If you need to be told that staring directly at the sun is dangerous, then you should probably keep that to yourself… Naturally, a few idiots out there plan to stare at the eclipse today even though they know you’re not supposed to!
Staring at the sun for too long causes a photochemical reaction in your retinas that can kill the cells. But you can’t feel it, because you don’t have pain receptors back there. And once it happens, it’s irreversible.
A second or two might not hurt you. It’s just like staring at the sun on a normal day. But if you glance three or four times, it adds up. And permanent damage can happen pretty fast, especially for young people.
A 71-year-old guy in Portland, Oregon has been speaking out about it. He stared at a partial eclipse with his right eye for about 20 seconds in high school. And he still has a pea-sized blank spot in his vision over 50 years later. So it’s really not worth the risk.
The only time you CAN look at an eclipse is during “totality.” Even if there’s just a sliver of sun showing, don’t do it. And if you bought eclipse glasses online, Google them to make sure they’re legit, because there were some bogus ones on Amazon.
Also, be careful if you’re driving during the eclipse. A lot people might try to look at it and stop paying attention to the road. They also might not turn their headlights on if it gets dark. And they might pull over on the side of the highway to check it out. So look out for people on the shoulder.
Wherever you are, you can watch the eclipse online at nasa.gov/eclipselive.
On Monday, Aug. 21, 2017, a solar eclipse will be visible across North America. Throughout the continent, the Moon will cover part – or all – of the Sun’s super-bright face for part of the day. For those within the narrow path of totality, stretching from Oregon to South Carolina, that partial eclipse will become total for a few brief moments. Make sure you’re using proper solar filters (not sunglasses) or an indirect viewing method if you plan to watch the eclipse in person. Wherever you are, you can also watch Monday’s eclipse online with us at http://www.nasa.gov/eclipselive. Starting Monday, Aug. 21, 2017 at noon ET, our show will feature views from our research aircraft, high-altitude balloons, satellites and specially modified telescopes, as well as live reports from cities across the country and the International Space Station.
