Solar Eclipse Glasses: Why Everyone Needs Them and Best Places to Buy Them

As people across the country prepare to watch what is being called "The Great American Solar Eclipse," experts warn that viewing the phenomenon can be dangerous without the appropriate protection.

On Aug. 21, a total solar eclipse, where the moon completely covers the sun, will be visible in the U.S. from Oregon to South Carolina. It's the first total solar eclipse that can be seen coast to coast and only from the continental U.S. since the country's founding.
