NASA Issues Warning About Unsafe Eclipse Viewing Glasses

Eclipse2

Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate, said it's a good idea to practice putting the glasses on with children before the eclipse.

"Only with special-purpose solar filters, such as eclipse glasses or a handheld solar viewer, you can safely look directly at the Sun", the agency said.

Glasses that are safe to use for eclipse viewing will be certified by ISO with a reference number of 12312-2 printed on the glasses. They also reccomend AstroSolar Silver/Gold lensed glasses by Baader Planetarium. It is a total solar eclipse and it is mostly viewed in America a. These should include an ISO 12312-2 designation and lenses that are less than three years old.

For starters, do not use ordinary sunglasses, irrespective of how dark they are and what UV protection they offer, to look at the eclipse directly.

NASA encourages people to follow precise instructions to follow safety procedures and alternatives to experience the eclipse without compromising one's health.

Some older solar-viewing glasses may meet previous standards for eye protection, but not the new global standard, Fienberg said.

"Always inspect your solar filter before use; if scratched or damaged, discard it".

"While NASA isn't trying to be the eclipse safety glasses 'police, ' it's our duty to inform the public about safe ways to view what should be a spectacular sky show for the entire continental United States", said Alex Young, Associate Director at NASA's Goddard Space Flight Centre in Greenbelt, Maryland. Similarly, do not look at the sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses or hand-held solar viewer - the concentrated solar rays will damage the filter and enter your eye (s), causing serious injury.

One of the most popular projects is called Eclipse MegaMovie, a partnership between Google and University of California, Berkeley.

Two other satellite tools aboard the Terra and Aqua satellites, launched in 1999 and 2002, respectively, "will provide observations of atmospheric and surface conditions at times before and after the eclipse", said NASA.
