NASHVILLE, Tenn. (WKRN) – NASA issued a warning Thursday to let people know unsafe eclipse glasses are being distributed by “unscrupulous companies.”
The space agency recommends only using eclipse glasses with ISO 12312-2 printed on them that have been printed by the four following companies: American Paper Optics, Rainbow Symphony, Thousand Oaks Optical, and TSE 17.
NASA says buying your eclipse glasses on Amazon does not ensure their safety.
“Make sure to check your eclipse glasses and viewers to verify that they have the correct ISO designation and were manufactured by one of the four companies recognized by NASA as legitimate,” the agency noted.
It’s unsafe to look at the sun for any amount of time as it can possibly be dangerous and lead to permanent damage, hence why purchasing eclipse glasses is so important. Read more from NASA’s website.
The total solar eclipse, considered a once-in-a-lifetime experience for everyone in the Middle Tennessee area, takes place in just 31 days on Aug. 21.
You should wear your glasses through the majority of the event, only taking them off when the moon completely blocks the sun.
While the eclipse begins at 11 a.m., it will reach totality around 1:28 p.m., making the sky go dark for upwards of 3 minutes, depending on where you live. When will it reach your house and how long will it last? Find the answer here.
