  > Couldn't see light bulbs or anything else but the sun. Are all the harmful wavelengths visible? What you don't see can hurt you (for instance, see the table at https://en.wikipedia.org/wiki/Laser_safety#Damage_mechanisms https://en.wikipedia.org/wiki/Laser_safety#Damage_mechanisms), and depending on the material it could filter some wavelengths but let other wavelengths pass. Testing just with visible light is not enough.

    That's not really something I could test readily at home. Additionally, the light bulb test is what the local news was saying is a good quick and dirty test to check for counterfeits. I obviously can't certify them. https://eclipse.aas.org/eye-safety/iso-certification https://eclipse.aas.org/eye-safety/iso-certification E1: I'll probably end up getting new ones; I guess you're right. E2: Because everyone cares about my saga, of course, the seller appears to have sold blatantly fraudulent ones as well. Apparently lowes has certified ones, so I'm going to pop in there tomorrow. E3: in classic "pay attention to me" style, but also in the hopes of helping someone else out: https://www.eclipseglasses.com/pages/safety https://www.eclipseglasses.com/pages/safety my glasses look like the counterfeit version listed on the mfg website.
