Looking directly at the sun is unsafe except during the brief total phase of a solar eclipse ("totality"), when the moon entirely blocks the sun's bright face, which will happen only within the narrow path of totality (https://go.nasa.gov/2pC0lhe (link is external)). Eclipse glass The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as "eclipse glasses" (example shown at left) or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun; they transmit thousands of times too much sunlight. Refer to the American Astronomical Society (AAS) Reputable Vendors of Solar Filters & Viewers (link is external) page for a list of manufacturers and authorized dealers of eclipse glasses and handheld solar viewers verified to be compliant with the ISO 12312-2 international safety standard for such products.

I am reminded of Jennifer Lawrence in "American Hustle". The movie takes place in the 70s. She plays a rather dim person. Her husband is gifted a microwave oven, as part of some graft and corruption Thing. The directions say not to use metal utensils in it. Her response is "You can't tell ME what to do!" Somehow, I get the feeling that there are those who will not listen to sound advice because "Mama always told me not to look into the eyes of the sun. But Mama. That's where the fun is!" |

I doubt it is that to be honest. It's more likely that the average person can't tell the counterfeit glasses from the real ones. I suppose good counterfeits, will have a fake ISO number on them anyway. |

I'm surprised I haven't gotten a safety memo at work yet, given my window placement. |

I doubt it is that to be honest. It's more likely that the average person can't tell the counterfeit glasses from the real ones. I suppose good counterfeits, will have a fake ISO number on them anyway. Well, a fair number of Khyber Pass rifles have EИFIELD stamped on them… I wonder what the funniest possible typo would be. For example,
ISO 13212 provides guidance on the design of stability studies for use in gathering information to enable determination of the shelf-life of contact lens care products. But you were talking about good fakes… |

I got mine from a reputable telescope manufacturer, so I ought to be safe. |

Picked mine up at NASA itself, so I should be OK. |

NASA? what do they know about the sun? Haven't even been able to put a rover on the surface of it yet. |

That is because they haven't been able to find anyone willing to fly it there. Something about it being a one way trip. |

They should send it at night. |
