Safety-Certified Solar Eclipse Viewing Glasses Free at LaSalle Library.

Beginning on July 11th, and continuing while supplies last, the Library will offer free Solar Eclipse Viewing Shades that meet ISO certification requirements for viewing the upcoming August 21st Total Solar Eclipse. The “shades” were made possible through a grant from Star-Net, STEM resources for Libraries, with funding from the Gordon and Betty Moore Foundation. The Foundation made this grant available to libraries, both because of the importance of the event, and the importance of eye safety. Regular sunglasses cannot protect eyes from the damaging effects of the sun; only special eclipse glasses that are ISO certified can provide safe viewing.

A solar eclipse is always amazing, but this solar eclipse is particularly special since it is the first time in 99 years that a total solar eclipse will be seen across the width of America, from the west coast to the east coast as it passes through 14 states. It is very important for Illinoisans because it is in Illinois when “totality” – when the Moon will completely block the light from the Sun – will be of the greatest duration; that distinction will be very near Carbondale, at 37.568 degrees North latitude and 89.1029 degrees West longitude.

Partial solar eclipse viewing is also spectacular and can be observed in the LaSalle area at 90.124% obscuration – that is that the Moon blocks out more than 90% of the Sun’s light. Because some of the Sun’s light will be seen, a partial eclipse must be viewed with the special solar eclipse certified glasses, just as a total solar eclipse must be viewed during the time before and after the total eclipse, when the sun is only partially hidden by the Moon.
