NASA warns of unsafe eclipse glasses

NASHVILLE, Tenn. (WKRN) – - NASA has issued a warning letting people know that 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

- 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.
