The second event, a solar eclipse viewing party, will begin at 10 a.m. Monday, Aug. 21, at the Dr. James Carlson Library in south Fargo.
While no data exists for how many made-for-eclipse eyeglasses are in circulation overall, shady distributors of purportedly solar-safe shades abound on the Internet, Fienberg said.
Experiencing a solar eclipse requires care: Looking at the sun during the eclipse - or at any other time - without the proper protective gear can cause eye damage, NASA said.
The public is encouraged to come and learn about the Solar Eclipse that will take place on August 21, and how to view the eclipse safely.
As a measure of excitement surrounding the event, a leading supplier of solar lenses, Arizona-based Thousand Oaks Optical, has sold enough of its filters this year alone to produce roughly 100 million pairs of glasses, company owner Pat Steele-Gaishin told Reuters. Never look directly at the sun without eye protection, even briefly.
The American Astronomical Society has a list of reputable eclipse glasses and handheld viewers on its website - stamped with this approval code: 12312-2. If it is scratched or damaged, throw it away.
Always supervise children using solar filters. Solar view glasses and pinhole cameras also will be available to the public.
If you normally wear eyeglasses, put the eclipse-viewing glasses over them or hold the hand-held solar viewer in front of them.
