On April 8, 2024, a total solar eclipse is set to pass through Illinois. In preparation for this celestial event, the Illinois Optometric Association (IOA) has shared important safety guidelines for viewing the eclipse.

According to the IOA, individuals should always inspect their solar filter before use, as stated by the organization, "if scratched, punctured, torn, or otherwise damaged, discard it." The association also emphasizes the importance of supervising children while they use solar filters.

For those who wear eyeglasses, the IOA advises, "keep them on. Put your eclipse glasses on over them, or hold your handheld viewer in front of them." Additionally, individuals are reminded to stand still and cover their eyes with eclipse glasses or a solar viewer before looking up at the Sun, and to turn away and remove the filter after viewing the Sun.

It is crucial to avoid looking at the Sun through unfiltered cameras, telescopes, or binoculars, as it can cause serious injury. The IOA recommends seeking expert advice before using a solar filter with any optical device.

In terms of maintenance, the association suggests using a microfiber pouch or a soft, nonabrasive tissue to clean eclipse glasses. It is essential to keep cardboard eclipse glasses dry to prevent damage.

The IOA also highlights the ISO 12312-2 standard for solar filters and recommends using welding filters with a shade number of 13 or 14 for optimal viewing. However, adjustable welding helmets or similar products should not be used to view the Sun as they pose a risk to eyesight.

As the solar eclipse approaches, the IOA reminds everyone to enjoy the event responsibly and prioritize eye safety.
