17 cool gadgets that tease the future

The Dreamlight is a high-tech eye pillow designed to help you get more rest.

The device uses soothing sounds, such as a rainforest, and special lights to improve your rest. The company also claims it can assist with jet lag and offer a "beauty facial."

The product will launch a crowd-funding campaign later this month.

Other tech companies believe tech can promise more hours of sleep, too. Sleep Number showed off its smart bed, which collects hundreds of measurements per second, and the Nokia Sleep device -- which goes under a mattress -- analyzes what's disrupting your slumber.
