(St. Louis) -KTRS
Scam artists are taking advantage of the August 21st phenomenon as demand for protective glasses is peaking.
The American Astronomical Society has updated safety advice in light of what they term– alarming reports” of unsafe “eclipse viewers” popping up online.
The organization advises buyers to be skeptical even if the glasses are stamped with a seal of the International Organization for Standardization–or ISO- stamp.
The astronomical society says- quote- “It now appears that some companies are printing the ISO logo and certification label on fake eclipse glasses and handheld solar viewers made with materials that do not block enough [light],”-end quote.
To test your eclipse glasses the AAS says put them on and “you shouldn’t be able to see anything…except the sun itself.”
Not the lights in your house, not headlights on the street. Nothing but the sun.
If you can see anything else through the film, toss the glasses and find a pair that works.
