CAPE CANAVERAL, Fla. — With the total solar eclipse right around the cosmic corner, eye doctors are going into nagging overdrive.They say mom was right: You can damage your eyes staring at the sun, even the slimmest sliver of it.So it's time to rustle up special eclipse eyewear to use Aug. 21, when the U.S. has its first full solar eclipse spanning coast to coast in 99 years."We have an opportunity to experience a spectacular natural phenomenon, and we can enjoy it with some simple protection. But if you don't use that protection, you'll be paying for it for the rest of your life," says Dr. Paul Sternberg, director of the Vanderbilt Eye Institute in Nashville, smack dab in the middle of the total eclipse path.No peeking, for example, without eclipse glasses or other certified filters except during the two minutes or so when the moon completely blots out the sun, called totality. That's the only time it's safe to view the eclipse without protection.
