That's a lunar eclipse.. Next Eclipse: 21 Feb 2008 - Total Lunar Eclipse (Saros 133, umbral mag. 1.111, max. eclipse 03:26 UT total: 03:00:34 UT to 03:51:32 UT) A total lunar eclipse will be visible over the Americas, Europe, Africa, and western Asia. The next solar one that can damage your eyes is.. 1 Aug 2008 - Total Solar Eclipse (Saros 126, umbral mag. 1.039, max. eclipse 10:21 UT total: 09:21:07 UT to 11:21:28 UT) The track -- 237 km wide at maximum -- begins in north Canada, passes near the North Pole, and into northern Russia. It then runs south-east into China. It is visible as a partial eclipse in Britain, though will not be dramatic. The maximum duration is 2 minutes 27 seconds, and the path width at maximum is 237 kilometers. http://www.hermit.org/Eclipse/2008-08-01/ I don't think it's blindness from eclipses you should be worrying about...
to summarize: lunar eclipse--you'll be fine solar eclipse--either used a shielded telescope, shielded video camera, or one of a variety of methods. even a little exposure can damage your retinas and basically age your eyes long before they otherwise would.
