Just a reminder that, if you are going to watch the eclipse, you must wear certified eclipse glasses or you will fry your eyes. An eclipse is no more dangerous then the sun on a normal clear day, but people don't stare at the sun on a normal day. They do for an eclipse, though. Eye damage is instant. It is said to be painless, so you won't know that you fried your eyes right away. Don't take chances.
If you have no interest in the eclipse and remember not to look, then you do not need protection.
If you are going to use binoculars or a telescope, the binos or scope must wear a protective filter. You can take your eclipse glasses off to look through a filtered telescope. And you can take them off after the total phase begins, as long as you remember to put them back on before it ends.
