"On April 8, 2024, a total solar eclipse is set to pass through Illinois! Be sure to get your viewing glasses so you can watch the eclipse without any damage to your eyes."

The International Observatory for Astronomy (IOA) has provided important safety guidelines for viewing the upcoming solar eclipse. According to the IOA, individuals should always inspect their solar filters before use and discard them if damaged. It is crucial to read and follow any instructions provided with the filter. Additionally, it is advised to supervise children while they are using solar filters.

It is recommended that individuals who normally wear eyeglasses keep them on while using eclipse glasses. The guidelines emphasize the importance of standing still and covering one's eyes with the eclipse glasses or solar viewer before looking up at the Sun. It is crucial to turn away and remove the filter after viewing the Sun and not to look at the Sun through unfiltered optical devices.

The IOA highlights the significance of seeking expert advice from an astronomer before using a solar filter with cameras, telescopes, or binoculars. Furthermore, individuals are cautioned against using adjustable or auto-darkening welding helmets to view the Sun, as they may pose a risk to eyesight.

In terms of maintenance, manufacturers often provide microfiber pouches to clean eclipse glasses, and it is important to use soft, nonabrasive materials for cleaning. The guidelines stress the need to keep cardboard eclipse glasses dry to prevent damage.

For optimal viewing, the IOA suggests using welding filters with a shade number of 13 or 14. While these filters may be less common in stores, they can be found online, with safesolarviewing.com being recommended as a reliable source.

As the solar eclipse approaches, it is essential to follow these safety guidelines to enjoy the phenomenon responsibly and protect one's eyesight.
