My daughters school supplies eclipse glasses, and when she got home she said her eyes hurt (but she’s a kinder so even just not blinking could be what’s going on) Her school gave her Frey branded eclipse glasses, probably bought from this site which no longer lists them https://www.schoolspecialty.com/ https://www.schoolspecialty.com/ They seem equal to our B&H glasses using the phone light, but it’s lacking the ISO logo (it does print the standard) nor does it have where it was made. Hopefully it’s okay, but I kind of expected schools to look for a validated distributor, and I’m not convinced this is one.
