Buyer beware: Fake solar eclipse viewing glasses for sale online
With less than two weeks until the Great American Total Solar Eclipse, some reports have surfaced about people selling fake solar eclipse glasses.
No matter where you are going to observe this solar eclipse, you are going to need eye protection.
The only exception is for those lucky enough to be in the shadow of the moon, where solar glasses can only be taken off during the few minutes of true totality. This is when the moon covers the entire sun for a few fleeting minutes.
Proper solar glass should have an ISO certification stamped on them, or have some type of written certification in the shipment. The specific ISO certification for this type of product is IS0 12312-2, meaning that they meet safety requirements.
Some people can simply stamp the ISO numbers on glasses, so its best to check out a list of approved vendors to ensure yours are in compliance.
When wearing the glasses, you should not be able to see anything but the sun. Check the glasses for any tears or holes and assist children and elderly in how to use them properly.
Keep in mind the eclipse should begin at 9:13 a.m. on Aug. 21 and will reach its peak at 10:33 a.m. It will be over by noon.
Some 70 percent of the sun will be covered by the moon at maximum eclipse.
