NASHVILLE, Tenn. (CLARKSVILLENOW) – NASA has issued a safety alert about “unsafe eclipse glasses being distributed by unscrupulous companies.”
The agency is recommending consumers only use 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.
