NASA recommends only using eclipse
glasses printed with ISO 12312-2 on them that have been manufactured
by four U.S. companies: American Paper Optics, Rainbow Symphony,
Thousand Oaks Optical, and TSE 17.
CFSB’s glasses are printed
with ISO 12312-2:2015 on the inside of the left ear and were
manufactured in Reseda, California by Rainbow Symphony, Inc.
NASA also states that individuals should discard old eclipse viewing
glasses, as they become unsafe after three years. Also, scratched or
wrinkled lenses are not safe for viewing the eclipse. Please be safe
while viewing on this upcoming special day!
