Designed to relieve facial tension, discomfort from occasional headaches, and post-screen-time eye strain, SmartGoggles deliver three totally soothing sensations: air massage, gentle warmth, and pleasant vibration. Just kick back somewhere comfortable, slip the goggles over your head, and choose the heat and vibration patterns you like best. (There are settings designed for relaxation, sleep, and focus.) You’ll feel the difference by the time you take the goggles off. But for dataheads: A sensor tracks your heart rate throughout each session—you can check your stats on the Therabody app when you’re done.
