Amazon recalls eclipse glasses

If you put them on during daytime you can see indirect sunlight and even my kitchen light. They were shipped from China despite having "Made in the USA" markings and all the proper ISO certification fine print.
I haven't received any communication from Amazon, so people who haven't heard from them should not assume their glasses are safe (contrary to Amazon's statement). I contacted Amazon support and they were quick to initiate a refund. For some reason Amazon rejected my review warning that items from third party sellers may be counterfeit and explaining how to tell.
Here are a couple photos of the counterfeits: https://goo.gl/photos/1XRKw8KBgo3hjHx6A
I feel bad for people about to be injured. But hopefully this will screw Amazon hard and make them change their ways.

Parts of China is pure filth. There is no quality control until bad PR surfaces. Then it's all about saving face.
So it wasn't a case of adding deadly poison, it was a case of adding an almost safe ingredient because the manufacturers needed to get their cost down to compete. Amazingly, it appears that melamine was even too expensive and they bought scrap melamine from the manufacturing process which was not pure enough to be used in plastics, beacuase it contained the actual kidney damaging chemical rather than just the precursor.
Lots of detail in the Wikipedia article: https://en.wikipedia.org/wiki/2008_Chinese_milk_scandal
Just because only six babies died from acute kidney damage (according to the article you linked, which does not quite agree with your numbers) does not mean that's where the damage ends. Evidently there were 54,000 babies who were impacted severely enough to be hospitalized -- that's 18%, a far cry from 0.001%, and most definitely not an indication that an ingredient is "almost safe". Ignoring 53,997 of them makes your analogy incomplete to the point of being specious.
I'm wondering how these practices have been able to go on without any reports of poisoning.
I'm a lot more concerned about potential counterfeit medication than I am breakfast cereal.

If I recall correctly, the process for Grocery and H&B have the same requirements. I am ungated for both.
So yeah, point of the anecdote: even veteran Amazon shoppers can forget how the site works.
Your email to Jeff had no effect whatsoever.
I assume your understanding of Amazon is from a consumer perspective only?
You're right, though I did get a $30 credit out of it.
> I assume your understanding of Amazon is from a consumer perspective only?
Yes, but I'm generally aware of how Amazon works behind the scenes as well. I know the difference between FBA and MF Prime, but even so I had managed to overlook it until the item arrived and my wife had already sent the email.
A company I've never heard of, but one that NASA specifically recommended as safe, and that Amazon was supposed to verify as the real manufacturer.
Be careful!
Guess I won't be looking at the sun :)
And it may happen to be that blocking the visual with the counterfeits also blocks the invisible wavelengths. Or it may not.
There should be some statistical evidence provided.
I did read from one of the recommended manufacturers that they tried to warn Amazon about this for months. They also tested them and they appeared safe in the tests they ran even though they were not legitimate.
But only Amazon knows what they have actually sold.
I don't mean to say that people shouldn't take safety seriously - just saying that it's interesting how we used homemade solution to this and don't have any (obvious) sight problems.
arc welding gear is generally around 10-11.
many newer electronic helmets go up to 13/14 which is enough, you have to remember to turn up the sensitivity on the sensors so that its always dark. otherwise it will stay open at around 3-4

See the photo at the very bottom of the page for an illustration of the (very minor) differences.
The sun still hurts my eyes if I look close to it so.. looks like I'm out of luck.
Any chance you can share a link to the item?
https://www.amazon.com/gp/product/B01N9T9CZL
The seller that sold me the glasses is no longer listed. The only remaining seller is the actual manufacturer.
The Amazon seller, GSM, assured me in a comment that if in my order history GSM Sales is listed I should be good to go, and it is.
I don't believe mine shipped from China or anything as they were ordered with other Amazon Prime products so I'm not even sure how that would work.
This is apparently the source of the glasses although the seller was third party. I don't want to toss out perfectly good glasses because Amazon freaked out and banned anyone not on an exclusive list of suppliers.
The Eclipse is 1 week away after all
AAS approved - https://eclipse.aas.org/resources/solar-filters
Someone on this video (https://www.youtube.com/watch?v=7Jmdo5jJIeQ) got this ISO certification - https://drive.google.com/file/d/0B5zcT8x8808gOE82aks3NUpPSTA...
Another product page - https://www.daylightsky.co.uk/collections/eyeware/products/p...
I think they might be safe enough.
Update: Looks like the seller "Tried and true products" is Joseph Harwood, who works at this company, https://beta.companieshouse.gov.uk/company/09572536/officers which owns the trademark Daylight sky, https://trademarkalertz.com/owner/DE-BIRD%20LIMITED "Tried and true products" also sells de-bird products. I guess they might just be sister companies or something.

And where do you think that place got their glasses from?
I could write a book re: Fake China.
I'm leaning toward throwing on an ordinary UV blocking pair of sunglasses on top and then limiting my time anyway, you can basically see the same thing with the pinhole technique. This is a risk I would take for myself, if my children were still young I would not risk their eyes, nor do it in front of them and tell them they couldn't.
Also, I can distinctly remember staring directly at the sun as a (dumbass) kid on multiple occasions for as long as I could stand it.
Yes, nature has made it so that we can't do that and harm ourselves, since the sun has been there for a long time. The problem is precisely that during the eclipse you'll be able to "stand it" for much, much longer. Eclipses don't happen often enough for us to be protected against them, and I also have to imagine most animals aren't as fascinated with them as we are...
Source: I received the emails, read the article, and at least one of the products I received is certainly not counterfeit.
I have received a counterfeit product from Amazon and I thought they were going to handle it excellently, but then they dropped the ball asking me to return a dangerous item to the seller for them to pass it on to the next person. I refused and fortunately got a refund, but all the effort was on me.
Amazon's sku and bin level accounting works perfectly fine for items that have a single origin. Shoehorning commingled inventory into that same system doesn't work. It was reckless, and they should bear the punative cost for its results.
If so, it has a very low amount of problems and complains, since they could grow so big. If bad suppliers were a constant, they would be bad-mouthed enough and wouldn't have grown that big.
Or their inner working is better than this article implies...
Before I purchased eclipse glasses from Amazon, I first checked with NASA for approved brands, purchased an approved brand, and have not received a recall email from Amazon.
The fact is that we don't know what happened at Amazon, whether they commingled inventory or incorrectly included legitimate suppliers in the recall or if there were real issues with the products provided by the supplier in the article.
It's easy to make fakes that look exactly like the real thing. So a printed ISO code or brand name is only sufficient if the supply chain is secure.
And unfortunately, there have been plenty of stories lately about seeming lax stock management at Amazon that makes it hard to know exactly what you're going to get.
I ordered a variety of different products and so I can see which were recalled and which were not. Based on that sample my guess is that they recalled anything with the text "solar eclipse" in the description that they could not conclusively prove complied with the relevant human-eye exposure standards which include manufacturing, documentation and tractability requirements. This would have caught : truly unsafe product; safe product that lacked the necessary paper trail; safe product that wasn't manufactured in the approved facility; product that was never marketed for human eye protection; compliant product that couldn't be separated from the above categories due to Amazon inventory commingling.
Does this have to do with Amazon's practice of commingling goods from various sources together? I imagine in some warehouse, a big box of Panjwani's legit goods all mixed together with some not-so-good-goods.
After a quick search I found this: https://www.amazon.com/gp/help/customer/display.html?nodeId=...
Even though inventory tracked using the manufacturer barcode is commingled within the network, the source of the inventory is tracked by our fulfillment systems and is taken into consideration if inventory problems arise.
Given the article, it seems they're not completely sure what was sent where. It would seem that using the manufacturer barcodes in Amazon's network opens you up to an unexpected risk.
https://www.theverge.com/2016/10/20/13343682/fake-apple-char...
edit: dug out that discussion https://news.ycombinator.com/item?id=13924546
but there are plenty similar.
Maybe legit sellers that aren't "fulfilled by Amazon" are safer because they ship it themselves?
Anecdotally, a friend of mine runs a company that produces a unique fitness product, never opted into any kind of co-mingling as far as I know, as they are the only supplier in the world - and suddenly found themselves with comingled fake stock.
Secondly there is Fulfilled By Amazon (FBA) this is when you sell the products and Amazon takes a commission and all the fulfillment fees to store and ship the product for you. In this case the seller has MUCH MUCH more control over every aspect of the listing. They can choose to have the ASIN generated by the UPC which can result in the same problem as above OR they can choose to have the ASIN generated by a number and barcode that is unique to the particular seller. This is called a FNSKU. Even if you know the FNSKU number which would be on a barcode on the product, ONLY the particular seller can create /ship product to Amazon using it. So Only the seller can variate listing or sell the product.
And thirdly you can do seller fulfillment which works list the last option in terms of listing, just with your own warehousing and fulfillment.
In fact I don't buy anything from Amazon anymore...
Safeway delivers
"The customer purchased a counterfeit item!"
Actually, no. The customer purchased an authentic item but Amazon shipped the customer a counterfeit item. Guess whose responsibility that is?
I could see Amazon having enough volume of the items they sell directly that they have less need to do this commingling, and of course they have some incentive to preserve their own image.
I purchased my glasses off the website in the comments directly below bc this is one thing I did not trust Amazon on.
Also, I'll play devil's advocate, but this is one area where eBay actually wins over Amazon as each listing is tied to 1 particular seller and viewing seller history on eBay is rather easy compared to Amazon.
It would be nice to know from a listing if a product is eligible for commingling and whether the item I'm buying is commingled or stickered. I would pay more to not purchase commingled items from Amazon.
I do feel sorry for the legit sellers bc they are going to lose ALOT of money, many through no fault of their own. I haven't been on my private groups in a while but I'm sure I "know" a few of the sellers.
Their price advantage has eroded anyways. I don't see any advantage to buying from them relative to straight from the manufacturer most of the time.
Amazon has done a great job squeezing shipping costs and margins. I doubt I pay more than 5% more on anything but I know I'm not getting any fakes
The article only talks about the sun appearing too bright through counterfeit glasses, but the real hazard is a pair of glasses that blocks out enough visible light to allow your pupils to dilate, letting in plenty of the UV they don't block.
There was never any guarantee that the invisible hand would fix badness overnight, merely that it will nudge them in the right direction. Which it does.
I checked the Thousand Oaks Optical site and they have a list of legitimate resellers of their products, and the Amazon seller I used is listed. I'm surprised Amazon didn't do the same basic checks before e-mailing me.
When I was searching for more information after receiving the e-mail, I also found someone on an astronomy forum[1] who is being refunded for a telescope that appears to retail for around $1199.
[1] https://www.cloudynights.com/topic/587658-amazon-eclipse-gla...
Everything else I'd rather buy from the manufacturer (and pay the full, unsubsidised shipping cost -- not Amazon Prime) or a reputable distributor (digi-key/mouser for electronics, CS Hyde for films/tapes, etc). The prospect of having my eyes fried because of counterfeit PPE is kinda horrifying.
If it was "fulfilled by Amazon", it doesn't matter what seller you chose, you could have been sent a counterfeit item from another seller.
Sellers using fulfillment-by-Amazon send their stock to Amazon's warehouse, where it gets thrown in the same bin as all the other stock of that item from everyone else selling it. When it gets pulled to ship to you, there's no guarantee you get one that came from the authorized seller, versus a counterfeit someone else sent in with the same SKU.
Sellers can opt-out of commingling inventory at extra cost but most don't. Given you got a proactive refund, that seller probably has commingled inventory with everyone else, and Amazon is worried they sent you a fake that'll get someone injured and cause them liability.
* Collect positive reviews on a cheap article.
* Change the product, but not the article ID. The new article then has the reviews of the old one.
* Finally, they lock the reviews by setting the article to "not released yet", even though the product is for sale.
That way, you get positive reviews for a shitty product and customers can't add negative reviews.
Amazon don't do anything about this, even though it's clearly deceptive and, at least here, against the law.
eg, there are specialized climbing harnesses on Amazon which confuse the CE EN standard and the concept of notified bodies. (Which certify conformity.) Leads to hilarity like a climbing harness claiming conformity with the standards for intubation tubes.
Or, climbing equipment which is mislabeled as to its country of origin, with basic specs like dimensions being inaccurate.
The sellers just don't care, and Amazon doesn't care enough to stop them. It's barely one step above ebay for a lot of items.
Is it, though? At least with eBay I know who the product I ordered came from and whom to blame if something goes wrong. If I'm ordering from the manufacturer's official account on eBay I know I'm not getting sent a cheap Chinese knock-off by some other random eBay seller.
With Amazon I apparently don't have that luxury.
Amazon is, for me, full of bafflement pricing.
Trying to work out what I need to buy to get free shipping becomes impossible because of the Prime Only deals, the Add On items, the difference in shipping between books only or other stuff.
Now I just buy all books from Wordery and everything else from eBay.

Fairly poor choice of words..
But this is a piece of safety equipment with a single function, and people only buy it to use it in one way, which will cause direct and immediate harm if the product fails. How can someone live with themselves after doing this?
By being able to feed their family and keep shelter over their heads.
At least that's the only charitable explanation I can think for the absolutely shocking lack of respect for human life that comes out of China (see fake food, gutter oil, electrical safety, construction scandals etc etc)
People like my ex's dad. Not involved with this in particular, but lots of fake/knockoff/cheap Chinese shit. Dude is rich as fuck. Rich enough to have bought her a $750k house with cash a few years ago, like it was nothing. Don't know if anything he was involved with ever actually harmed anybody, but from what I've heard he'd have no qualms about it. I'm sure whoever is responsible for this is similar. No rules in China if you're fucking over foreigners. At least none that you can't just bribe your way out of.

("It's not real Communism." But it's a real outcome of the attempt to create Communism, so it counts just fine.)
The thing is, if you want safety, what you want is a separation between the manufacturer and the regulator. In Communism, the manufacturer and the regulator are de facto the same entity. Communism lacks any entity that is capable of coming out and saying independently that there's a problem. If you've ever complained about "regulatory capture", you've just explained why Communism is non-functional; Communism institutionalizes 100% total regulatory capture from day one and holds it up as an ideal.
The seller confessed to the fraud, but was utterly unrepentant.
I'm trying to have the same conversation with "Microsoft Support" callers trying to install ransomware in my computer. Not much luck getting answers out of that crowd, but no pangs of conscience either.
There is a part two as well.
Or they did receive an email and it went into their spam/junk folder. In a situation like this it might be better to email everyone if only to say your glasses are safe. Although that would open them to legal liability if they're wrong.
Hopefully this was during hazy sunsets. Or maybe you just have mega-strong pupils that can contract more than normal and that's why you're not blind.
> Is the danger that an eclipse encourages you to stare at the sun without encountering any pain?
Exactly. Human eyes aren't very good at handling ultra-high-dynamic-range scenes. During an eclipse, your surroundings are somewhere between twilight and night-time in brightness, so your pupils dilate. The small un-covered sliver of sun is still as bright as it is during the day, and can damage your eyes without triggering a painful 'too-bright' response. It's somewhat similar to the danger posed by a laser.
But there are documented cases of eye damage, so the danger is real.
https://www.washingtonpost.com/news/capital-weather-gang/wp/...
The optometrist I consulted the day after the eclipse said that there didn't appear to be significant permanent damage to my eye, but the subsequent six months of the afterimage, and not being sure whether or not it would last my whole life, were certainly no fun. Overall, I feel like I got very lucky, and I wouldn't have been surprised if the afterimage had lasted for decades rather than months. Maybe it would have if I had continued looking for just a few more seconds!
My impression is that the risk of different kinds of damage is complicated, but there are several things that can go very wrong. One is that the sun during an eclipse is much more interesting than usual, so it's so much more tempting to look longer than momentarily; another is the UV exposure that people have mentioned (where there may still be enough UV to cause damage even at times when the visible light is weak enough not to cause significant discomfort). UV is a big factor that means that we shouldn't trust our intuition about whether something may harm our eyes. In industrial settings, too, people sometimes get significant eye injuries because they're staring at UV (or IR) sources that don't subjectively feel dangerous or painful.
(Edit: taneq in this thread also mentions a problem about dynamic range where your pupillary contraction may not be enough to protect you.)
While permanent damage might not happen quite as quickly as some people may have been led to believe, and some risks may be slightly exaggerated in certain accounts, there's just no reason to take the risk of not having proper eye protection, especially when you can't really judge from the level of discomfort or lack of discomfort whether damage may be happening. As far as I know, every eclipse leads to emergency follow-up optometrist visits, and I can testify that it's no fun to be the patient in one of those visits waiting to hear the news about whether the aftereffects are likely to be permanent.
When it's not, you can't. But it may not appear "as bright" when it's partially eclipsed, it may be "easier" to stare at it, without reflexes kicking in to stop it, and do permanent damage to your eyes.
It's likely that some of the afterimage is still there but your brain has been rewired to eliminate it.
I haven't gotten it from the sun, but I got a minor case of it from welding with the incorrect lenses (it may seem fine to use gas welding goggles for MIG welding, but it's really not). It's really not pleasant, your eyes feel all scratchy and too large for their sockets.
I've had hints of that from welding when using a proper mask, but inadvertently not wearing a dark enough shirt (worst case is a white t-shirt - can bounce the UV up under the mask; it's not as bad as "arc eye", but can still be uncomfortable afterward).
Other welding safety lessons:
1. Be very careful welding on zinc-coatings (galvanized steel); have plenty of ventilation, and don't inhale any of the fumes (a fan to blow the fumes away can help). You can get zinc-poisoning, which feels like a very bad flu-like symptoms. I'm sure it can be fatal, but mostly you'll feel really terrible afterward, and there's no cure except to wait it out. Better - remove the galvanization (grinding or with pool acid), or use a respirator under your mask (specifically one rated for it - there's a particular one 3M makes that if you research this topic, people recommend).
2. Less known: Never weld on steel that has been cleaned using chlorine-based solvents (like certain kinds of brake cleaner). There's a tale out there from a guy who did it, and lived to tell about it. Basically, the intense heat creates a change in the chemical to form phosgene gas; even a small amount can kill you. This poor soul managed to live, but not without some major after-effects that will cause him trouble the rest of his life:
http://www.brewracingframes.com/safety-alert-brake-cleaner--...
Note that not all brake cleaners have chlorine (they are banned in California, for example), but this is one of those things that if you've never heard of it, but you find yourself welding (especially if you also do your own brake fluid changes or brake jobs, or other auto work) - and you clean your parts (hey, let's use brake cleaner - that'll do it!) - you wouldn't think there'd be a problem - until it's much too late.
Get the word out on this last one, too - not many people know about it (most welders know about welding on galvanized steel).
> In a study after an eclipse in Turkey in 1976, around 10%of [sic] those with damage had permanent visual loss to the extent that they were not able to read a car number plate at 25 yards (23 metres) with the affected eye or eyes.[0]
IIRC, an eclipse is particularly dangerous because the lack of light doesn't trigger your pupils to constrict as much or a "too-bright" response to look away, but the visible portion is still sufficient to cause damage.
And there was so much bright light that you really couldn't look at it for very long without involuntarily looking away or closing your eyes. But of course if you kept looking at the sun no matter how much it hurt, you would damage your eyes.
In a partial eclipse, most of the sun is covered, and there is a lot less light reaching your eyes. So they don't stop down as much as they would for a normal full sun.
However, that fraction of the sun that is visible is just as bright as before! With such an interesting sight to look at, you will be much more tempted to stare. And with your pupils wide open, there is even more sunlight hitting that small area of your retina than there would have been in normal conditions.
Now if you are fortunate enough to experience the total eclipse, that is another matter entirely. It is perfectly safe to look at the solar corona during totality, even with binoculars! The corona is only about as bright as a full moon. The sun itself is completely blocked by the moon.
I viewed the 1979 total eclipse with binoculars, and when totality ended and the diamond ring and Baily's beads started to appear, I lingered a few seconds longer than I should have, and still no harm was done. I didn't suffer any temporary or permanent vision damage, even viewing those through the binoculars.
But visible light is not the only frequency. Sunlight also contains UV and IR wavelengths. The human eye does not have pain receptors that respond to these frequencies.
The end result is that during an eclipse it becomes more likely that a person will fries their eyes due to the presence of UV and IR wavelengths.

Just bought 2. 30 dollars (5 each, 20 dollars for fast shipping). Might not even need them as we have welding helmets, but I don't want to screw around concerning my eyes. Accidently got myself with a camera flash once, that was more than enough.
The question is what else are Amazon willing to do with that information, which turns out to be very little or nothing because as soon as Amazon gets humans involved in the transaction making actual decisions, their costs shoot up.
They don't, though. All the same-SKU items go into a big box at the warehouse. When you order from a particular seller, they pick one out of that box and send it to you. There's a good chance the specific one they picked out didn't come from that seller's inventory, but another's.

https://www.space.com/37698-solar-eclipse-glasses-safety-che...
But another page from the AAS seems to say you only get a negative result: if you can see anything other than a very bright light through the glasses, they're unsafe. But that doesn't imply the inverse, that if you can't, they're safe, because of UV protection. https://eclipse.aas.org/eye-safety/iso-certification
Can anyone confirm if I've understood that correctly?
That's a bit rich, what with the 2nd hand camera lens scam the other day and all.
It sucks because I recently picked up an amzn gift card from a change conversion machine (my bank now requires you roll your change yourself and I discovered those machines are fee-free if you use them for a giftcard), but I've fewer and fewer needs from Amzn now.
Use a simple lens, or even a pinhole, to project the image onto another surface and view it that way.
Here's a link to it's construction.
https://www.livescience.com/33906-solar-eclipse-viewer.html
I'd say the box the glasses come in from Amazon is probably more useful than the glasses in many cases. :)
Just to add one nuance, this is only needed for the partial eclipse. If you are viewing the total eclipse, use the pinhole projector for the partial phases. But during totality only, it is perfectly safe to view the solar corona with the naked eye, even with binoculars.
I went into more detail elsewhere in this thread; search the page for my username for more info.
The damage is usually reversible.. loss of vision returns usually within 12 months.
To answer your question, though, we need to distinguish between a partial eclipse and a total eclipse. You had best use eye protection for a partial eclipse, or even better, use a pinhole projector as I described elsewhere in this thread. (Search the page for my username.)
But a total eclipse is perfectly safe to view with the naked eye, and even with binoculars! You could use a telescope, but binoculars give you a better field of view. Either way, you're not looking at the sun any more, you're looking at the solar corona.
During totality, the sun is completely blocked by the moon itself. This is a much more substantial filter than anything you could ever buy on Amazon.
But one must be careful. As soon as the moon stops blocking the sun, there are sun rays concentrated in a tiny point. Like looking at the point of a powerful laser, it doesn't feel as powerful as it actually is. Esp. regarding invisible wavelengths.
If you are traveling to (or live in) the zone of totality, don't bother viewing the partial eclipse at all. It's not what you are there for. You are there to experience the total eclipse in all its glory, and you can't use eclipse glasses for that.
Your best viewing tool for the total eclipse is your own eyes and a good pair of binoculars. Yes, plain, unfiltered binoculars. During totality you can look directly at the solar corona. Not only do you not need eye protection, but you'll miss the whole thing if you use any kind of filter.
This is true only during totality, of course.
I recommend doing what hundreds of us did on an Oregon hillside in 1979. During the first partial phase, we put on sunglasses (just ordinary sunglasses) and looked away from the sun. The purpose of this was to get our eyes a bit dark-acclimated, so when it went total we would have an even better view.
By looking away from the sun, you also have a chance of seeing the other interesting effects on the ground: the wavy ripply patterns that appear just before totality, and the shadow of the moon as it rushes toward you at thousands of miles per hour!
As soon as the eclipse became total, people started yelling "totality!" and we took off our sunglasses, turned around, picked up our binoculars, and enjoyed the awesome experience of seeing the solar corona.
The only danger here is that you have to stop looking as soon as the first bit of the Diamond Ring or Baily's Beads appear. Then you're back into the partial eclipse and must use eye protection.
But at that point, most of us just cheered and got ready to go home. After totality, the partial eclipse is not much to get excited about.
If you're not in the zone of totality, then of course you must not look directly at the sun at any time. But if you don't have quality eclipse glasses, you still have some other good options.
One is a piece of #14 arc welder's glass. Another that you can improvise on the spot is a pinhole projector. There are various ways you can make one; at the simplest it can just be two pieces of paper, one that you punch a small hole in with a pin, and the other on the ground or a wall. Hold the paper with the hole so that the sunlight goes through it onto the other. You will get a nice image of the partially eclipsed sun projected onto the other paper.
A pinhole projector is the safest way to view the partial eclipse: you are never looking directly at the sun at all, only its projection.
There are numerous plans for building slightly more elaborate pinhole projectors. This page has some good tips:
http://www.skyandtelescope.com/astronomy-news/how-to-look-at...
Or search for "solar eclipse pinhole projector" to find more.
There is a lot of misinformation going around about eclipse viewing and eye safety. Everything above is true and correct to the best of my knowledge, speaking both from personal experience and extensive research. And I've tried to make very clear the difference between the partial and total eclipse. Of course, if I made a mistake or left anything unclear, please let me know!
There are two main dangers regarding eye safety. One is that someone may view the partial eclipse without proper eye protection and will destroy their vision. This has happened many times, and it is a real tragedy.
The other danger, albeit of a lesser sort, is that many people who travel to the total eclipse zone will mistakenly believe that they need some kind of eye protection during totality. As a result, they will completely miss the awesome, life-changing event they went to so much trouble to see.
This doesn't mean the shape can't also be copied perfectly though, so I'm not sure if it's helpful or just doing even more harm.
When I was selling inventory on Amazon, I actually paid the extra cash to have my inventory placed in a separate location so that I didn't have to deal with other seller's stock/quality issues. It was worth the additional cost (from my point of view) and it worked quite well in ensuring that Amazon's customers who sourced from my stock got the correct product and that I didn't have to deal with angry customers or unexplained returns.
There's a map of libraries on their website:

If yours is on that list, you should be pretty safe, I think.
You definitely do not want to test this on the sun.
I got mine directly from one of the NASA-approved suppliers, precisely because I don't trust Amazon anymore. Had to order a small batch, even though I only needed a few: I figured not going blind is worth ~$30.
Anyway, my e-mail is [HN account name] at x0.ms.
Are all the harmful wavelengths visible? What you don't see can hurt you (for instance, see the table at https://en.wikipedia.org/wiki/Laser_safety#Damage_mechanisms), and depending on the material it could filter some wavelengths but let other wavelengths pass. Testing just with visible light is not enough.
E1: I'll probably end up getting new ones; I guess you're right.
E2: Because everyone cares about my saga, of course, the seller appears to have sold blatantly fraudulent ones as well. Apparently lowes has certified ones, so I'm going to pop in there tomorrow.
E3: in classic "pay attention to me" style, but also in the hopes of helping someone else out: https://www.eclipseglasses.com/pages/safety my glasses look like the counterfeit version listed on the mfg website.
It's to the point where I don't bother checking Amazon for a lot of things because I know it will be too hard to find a legit seller.
The walmart i know still has them for $1.
It is not too late ever for a company to admit they made a mistake. Look at the catholic church
My bad
That's an odd way for Amazon to put it. Presumably not injuring your customers is priority number one in most businesses?
Can I take like 5 second glances?
Is there some minimum rest period between them?
(I ordered glasses but will assume they are fake).
Don't do what you suggest. Seriously.
On further research looks like something about your eye having a specific point to focus on which gets damaged immediately.
Thanks.
It seems opaque, but it is transparent enough to see the sun
The mylar composite used in floppy disks seems opaque... to visible light. 54% of the Sun's energy output is in other wavelengths. There is no certification that a floppy disk cookie will block those. Plus it has a big hole in the middle, danger of inadvertent viewing.
This is like the argument I have with other photographers every eclipse when they try to use their 'super-dark' neutral-density filters. Sure they block ten stops of light, but the IR and UV just sails on through.
Unless it's designed and certifed as a Solar viewing material just don't even contemplate it. You're better watching the eclipse on TV in that case.
People have been using dark pieces of photographic film to see eclipses since ever. I wonder if there has been studies on its UV transmissibility
Thought you're right about the super-dark film and I don't think those are dark enough even on the visible range
Though I do agree if you want to stare at it directly your best choice is to get solar viewing glasses (preferably not a fake one)
This page has some tests: astronexus.com/gatfaq/solar-filters besides poor optical quality floppy disks allow wavelenghts > 800nm to pass (this is IR range)
A good suggestion that seems easy to obtain: welder's glass
Fully exposed and developed black and white film is safe, color negative film, however, is totally unsafe, regardless of how dark it might seem. The film has to contain real silver particles, not color dyes.
Beware of monochromatic film that looks black and white but it’s really a color negative film developed using C41 process. It has to be real black and white film.

>One of the most widely available filters for safe solar viewing is a number 14 welder's glass, available through welding supply outlets.
And both colour fim and non-silver B&W film are listed by them among the unsafe:
>Unsafe filters include color film, some non-silver black and white film, medical x-ray films with images on them, smoked glass, photographic neutral density filters and polarizing filters.
https://eclipse.gsfc.nasa.gov/SEhelp/safety2.html
> Many experienced solar observers use one or two layers of black-and-white film that has been fully exposed to light and developed to maximum density. The metallic silver contained in the film emulsion is the protective filter. Some of the newer black and white films use dyes instead of silver and these are unsafe. Black-and-white negatives with images on it (e.g., medical x-rays) are also not suitable. More recently, solar observers have used floppy disks and compact disks (both CDs and CD-ROMs) as protective filters by covering the central openings and looking through the disk media. However, the optical quality of the solar image formed by a floppy disk or CD is relatively poor compared to mylar or welder's glass. Some CDs are made with very thin aluminum coatings which are not safe - if you can see through the CD in normal room lighting, don't use it!! No filter should be used with an optical device (e.g. binoculars, telescope, camera) unless it has been specifically designed for that purpose and is mounted at the front end (i.e., end towards the Sun). Some sources of solar filters are listed in the following section.
> Unsafe filters include all color film, black-and-white film that contains no silver, photographic negatives with images on them (x-rays and snapshots), smoked glass, sunglasses (single or multiple pairs), photographic neutral density filters and polarizing filters.
This second NASA author seems to believe that floppy disk media (with the hole covered) may actually be safe for eclipse viewing, just not very effective.
