uys, don’t stare at the sun, okay? Just don’t. And if you must, please make sure you have the right pair of specialty glasses built for this.
Of all the things that my parents taught me, this was the first and truest.
I remember once asking my dad why I couldn’t look at the sun. And he said “Well, it hurts your eyes” and I tried it anyway, because I’m a jerk, and it did hurt my eyes, and he said “See?”
So to spare you that whole humiliation, just take my word for it: Don’t look at the sun.
And look, I get it, you’re excited, there’s a solar eclipse coming!
When things are hidden it just makes us want to look at them more. Like Pokémon or presidential tax returns.
But look, staring at the sun, even when it is eclipsed, can do very bad things to your eyes.
Basically staring at the sun for a long enough period of time can leave you partially blind. Even if you’re just doing it on eclipse day.
So protective eyewear is important.
Many different kinds of protective eyewear have been sold to consumers that promise safe eclipse viewing.
But not all protective eyewear is created equally.
So here's some research you can do to make sure your own pair of “eclipse glasses” are safe, before you attempt to stare at the sun (which you should never do!).
Firstly, when you look at the wording on your glasses, you should see “ISO 12312-2” or “ISO 12312-2:2015.” This signifies that the glasses are able to block the sun’s UV and IR radiation.
But, that still might not be enough to be sure your glasses are safe.
