Eclipse eye safety

It is not safe to look at the sun, even with a camera or sunglasses, and even when 99 percent of the sun is blocked. The only time one can safely look at the sun with our naked eyes is during the phase of totality (when the entire sun is blocked out by the moon).  The sun is an extremely powerful source of energy. Our delicate eyes have a convex lens inside them, and if you look at the sun directly using your eyes and without any protection, you will damage them irreparably. NEVER LOOK DIRECTLY AT THE SUN USING YOUR NAKED EYE.
