Eclipse Glasses
Apr 3, 2024 07:34:44 #
If you plan to look at the solar eclipse next week, you should use good eclipse glasses. How do you know what's good? You don't. The "good" ones will have ISO 12312-2 printed on them. Don't you think the counterfeiters would be able to print that number on their phony glasses?
[i]"The best way of knowing your eclipse glasses are safe is to get them from a reputable source. Check for the international safety standard-certification number ISO 12312-2, which will be on the glasses' frame. If you aren't sure, try wearing the glasses indoors. You should not be able to see anything except very bright lights, and even they will appear faint."[/]

Welder's glass is also good, depending.
"Looking directly at the sun can cause severe vision impairment and partial blindness, which is why people usually avoid doing so. However, during a solar eclipse, viewing the sun can be a desirable experience. Unfortunately, solar eclipse glasses can quickly sell out when an eclipse occurs, leaving people to search for alternatives such as welding glasses. It is noteworthy that most welding glasses are not suitable for looking at the sun, and using them can be risky for your eyesight. Only welding glasses with the darkest shade level of 14 can protect your eyes properly, but these are uncommon and may not be available in many hardware stores."
By the way, eclipse glasses are not necessary for viewing a lunar eclipse. 😁

I don't expect to be able to see much of it anyway, path is pretty far west and north of where I'll be.

While I understand the desire for safe viewing, I always wonder where Galileo bought his mylar glasses...

My eye doctor was giving them away free to patients. I had been looking on line but I also concluded that you couldn't trust the maker. It might say ISO 12312 2 but you don't know if you can trust that.

Yeah, you have only one chance to go blind.

We have a reservation for a place in the path of totality, but right now, the forecast for next Monday in Texas is... 90% cloud cover and rain.
