eli5: Why did eclipse glasses say to only look at eclipse for 3 minutes at most, intermittently over a few hours.

eli5:

I only saw this warning after I had looked through them for around 3 minutes (give or take a minute maybe, I’m not sure)

Now I’m anxious about whether they were even safe to use or not.

On NASA’s own website they say compliant glasses are printed with this warning, but that they have changed the guidelines and that as long as it’s ISO 12312-2 compliant, you can look at them for as long as you want. Even if they have this warning. I believe new glasses still put this warning anyways just to save themselves from legal action in the case of misuse.
