If you purchased eclipse glasses via Amazon and didn't receive an email, your glasses are likely okay.
"Safety is among our highest priorities," Amazon told the Oregon-based KGW. "Out of an abundance of caution, we have proactively reached out to customers and provided refunds for eclipse glasses that may not comply with industry standards. We want customers to buy with confidence anytime they make a purchase on Amazon.com and eclipse glasses sold on Amazon.com are required to comply with the relevant ISO standard."
MASCOTKING, who has had glasses removed from Amazon, told Verge it is "submitting to NASA and Amazon" and will refund any customer who is "dissatisfied." Similar statements have come from other brands that are defending their glasses despite being pulled from Amazon.
