The County in partnership with other public safety agencies purchased roughly 75,000 solar eclipse glasses currently distributed by first responders, cities, Lincoln County and the Lincoln County School District. These glasses purchased through Rainbow Symphony, a verified brand, have some identifiable graphics. Common on all glasses is the County logo with “thelincolncountyfair.com” on the front/side. These glasses also have the ISO 12312-2 certification number on the inside.

Short Answer (https://eclipse.aas.org/eye-safety/iso-certification)
We used to say that you should look for evidence that they comply with the ISO 12312-2 international safety
standard for filters for direct viewing of the Sun. But now the marketplace is being flooded by counterfeit eclipse glasses that are labeled as if they’re ISO-compliant when in fact they are not. So now we suggest that you make sure you get (or got) your eclipse viewers from one of the suppliers listed on our Reputable Vendors of Solar Filters & Viewers page. (Also listed below)
