If you’re going to watch a solar eclipse, you need to wear special glasses. There’s not anything different about the sun or its radiation during the eclipse — it’s just that our moms were right when they told us not to stare at the sun because it will hurt your eyes.
If you don’t care about watching the eclipse, you can go on with your life as you otherwise would — no glasses needed. But if you’re one of the millions of people who will be staring at the sky Aug. 21, you gotta get those shades. They filter out nearly all of the incoming light so you can actually see the moon covering up the sun without damaging your eyes.
Of course, demand breeds profit … breeds scams … breeds even more profits. And that’s what the solar eclipse is all about, right? Profits!
