Medical king Solar Eclipse Glasses Plastic AAS Approved 2024 (2/8/18/48 Pack) CE, ISO Certified Safe for Direct Sun Viewing

After reading some of the negative reviews, I was wondering if I made a mistake ordering these. This turned out not to be the case, at least for the pair of Eclipse Glasses I received when I tried them! Yes, they are very dark, and you can't generally see anything in normal lighting when wearing them. But this is intentional! They are not sunglasses, they provide much more brightness reduction so that you can look directly at the sun. I went outside and looked directly at the sun wearing them, and its disk was clearly visible. Not bright, but easy to see. I am nearsighted and normally wear eyeglasses for distance. The Eclipse Glasses fit over my glasses fine, but I have fairly small aviator-type wire frames. I suspect that if you wear the larger plastic-framed eyeglasses that seem to be popular these days, the Eclipse Glasses may not fit over them as well. I found the plastic frames to be perfectly adequate and comfortable, lots better than the light, thin cardboard frames that come with some eclipse glasses. Yes, they are inexpensive and not up to the quality of normal eyeglasses, but they're perfectly fine for their purpose, in my opinion. In addition, an information sheet including an official-looking "certificate of conformity" to "EN ISO 12312-2-2015" is provided in the box. That's a least somewhat reassuring. The glasses are dark enough that I expect they provide a good level of safety, especially if you comply with the instructions printed on the box. Another point is that during Totality, these would be too dark to see much of anything, they are really useful for the time when the eclipse is transitioning into and out of totality with any of the sun at all exposed. But my understanding is that when the moon is completely covering the sun, you can look at it without eye protection. I personally would not stare at it, but take brief views and photograph it.

It occurred to me, after trying to look directly at the unobstructed sun, that perhaps these glasses passed the American Astronomical Society certification because **they let no light pass at all.** I could not see anything through the glasses--not the eclipse, not the full bright sun. Granted, there was a bit of haze, but two women next to me were looking through approved visors with cardboard frames and they could see the eclipse just fine. They were very generous to let me use their glasses and then I could finally see the thing.My concern is that this product could have made someone frustrated and then try peeking at the sun directly because the "safe" glasses were completely obstructing the view. Just because the glasses are made of apparently higher quality materials doesn't mean that they are actually useful, or better, than much cheaper pairs of disposable sunglasses.It even occurred to me that, perhaps, I was having the same problem as a person standing in a lighted room trying to see out a window into the night: light from behind me was reflecting off of the interiors of the lenses and preventing me from seeing anything. This may have been the case, but even with my hands to try and form covers around my eyes and temples I could not block out enough of the excess light (more come in through the nose piece) to let the image of the eclipse shine through, if it was going to do so at all.Terrible mistake I made here, but given that the next eclipse won't come along for many years I doubt it will be useful to anyone but Amazon who might know what this company will morph into next.

I was asked to review these before I even got them so I gave them a one star because I didn't receive them on time. Having said that these are just what I wanted. The last solar eclipse I purchase a bunch of the paper glasses to view the solar eclipse and they were fine for something disposable to give to my students. This time I wanted something sturdier. These are perfect. They are not good for anything else, they are not regular dark mirrored sunglasses. When you put them on everything looks completely black. Go out to view the sun put them on and look at the sun and you will see nothing else, just the sun. You can't see your friends or where you are walking so be careful. Enjoy the eclipse safely.

I did test these out by looking at the sun through them and no signs of eye damage. I even had a regular eye exam a month later and no issues.For those who complain about not seeing anything when these are on, that is a GOOD sign. You don't want to be able to see anything other than the sun or a very bright light, otherwise the glasses are not safe to see the sun directly.

I'm surprised by all the bad reviews. It seems there might be a production issue and lack of quality control with Medical King, but they are not a scam. If you are lucky enough to not get one of the defects, these do work fine. They are supposed to be opaque, except for when viewing the sun. The sun is the ONLY thing you should be able to see with these glasses. I used them for viewing the eclipse on April 8. I will hang on to them for future eclipses. I was able to see the eclipse just fine. I was not in totality, so I had to wear them the entire time and my eyes are just fine. They do not have the ISO certification stamped on the glasses, but they do provide the certificate in the box. Also Medical King/Solar King is on the American Astronomical Society's list of safe manufacturers. It is unfortunate that there are so many defects that went out. I would be very upset as well, and hopefully everyone was able to get their money back. But for me, they worked great, I'm glad to have them.
