NASA reminds public to use ISO-certified eclipse glasses for safe viewing

Midland County Public Libraries have scheduled a Solar Eclipse Safe Viewing Seminar with local astronomer Daryl Lane from 5 6 p.m. August 14 at the Centennial Library, 2503 W. Loop 250 N., Midland.

McDonald's locations in OR are on NASA and the American Astronomical Society's list of certified retailers of eclipse glasses, which allow you to safely watch the solar eclipse on August 21. The SDSU Society of Physics Students will host a campus viewing session near the west entrance to the Student Union Aug. 21 and will have free eclipse glasses available at that location starting the morning of the event. The eclipse will be visible here from about noon to 3 p.m. Normal sunglasses don't provide enough protection.

If you're buying eclipse glasses, you'll also want to be sure they're not cheap knock-offs, Fienberg said.

According to, the material for safe viewing glasses is low-priced and readily available through astronomical supply houses and at their website.

The American Astronomical Society has listed manufacturers of eclipse glasses on their site, which are verified to be compliant with the ISO 12312-2 global safety standard.

The safest way to look at the sun, whether during an eclipse or not, is through specially designed solar filters. If it is scratched or damaged, throw it away.

Always supervise children using solar filters. If your glasses have the logo, it means they have been verified by an accredited testing lab and they meet the necessary safety standards. Do not remove them while looking at the sun. While Wisconsinites won't witness a full eclipse, you'll still need "eclipse glasses", or some type of other viewer to safely look directly at it. The optical device concentrates the sun's light, which can damage the solar viewer and then your eyes.

Chipps' email came on the heels of Friday's announcement by Dr. Jeff Pape of Authier Miller Pape Eye Care in Norfolk that the eclipse glasses it had distributed might be counterfeit and not safe for people to use during the eclipse.
