Here’s what can happen when you view an eclipse incorrectly — and how to avoid that this April

CNN:

A stunning total solar eclipse will be visible to millions of people across Mexico, the United States and Canada on April 8.

Astronomers are encouraging everyone within the path to enjoy this rare sight for the last time until August 2044 — but only if they can do so safely. And sunglasses won’t be enough to protect your eyes for this celestial event.

A total solar eclipse occurs when the moon passes between Earth and the sun, completely blocking the sun’s face.

Those within the path of totality, or locations where the moon’s shadow will completely cover the sun, will see a total solar eclipse. People outside the path of totality will still be able to see a partial solar eclipse, where the moon only blocks part of the sun’s face.

If your location only affords a view of the partial solar eclipse, some of the sun’s powerful light will always be visible. And any glimpse of the sun’s brightness with the naked eye is not only uncomfortable, it’s dangerous.
