Bucky 40 Blinks is a contoured sleep mask for blocking light during sleep, travel, and naps, weighing 0.57 oz and measuring 3.5 in (8.9 cm) tall by 9.5 in (24.1 cm) wide.
Light can make it harder to rest when you are trying to sleep during the day, nap between shifts, or get comfortable on a long journey. Bucky 40 Blinks is made for those situations as well as bedtime and meditation. Its light-blocking design is intended to encourage natural melatonin production and support deeper, longer sleep.
The raised, convex eye sections leave room for natural blinking without friction against the mask. The molded foam follows facial contours, while the mask’s shape is designed to avoid unwanted pressure on the eyes and head. It can also help keep natural or false lashes from twisting and tangling during sleep, and is designed not to smudge makeup.
Yes. The elastic strap has a Velcro closure, so you can adjust how the mask sits on your head; its one-size design is intended for men, women, and children. The mask’s flexible construction folds in half for compact carrying, making it useful for travel, work breaks, and daytime rest.
Hand wash Bucky 40 Blinks in cold water with mild soap, then hang it to dry. The mask uses latex-free molded foam and polyester interlock, with polyurethane foam forming the cushioning. Follow this care method to clean the mask between uses without putting it in a machine wash or dryer.
Bucky 40 Blinks is suited to travelers, people working night shifts or double shifts, and anyone who needs to rest while it is light outside. Its contoured, light-blocking eye sections and adjustable strap make it a portable option for naps, travel, and overnight sleep rather than a standard flat mask that rests directly against the eyelids.
Q: How does Bucky 40 Blinks fit?

Q: How should I wash Bucky 40 Blinks?
