        "text": "As the August 12 total solar eclipse approaches, I wanted to share a story. In 2024 I bought a set of solar eclipse glasses and found that the Sun looked way too bright for comfort.  By chance I tried them on inside, and I could see light bulbs, ceiling fans, etc.  I was pretty sure that wasn't supposed to happen.\n\nThat sent me down a rabbit hole researching how to tell whether the eclipse glasses were safe or not. I found three simple checks that anyone can do:\n\n**1) Check the markings:** Legit eclipse glasses should have printed information indicating compliance with the ISO 12312-2 standard.  This is not a guarantee, but it shows they did their homework.\n\n**2) Try them indoors first:** You should not be able to see ordinary objects or details in the room through properly rated eclipse glasses. It's normal to see the filament from a bright incandescent bulb or a really bright LED light.\n\n**3) Check the manufacturer:** The American Astronomical Society keeps a list of vetted solar eclipse glasses makers.\n\nIf you'd like to see these checks demonstrated, I put together a short video (please forgive my jumpiness, too much caffeine):\n\n[https://youtu.be/Q8aYrD32aAM](https://youtu.be/Q8aYrD32aAM)\n\nI hope all of you lucky enough to see the upcoming total solar eclipse has a wonderful time.  The 2024 experience was amazing.",
