The ‘Great American Eclipse’ is coming — but are your glasses really safe?

Next week, people will be doing what they’ve been told for years not to do: Stare at the sun.

Let’s just hope they’re wearing the proper glasses for it — and using them at the right time. On Aug. 21, Americans — especially those in Oregon, Idaho, Wyoming, Tennessee and South Carolina — will see the sky go completely dark for a few minutes during the “Great American Eclipse.” It’s a rare occurrence. In fact, 1918 was the last time a solar eclipse was viewable on a path that crosses the entire country.

The National Aeronautics and Space Administration and the American Astronomical Society (AAS) — part of the National Science Foundation — are advising people to wear solar eclipse glasses to avoid permanently damaging their eyes.
