glasses. You will also be able to see the arc from welding torches.  And, you probably could see the sparks from a Thermite reaction (though I have no personal experience with THIS!) WHY?  Because these are as hot and bright as the SUN!!!!!  But, the Sun also has dangerous levels of UV light that the eclipse glasses filter out – they are tested at more wavelengths than just the visible ones!  So, if you have glasses that came DIRECTLY from APO or Rainbow Symphony, you have the best in the world.  There are none better, and they will protect your eyes if you follow all the instructions.
  1. began selling eclipse glasses from Rainbow Symphony and American Paper Optics before those manufacturers started stamping the glasses with the ISO certification number. Rest assured that all of the glasses from those two manufacturers that we have sold meet the ISO safety certification standards, even if the ISO number does not appear on the glasses.

If you still have concerns, please return the glasses you bought from us.  If we receive them back prior to August 21, we will give you a full refund!

    My glasses have a number RoHs CE EN71 a triangle with 04 in the center and PE-LD underneath. Are these glasses safr

    • Admin says:

      I do not know what any of that means, except that the CE standard was the European standard. How old are they, and who made them?

    • Jon Anderson says:

      The markings of “RoHs CE EN71” indicate that the product has passed testing for making sure the materials are safe and compliant with the international standards, specifically ones applying to products sold in the US and in Europe. An Internet search for the term will have found the information quite quickly. Did you perform an Internet search for that term?

  2. Daniel Andrews says:

    Is your company an American company? Looking at your time stamp it says 7:10pm Next question, are you sold out?

  3. Paula borland says:

    Do your glasses have ISO number and manufacturer (Rainbow Symphony) printed on them?
    I recently purchased and returned viewers printed with manufacturer, Rainbow Symphony, but no ISO number.

  4. Roger Davis says:

    I’m reading all of your instructions regarding your glasses and the mandatory ISO standard 12312-2:2015. YOUR OWN glasses do not have ANY ISO number printed on them!!! I’m looking right at them, the tube I still have them in has your return address. YOUR glasses do say that they’re made by Rainbow Symphony but again, NO ISO anywhere! Lots of other numbers and credentials. Isn’t this a big strange?

    • Admin says:

      You are looking at the back of the glasses, and do not see where the ISO cert is printed to the left of the left eye lens? Rotated 90 degrees? All glasses we’ve sent out in the last year have this!

      The glasses are manufactured by Rainbow Symphony, so they are perfectly safe.


      • Gary Lambesis says:

        You state that all glasses you have sent out in the last year have ISO Cert stamp but I bought 10 pair 6 months ago and mine are identical to your photo except… NO ISO Cert Stamp. So, obviously all glasses you have ship DO NOT have the ISO stamp. Are these safe?

        • Admin says:

          Gary – Please email me a scan of what you have.

          ALL glasses EVER sold by have come directly to us from the two leading manufacturers in the world: Rainbow Symphony and American Paper Optics. They are safe to use, if you follow the instructions. Please read our blog post on this:

          If an endorsement of our site from the American Astronomical Society is not proof enough for you, then I don’t have anything else to offer. We tried to warn everyone of foreign counterfeit knockoffs…

    • Admin says:

      ISO cert

      Is this what you’re looking for? 🙂

      We get them directly from Rainbow Symphony! is on the approved list of eclipse glasses vendors published by the American Astronomical Society.

      I don’t have anything else to offer you…

      • Norma Smith says:

        My glasses arrived today and they have NOTHING printed on the inside to show any ISO number or that they were manufactured by Rainbow Symphony as shown in the photo on this website…..the inside is complete WHITE on all ten of my glasses. Not too happy and wondering now if these are not safe????

      • Norma Smith says:

        PS – in tiny print, the glasses do say they are made by American Paper Optics, LLC and CE ISO but no other numbers.

      • sarah says:

        I also have glasses purchased by my father probably a year ago he says from your site. they do not have the iso number on them to the left of the len on the back – it’s blank there. otherwise they look identical. i see that other people have had the same issue. were you ever able to verify that rainbow symphony made some glasses without putting the ISO stamp on them????

  5. Debra says:

    What about the fires currently in OR? how will they impact the eclipse in and around Mitchell, OR?

  6. Mel says:

    I bought 100 glasses from your company, but I can see light bulbs and sunlight streaming through the window through them. Other glasses I bought, also made by Rainbow Symphony, are completely dark. I am wondering why the difference and if they are safe.

    • Admin says:

      You can indeed see the filaments of light bulbs with them – as well as the bright arc welding arc. This is normal, because those things are essentially as hot as the Sun, and the glasses are safe!

      Please remember that eclipse glasses filter out invisible yet dangerous radiation as well. They are tested at multiple wavelengths, and so it is not just the visible aspect of filtering that is important.


  7. Luanne says:


    I see you’ve answered a question that was posted after mine. Mine says it’s still waiting for moderation. Is it because you’re not sure whether you’ll have more glasses in stock? Please, I just need a straight answer. I want the best eyewear for my family. I’d prefer to buy it from this site but need to know whether to go elsewhere so that we don’t miss out. My in-laws are in the path of totality and I’m tasked with getting glasses for the whole family. I don’t want my name to be mud!!

    • Admin says:

      I’m sorry, we’ve just had to be very careful with inventory in order not to take orders we couldn’t fill. We will be up on Sunday 8/13 at noon, for 500 more orders using Express Mail!

  8. Donna says:

    I wear glasses for distant sight. Do I place the solar glasses in front of my glasses for viewing the eclipse?

  9. I have glasses that state and are printed with the ISO 12312-2 on them. Are these safe glasses to wear or do they HAVE to state the whole number ISO 12312-2015?
    They also state that they meet the Transmission Requirements of AS/NZS 1338.1:2012, if that means anything to you.
    Are these safe glasses to wear during the eclipse?
    Thank you,

  10. Susie says:

    My glasses have ISO EN 71 printed on them. Can not see a thing through them except the sun but how do I know if they are safe? No 12312-2 printed on them.

  11. Allison M says:

    I just purchased a large quantity of glasses from TSE17, and they have a ton of certificates posted that appear to be legit and meet standards, yet on NASA’s site in parentheses they say “foil filters”. Are the glasses still just as safe since their certificates indicate so. I appreciate the help and clarification.

  12. Carol says:

    I purchased Britenway glasses from Newegg online for my students. They have the ISO logo and state they meet the transmission requirements of ISO 123122-2. Also meet EN 1836-2005+A1:2007 (E) for an E 15 filter for the direct observaqtion of the sun. Also meets AS/NZS 1338.1:2012. Please tell me if these are really safe or not.


  13. Kris says:

    Hi –

    I purchased by glasses through you, so I know they’re safe. I thought glasses were pretty much ‘one size fits all’ but I’ve been reading elsewhere that there are glasses made specifically for children & they shouldn’t use the “regular” ones. We’ve got an 11 & 9 year old in our group & I want to make sure their eyes will be as protected as ours using the eclipse2017 glasses or do we need to scramble around to find different ones? Thanks for your help

    • Admin says:

      I know of no “kids’ size” glasses. 11 and 9 should be old enough to use the regular glasses. Just make sure both eyes are protected by the lens material at all times when looking at the Sun!

  14. Lisa says:

    I bought eclipse glasses from you (actually twice since my numbers to my party increased!). They are made by Rainbow Symphony but do not have the ISO numbers to the left as you show in the question above. It does have one the right side the following “Meets the 2012 Transmission Requirements of EN 1836:2005 & AS/NZS 1338:1:1992 for Eclipse filters. (Queensland Directive).

    Are these safe for me to share with my guest?


  15. Greg says:

    For those stuck with counterfeit solar glasses, would it not be safe to wear 2 or 3 of them ‘sandwiched’ together? – just asking

  16. Helen says:

    We ordered glasses from a reputable promotions product vendor, Lincoln Line, although they aren’t listed on the safe vendors list. These glasses are certified ISO 12312-1, and the company is working on getting them 12312-2 certified, but the only lab that offers that testing is quite backed up so it may not be cleared before the eclipse. I also noticed they don’t have the silver appearance on the outside of the lenses that the media is telling people to look for.
    Is the ISO 12312-1 certification still a decent amount of protection, just not the top level of protection that NASA endorses?

  17. Mary says:

    I received solar eclipse glasses from Newegg. They are apparently outsourced through BriteNway and today I received an email from Newegg stating “Newegg has not received confirmation from BriteNway that its product meets such safety standards. Because of this, we strongly recommend that you DO NOT use this product to view the sun or an eclipse.” The glasses do have the proper ISO 12312-2 printed on them. I have put a pair on and looked at various sources of light in the house and they are totally black while looking through them. I put them out and looked at the sun through my window for a few seconds and it was visible. Since I was planning to share them with my grandchildren for viewing at school (we are not in the direct path but a short distance north), I am wondering if they are indeed safe to use.

  18. John says:

    Thanks for your work telling us about this eclipse!

    I bought 2 sets of glasses from you, first in August 2016 then in Dec 2016. I just noticed that they have different lens/filter elements — the December glasses have a reflective surface like mylar and the August glasses are just dark. They all have the same ISO numbers and print info on the cardboard area. Are both types of glasses equally safe?

    Thanks for the help. You must be overwhelmed with questions; I hope you can answer mine…


    • Admin says:

      They are both equally safe, because they were made by Rainbow Symphony. This company has produced safe eclipse glasses for upwards of 20 years. Follow all the instructions, and the glasses will pose no problems for you!


  19. Charlote Hinckley says:

    I received my glasses from in 2014. They do not have an ISO number. What can I tell my family to assure them of their safety?

    I put them on and looked through them at the sun and didn’t experience any trouble the next day. That may not be enough for these folks. Would you be willing to send me a personal email saying why the ISO is missing?

  20. David says:

    Is it the uv rays that are important to be knocked out to be safe?

  21. Charlie Powell says:

    We are headed to Nebraska, and will arrive on the 20th. We started planning this 6 months ago. My son bought me protective glasses for Fathers’ Day. Then he heard from Amazon tha the the glasses ‘were possibly’ not as protective as they had advertised. They refunded his purchase….as they did to millions of others (one of the biggest errors in their history). By the time I found out, nothing was available. It concerns me that these glasses (many purchased in multi-packs….8, 10, etc) have been given a away to millions of others. Even Amazon’s re-stocking products are not available in time for the event. Probably the biggest contribution to youth eye (and adult) problems in history. Cannot
    believe the media hasn’t picked up on this. We will have 2:30 min of totality at our spot….and will photo graph only then. We will use the pin-hole technique to watch the early and later phases. Will be interested to see how many don’t use protective glasses.

    • Admin says:

      You are wise to use pinhole projection. This recall has created one of the biggest blights imaginable on the reputation of our wonderful hobby of eclipse chasing. We tried to warn everyone. There are just too many glasses out there that were manufactured by the most experienced, CERTIFIED companies doing it the right way. Maybe this will be a good lesson for 2024.

      Clear Skies to you on eclipse day!

  22. I bought glasses and was told they are from American Paper Optics, though that is not on the glasses. I then noticed the ISO number is slightly different. Pair I have ISO12312.2-2015 instead of
    what I found on line ISO12312-2:2015. A dot and dash in one and a dash and semi-colon in the other. Please let me know if that small different is a big problem?

  23. Ken Coggins says:

    Thank you for this blog. I am an Amazon Prime member and purchased glasses from two different sellers only to find out that both sellers were not selling certified glasses even though advertised as CE and ISO certified. Both orders were “recalled” and Amazon promised to refund in the form of a credit to my account. So unless I purchase the inflated priced glasses with new money, I will not get them at all. The refund credit can only be used for some other Amazon purchase. I think that this is what is called “Bait and Switch”. Interesting that Forbes and AARP published the warning on Aug 3, just after the Aug 1 price increase from all mfgs. Amazon waited until the 13th to post the warning and stop selling the bogus glasses. They still have my money and surely did not pay seller, so Amazon wins. From what customers are saying, they are now getting counterfeit glasses. The seller now claims my glasses were tested in a lab in China, producing a document when I questioned them. They do bear the right marks. I tested them using the flashlight on my phone and they looked fine. Still not worth the risk, I’ll stream the event on to my HD TV with Chromecast and watch on mobile device with NASA app. Much better since I only get partial eclipse in my area. Found out how to make view out of cereal box along the way. This has been a 3 week adventure in eCommerce and astronomy. I now belong to a world-wide sky-watchers club(Shool) that will broadcast live coast to coast. Got a VR headset with remote from Amazon for $8 to watch the VR video from “I tell myself the value of the experience is in the journey. Life goes on,” -Jennifer Johnson-Intern-NASA Education Associates Program. I think the Chinese said it first, but I can’t certify that. Keep looking up.

  24. Barb says:

    Is there another company with a similar name to yours? I received mine from Eclipse 2017. They have the ISO stamp but no number. After some research, I discovered they came from a company called low cost merchants. They pass the light test. Can’t see any light at all except sun and cell phone. Have you heard of this company? I’m guessing they are different from you?

  25. Kim says:

    Can these glasses be used for future sky events? Is there a time frame when the lens in these glasses are no longer safe or usable and must be disposed of?
