Your Destination for Information
If you will be using solar eclipse glasses to view the eclipse on August 21, make sure they are real before you trust your vision with them! Safe solar glasses should have have the ISO 12312-2 standard printed on them as well as the name of a reputable manufacturer. Be warned that there many listings on Amazon for glasses that claim to be made in the USA by American Paper Optics, but are actually Chinese imitations. These knockoffs have the correct ISO rating and American Paper Optics' address on them, but American Paper Optics has confirmed they are fake. Here is an example of what the designs look like on one set of fake glasses popular on Amazon:
The American Astronomical Society has published a list of safe places to purchase solar glasses, including which vendors on Amazon are selling real products:
If you are purchasing American Paper Optics glasses from a source other than their website and want to make sure that the product is real, feel free to email the company and ask about a particular listing. They are very good at responding quickly.
The Harrison County Public Library will be giving away Rainbow Symphony glasses at our library programs as supplies allow:
Wed. Aug. 9, 6:30 pm at Palmyra United Methodist Church
Sat. Aug. 12, 11 am at the Elizabeth Branch Library
Mon. Aug. 14, 6:30 pm at Corydon Presbyterian Church
Tue. Aug. 15, 9 am at Lanesville Elementary School gym
You can also join us at Bicentennial Park in Corydon or any of our library branches on August 21 from 12:30-4 PM for an eclipse viewing party and fun activities.
Please keep in mind that there are other means of viewing the eclipse besides solar glasses. The safest and easiest way to view with children is to make a pinhole projector, such as this one at NASA. All you need is two pieces of stiff paper and, optionally, a bit of tin foil. A pair of paper plates works great for this project.
