I've been duped...and I
hope you weren't too!
After reading a couple
of articles about fake eclipse glasses, I performed a simple at-home
test on the supposedly ISO certified offerings I bought on Amazon. I
placed the glasses on my face and turned toward an ordinary household
light.
From what I've read,
true eclipse glasses would have showed only total darkness in this
situation. Unfortunately, I could easily see the light through my
glasses...meaning that I could have burnt out my vision while watching
the upcoming solar eclipse.
So if you've bought
eclipse glasses, test them today. This test isn't a sure-fire way to
tell glasses are safe, but it can definitely
pull out the cheapest knockoffs like ours that aren't safe. To be 100% confident,
buy only from the approved
list of suppliers.
Good luck and hope for cloudless skies!
I don't know about mine. I haven't put them on yet because they have instructions not to wear them prior to the eclipse, but they are upstairs and I will test them.
I bought 2 sets.

I assume the second link is junk. Not sure about the first one.
I have 3 of the first one so I hope they are good!
Very frustrating not to have good specs.
Johnson City Public Library states that Lowes and Walmart are selling the eclipse glasses as well for a nominal fee. Walmart's selling them for $1.00.
Yes, the lenses need to look black when you're looking through them. It's a lot like the glass in a welder's helmet.
