Make Sure Your Eclipse Glasses Are Not Fakes

The County in partnership with other public safety agencies purchased roughly 75,000 solar eclipse glasses currently distributed by first responders, cities, Lincoln County and the Lincoln County School District.  These glasses purchased through Rainbow Symphony, a verified brand, have some identifiable graphics. Common on all glasses is the County logo with “thelincolncountyfair.com” on the front/side. These glasses also have the ISO 12312-2 certification number on the inside.

How to Tell If Your Eclipse Glasses or Handheld Solar Viewers Are Safe?

Short Answer (https://eclipse.aas.org/eye-safety/iso-certification)

We used to say that you should look for evidence that they comply with the ISO 12312-2 international safety standard for filters for direct viewing of the Sun. But now the marketplace is being flooded by counterfeit eclipse glasses that are labeled as if they’re ISO-compliant when in fact they are not. So now we suggest that you make sure you get (or got) your eclipse viewers from one of the suppliers listed on our Reputable Vendors of Solar Filters & Viewers page. (Also listed below)

The following telescope and solar-filter companies manufacture and/or sell eclipse glasses (sometimes called eclipse shades) and/or handheld solar viewers that have been verified by an accredited testing laboratory to meet the ISO 12312-2 international safety standard for such products. They are listed in alphabetical order; those with an asterisk (*) are based outside the United States.

Solar Viewer Brands

You shouldn’t be able to see anything through a safe solar filter except the Sun itself or something comparably bright, such as the Sun reflected in a mirror, a sunglint off shiny metal, the hot filament of an unfrosted incandescent light bulb, a bright halogen light bulb, a bright-white LED bulb (including the flashlight on your smartphone), a bare compact fluorescent (CFL) bulb, or an arc-welding torch. All such sources (except perhaps the welding torch) should appear quite dim through a solar viewer. If you can see shaded lamps or other common household light fixtures (not bare bulbs) of more ordinary brightness through your eclipse glasses or handheld viewer, and you’re not sure the product came from a reputable vendor, it’s no good.

Viewing the eclipse safely can be done with means other than glasses. The American Astronomical Society (www.eclipse.aas.org) and NASA (www.eclipse2017.nasa.gov) both have excellent resources for various ways to safely view the eclipse.

Residents and visitors are encouraged to review our Eclipse Information Guide and Eclipse Pages (www.co.lincoln.or.us) for best practices during, before and after the Solar Eclipse on August 21st.

Remember, be ready, be patient, be safe…and enjoy the solar eclipse!
