Bucky 40 Blinks Zebra Eye Mask Deep sleep or daydreams...anytime, anywhere. 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 cant sleep is too much light-darkness stimulates the natural Melatonin production, which helps you achieve deep, restful, and restorative sleep. Use the 40 Blinks on flights, during short naps, in college dormitories, or for a better quality of sleep at home. Sleep well with comfort and convenient sleep! Traditional sleep masks feel heavy on the eyelids, let ambient light in, and use elastic loops that pull on the ears. The 40 Blinks Sleep Mask 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 night's sleep is guaranteed! Helps with insomnia and other sleep disorders. One of the top 5 things to bring to college. Used to protect lash extensions during sleep. Deep molded cups allow you to blink freely. Adjustable straps to fit any head size Features
