You could also use #14 welding goggles. I guess NASA faked those, as well. Also, NASA doesn't make the glasses. They just say don't be stupid and stare at the sun, which apparently is something flat Earthers need reminded of.

As for what makes the solar eclipse different, nothing. It is still absolutely the same unless you are in totality, but that only lasts a couple minutes. The Sun is still every bit as bright in the parts that aren't blocked by the moon and will still damage your eyes. It was about 80% covered where I was and while it was a bit darker out, the sun was still overpowering to glance at.

I agree mostly with what you're saying.

NASA doesn't make special glasses, however, if you're going to be staring at the sun for that long of a time period there has to be protective eyewear or else someone is getting sued.
