Description: These is a tutorial which can tell you how to avoid buying fake solar eclipse glasses within two easy steps.
We are less than two weeks away from the great American total solar eclipse, so today we are going to be talking about how to make sure that you are not buying fraudulent or fake solar eclipse glasses.
The things you are going to need to test the eclipse glasses are two items, the glasses you purchased and some right light source, like a flashlight. The first thing is that you can see a confirming to the standard called ISO, which stands for the International Organization for Standards. As you can see, my glass has the brand, the ISO sign and all the standards.
The step two is to get your light source. All you need to do is to hold your lens on eclipse glasses up to the light source. You can see there is a light behind it, but there’s nothing coming through. It can protect your eyes from all the rays that may be bad to your eyes.
