Umm, you should never look at the sun. There are special devices to look at solar eclipses. Actually, If you know its coming ahead of time, you can take a cardboard box, cut a square hole in ithe bottom. Next take a piece of tin foil (bigger than the hole) and flatten the wrinkles out of it with your thumbnail. Then you tape it over the hole in the box and prick it with a straight pin. Finally hold the box at angle with the foil toward the sun, and place a white piece of paper below it. If you did it right, The pin prick will show a circle of light on the white paper, BUT as the eclipse progresses, the circle of light will begin to show progress the eclipse as well without actually looking at the sun.
Remember: Under no circumstance should you look directly at the sun, shaded glasses will NOT protect you.
