SleepSmart looks like one of those eye cover thingy-mo-bobs my mom used to wear when she was napping. I never really understood them. I mean, your eyes are closed anyways, so how much light do you really need to block? But this one seems to have a real purpose. SleepSmart is really more like an alarm clock. It monitors your brain waves and wakes you up when you are in the lightest phase of your sleeping pattern. This way when you wake up you feel refreshed and not hung-over. No matter how good a nights sleep you got, a jarring alarm when you are in the thick of a dream is a crap way to start the morning.
