Solar Eclipse Glasses CE and ISO Certified - Safe Solar Viewing - Viewer and Filter - Eye Protection (3 Pack - Plastic Frame)

These glasses:1) do not have "ISO 12312-2" or "ISO 12312-2:2015" printed on them2) do not have the manufacturer's name or address printed on themNASA recommends that both these standards (among other) exist for glasses to be considered safe for eclipse viewing. Amazon won't let me link to the guidelines, so you will have to google "nasa solar eclipse glasses"I don't think it's worth risking my eyesight to save some money, so I ordered directly from one of the recommended manufacturers. That NASA site states, "Our partner the American Astronomical Society has verified that these five manufacturers are making eclipse glasses and handheld solar viewers that meet the ISO 12312-2 international standard for such products: American Paper Optics, Baader Planetarium (AstroSolar Silver/Gold film only), Rainbow Symphony, Thousand Oaks Optical, and TSE 17."These glasses DO have the words "Not For Use As Sun glasses" printed on them (yes, with that capitalization). Do you trust that? I don't.

I have to come to the manufacturer's defense here. NASA even said that there are MANY safe glasses that are NOT on their list. It's not really fair that they only named a FEW.However the AAS came out with new guidelines, and they DID tell YOU how to check yourself. Mine pass EVERY test.The AAS said: Viewers should not be able to see anything through them besides the sun itself, and the sun shouldn't be too bright."If you can see ordinary household lights through your eclipse glasses or handheld viewer, it's no good," AAS representatives wrote in their updated guide. "Safe solar filters produce a view of the sun that is comfortably bright (like the full moon), in focus and surrounded by black sky. If you glance at the sun through your solar filter and find it uncomfortably bright, out of focus and surrounded by a murky haze, it's [the viewer is] no good."I tested MINE this way:I can't see ANY on my house lights. Even an inch away from a 100watt bulb, it is TOTALLY black. I thought I got ripped off when I first got them because you can't see ANYTHING with them on.But then I looked at the sun and... PERFECT! It is the ONLY thing I can see with them on and it is not too bright at all. The AAS said the sun should be about as bright as the moon... If anything, I feel the sun is LESS bright than the moon with these glasses... BY A LOT. After doing the AAS test, I thought "maybe these are TOO dark!" The image was also CRYSTAL CLEAR.I looked at the FULL sun in the middle of the day for like 3 minutes with these and I didn't have ANY "spot" in my eyes as if I had looked at anything bright. I think people are over dramatizing the situation... You would know it the sun was too bright... It would not feel good.Try them out. Look at the sun and see if you see a "spot" after. If the sun seems too bright, the glasses are bad. In my case? They seem to be PERFECT!

Unfortunately, we trusted the description on Amazon, but the glasses have no markings as to certification or manufacturer. The package says they are certified and made in China. They may be safe, but there is no way to know for sure. So sorry that Amazon would allow false description. NASA seems to be the place to go to get information, and we would advise buying the glasses locally.so you can see what you are buying.

We ordered two 3 packs of glasses, and they arrived on time, as expected. The problem is that one of the pairs does not work at all. All the others worked but 1 doesn't. Since we have 6 people, we need 6 items. Now I need to return one whole package because of 1 defective pair. Quite a hassle, but we will need these before traveling.

WARNING! 1 out of 3 glasses in the set could not filter out light from a 20w LED light! It was clearly visible from 20 feet away. No way am I letting my kids (or wife or me) use these to view the eclipse.Does not appear to be a certified maker of Eclipse glasses as per NASA's websiteMade in china.Don't buy these.

I'm so excited to see the solar eclipse in August. I just put on a pair of these and went out to look at the sun. No problem! No squint required, no pain. They appear to be just what's needed.I got three pair with my purchase, black, orange and green plastic frames.

I am somewhat concerned now that these do not meet the standards of NASA for eclipse viewing. They are made in China, do not have the manufacturers name/address imprinted, The ad does indicate that it has the proper ISO reading....just not sure about them :(

Some came scratched, bent, and certification not clearly evident on glasses where it should be. Before giving these to my family, including my children, I wore them for a few seconds to look at the mid-day sun. I felt uncomfortable amounts of light hitting my eye and have had a slight blur ever since. Glasses I actually used for the eclipse did not have that problem.
