Every sleep mask I’ve ever tried has done a poor job of blocking out the light and I’ve therefore stopped even bothering with them while flying. Of course, the fact that they look a little silly is another big reason I don’t use them.
Thankfully, form and function have finally arrived in the world of sleep masks.
The Lights Out Sleep Mask looks a bit like something that belongs on a superhero’s head. The sleek black design is flashy and cool. Just as importantly, it is ergonomically designed to accommodate the bulge of the eyeballs and to allow them to dart around furtively in REM sleep–thus allowing you a much deeper sleep while traveling. Or so the theory goes.
