Bucky 40 Blinks Travel Sleep Masks Bucky's famous 40 Blinks Sleep Mask is a landmark in the most comfortable, convenient sleep. With a 99% customer approval rating and hundreds of thousands of sleep masks sold, this is the best sleep mask on the market. Block out light and sleep soundly anywhere life takes you! The main reason people can't sleep is too much light—darkness stimulates the natural Melatonin production, which helps you achieve deep, restful, and restorative sleep. Use your 40 Blinks on flights, during short naps, in college dormitories, or for a better quality of sleep at home. Traditional sleep masks feel heavy on the eyelids, let ambient light in, and use elastic loops that pull on the ears, but The 40 Blinks Sleep Mask is different. This sleep mask that looks like a bra for your eyes is specifically designed with the utmost comfort in mind—the soft, ultralight design blocks light fully and gently hugs the face without pressure using the adjustable Velcro strap that connects at the back of the head. Deep molded cups allow space between the eye and the mask so you can blink freely without pressure. Made with a fabric that is extremely lightweight, breathable, flexible, and durable, a good nights sleep is guaranteed!
