This is a question I keep hearing in class. At this NASA website, the experts set the record straight. Can looking at a solar eclipse lead to permanent vision loss? YES. Do not look directly at a solar eclipse! It is safe, however, to look with the naked eye only during the short phase of totality (a total solar eclipse) when the whole moon is blocking the sun. In partial eclipse or any other time, it is very important to use eye protection!!

At this website, Mr. Eclipse explains more about how to protect your eyes.

Even staring at the Sun on a regular day is dangerous. Be careful!

Why does a lunar eclipse make the Moon appear red or orange?
The color of the moon is the color of Earth's shadow! Earth's dusty atmosphere causes its shadow to be sunset red.
The next total lunar eclipse will not be visible until Dec. 2010.
