Recommended model: Venex Sleep Mask
 
Founded in 2005, Venex is best known for its Venex Recovery Wear, which claims to be a popular Japanese market for its mineral PHT fibers that emit weak electromagnetic waves to improve sleep.
 
The Venex sleep mask is also made of PHT fiber, and has long occupied the top three popular eye masks on Japanese e-commerce platforms. The top layer of this eye mask is made of a blend of 84% polyester and 16% polyurethane fibers, and the inner padding is made of cotton fibers, so the eye mask has excellent elasticity and is not prone to pressure during long wear. In addition, this eye mask is available in two sizes, which clearly gives the size reference value, coupled with the triangular arc design at the nose wing, which can make the selected eye mask fit the curve of your face to a greater extent, and the black appearance is strong light absorption, and the overall light blocking performance of the eye mask is better.
 
Although there is a great deal of controversy about how weak electromagnetic waves can eliminate fatigue, and scientific research on how to effectively eliminate human fatigue is continuing, it is still a good blackout sleep mask in terms of material selection and design. However, its price is higher, about 200 yuan, and at present, Venex only has a physical store in Shanghai, and the domestic online official sales channel is also developing, so the purchase channel is relatively inconvenient.
