Sleep eye masks can block external light, eliminate interference, and create a dark environment for us, thereby driving the increase of melatonin in the body, resulting in drowsiness, thereby improving our sleep quality. Poor fit of traditional sleep masks not only affects sleep, but may also squeeze the eyes. Our sleep eye masks use integrated 3D hot pressing technology, three-dimensional design to protect your eyes, conform to the contour, with adjustable buckle straps, free your ears, suitable for all head circumference, elastic and freely adjustable, so that you can sleep well. Introduction to the use scenario: 1. During the lunch break in the office, even if the fluorescent lamp is turned off, people who are sensitive to light will still feel uncomfortable, and a sleep mask is needed at this time. 2. When traveling, we may rest in cars, high-speed trains, and planes, when the light flickers on and off, and an eye patch solves the problem. 3. When you are on an official business trip and the curtains in the hotel are not well shaded. 4. Stay up late and work overtime, when you need to catch up on sleep during the day. 5. When meditating on yoga, it calms you down and becomes more focused.
