Andrew Lund, the owner of a company which produces eclipse glasses, noted that not all counterfeit glasses were necessarily unsafe. He stated to "Quartz" that the counterfeits he tested blocked the majority of harmful light spectrum, concluding that "the IP is getting ripped off, but the good news is there are no long-term harmful effects." As one example, the Springdale Library in metropolitan Pittsburgh, Pennsylvania, accidentally passed out dozens of pairs of counterfeit eclipse glasses, but as of August 23 had not received any reports of eye damage.
