We are a little more than a week away from the total solar eclipse on April 8 and lots of people have their plans in place, including getting those glasses you'll need to actually see the eclipse.
But according to the American Astronomical Society, there are a lot of fakes out there.
So how can you tell what's real?
The orange-framed glasses at the top are counterfeit. They come with black lenses that have straight left and right edges.
Meanwhile, real eclipse glasses like the pair at the bottom have reflective lenses with curved left and right edges.
The AAS says counterfeit glasses may be hard to spot because they have text and original artwork tat makes them appear real.
To make sure you're not getting a fake pair, you can check the list of safe manufacturers and resellers on American Astronomical Society's website.
