Modern people have irregular life, lack of sleep at night and no dark sleep environment during the day due to various reasons, resulting in listlessness and low work efficiency during the day. It is so easy to cause confusion of biological clocks and endocrine disorders for a long time, which seriously affect health. The city is full of various lights and noises at night, which is easy to cause poor sleep at night and requires sleep supplement during the day. Eye masks can provide light free sleeping environment for daytime sleepers.

The choice of eye masks is also particular. The best choice is natural and soft cotton products. The most comfortable one is the eye mask made of super soft flannelette. And the eye mask should be dark to avoid light. Secondly, when wearing the eye mask, it must be tight and breathable. Too loose is easy to slip in sleep, which makes the eyes stimulated by light, and too tight is easy to compress the nerves around the eyes, affecting the blood circulation.
