The US will get to see a solar eclipse on August 21 when the moon crosses between the Earth and the sun.
Here's the quickest way to tell if your solar eclipse glasses are fake
While you can't test whether the solar filters in your glasses are up to standard, you can test to see if the glasses are unsafe.
Those in the path of totality will see a total eclipse, where the moon completely blocks out the light from the sun. The rest of the country will be able to see a partial eclipse.
Viewing an eclipse (full or partial) can be a dangerous endeavor, since you shouldn't look directly at the sun. Luckily, glasses with solar filters let you see the eclipse without damaging your eyes.
But there have been concerns about scam glasses that might leave people without the proper protection.
Here's a simple way to check whether your glasses are unsafe: A safe pair of glasses won't allow any ordinary light to get through. So if you put on your pair of glasses inside, you really shouldn't be able to see anything.
