On April 8, a rare and exciting event will captivate sky-watchers across the Central and Eastern United States: a solar eclipse. This awe-inspiring natural phenomenon occurs when the moon passes between the Earth and the sun, casting a shadow over our planet and momentarily covering part or all of the sun. Below, our Chicago eye care team discusses more about what a solar eclipse is, where you can see it, and how to do so safely.
What is a Solar Eclipse?
A solar eclipse occurs when the moon's orbit aligns precisely enough with the Earth's orbit around the sun to block out its light, partially or totally. Depending on the alignment, you may experience a total, partial, or annular solar eclipse. A total solar eclipse occurs when the moon completely covers the sun, transforming day to night for a number of minutes. An annular eclipse happens when the moon covers the sun's center but leaves a "ring of fire" around the edges. A partial solar eclipse will treat Chicago on April 8, during which the sun will be mostly covered, though not entirely.
Where Will the Solar Eclipse Be Visible on April 8?
The eclipse's path of totality, which completely obscures the sun with the moon, will sweep across parts of North and South America. People in Texas, Indiana, Ohio, Toronto, and other areas will be able to witness it. Observers located in these areas will be treated to the full majesty of the eclipse, experiencing a brief plunge into darkness during the day. Outside of this path, including in Chicago, a partial eclipse will be visible to a broader audience, offering a glimpse of the moon's shadow on the sun.
Viewing the Eclipse Safely
Viewing a solar eclipse is a thrilling experience, but it's crucial to do so safely to prevent eye damage. Here are a few important tips:
Never look directly at the sun without proper eye protection. Ordinary sunglasses, even very dark ones, are insufficient to protect your eyes from harmful solar radiation. Severe burns on your retina can result in potentially permanent vision loss, including blindness.
Use eclipse glasses or a solar viewer. These special-purpose solar filters safely enable the viewing of eclipses. Ensure they comply with the ISO 12312-2 international safety standard and check to make sure they aren’t scratched or damaged before using them to view the eclipse.
