This is especially important during a partial eclipse.
NASA advises that viewers use proper solar viewing equipment designed specifically for eclipses. Ordinary sunglasses—even very dark ones—are not sufficient protection for looking directly at the Sun.
And there’s another detail people sometimes overlook.
A regular camera, telescope or pair of binoculars should not be pointed at the Sun without an appropriate solar filter designed for that optical equipment. The concentrated sunlight can cause serious eye damage.
So the safest approach is simple:
Don’t look directly at the Sun without proper solar protection.
Why does the Moon cover the Sun so perfectly?
This is one of the strangest coincidences in our sky.
The Sun is vastly larger than the Moon, but it’s also vastly farther away.
