hi! my school district in CT is working with AWB to send back our glasses. they did mention to us that the project won't work unless they reach their fundraising goal of $7,500 (they're only at about $1,500). maybe you could also encourage people to donate? if everyone sending back glasses gave just $1... :)
What is your source for the fact that they don’t expire if in good condition? One of ours actually has an expiration date in 2024 printed on it, which obviously seems wasteful and unnecessary
NASA! From their website: “If your eclipse glasses or viewers are compliant with the ISO 12312-2 safety standard, you may look at the uneclipsed or partially eclipsed Sun through them for as long as you wish. Furthermore, if the filters aren't scratched, punctured, or torn, you may reuse them indefinitely. Some glasses/viewers are printed with warnings stating that you shouldn't look through them for more than 3 minutes at a time and that you should discard them if they are more than 3 years old. Such warnings are outdated and do not apply to eclipse viewers compliant with the ISO 12312-2 standard adopted in 2015.”
This is soooo good to know! I was curious what could be done with them. Also participating in #Write_On so this checks the box of today's letter as well :)
Lots still have printed expiries on them, but according to NASA, if they’re compliant with the ISO 12312-2 safety standard adopted in 2015, they can last forever if not damaged!
Great resource! Thanks, Erin.

Thank you! One of the blessings of IG is seeing local businesses collect them for reuse
I thought eclipse glasses expired! Thanks for this resource! Even if I saved them for 20 years we have extras.
