Digital camera reviews of Orion AstroGogglesDigital camera Review: They really work! Summary: 5 Stars
...even under light-polluted skies. Faint star limits are noticeably increased. Head strap could be a little more secure. Other than that, they are highly recommended.
REVISION MARCH 2008: If I could, I would would change my rating perhaps to 4 stars rather than 5. Why the change? Quite frankly, they are overkill. Yes, everything I wrote above is still true, however a better alternative which is about 95% as effective and allow for normal use in other situations.

Unlike the goggles they don't suppress all other colors than red and they are usable even in dim light (in darkness take them off altogether, of course).
Summary of Orion AstroGogglesSpend a half-hour wearing AstroGoggles before using your telescope, then take them off just before peering into the eyepiece. Your eyes will already be dark-adapted! Put on Orion AstroGoggles when you go inside during an observing session to retain your dark-adapted vision while inside under houselights. Air vents eliminate fogging.
