The Muriersilk eye mask achieves a complete light-blocking rate of 98.2%. Its special weaving density reaches 400 silk threads per square inch. According to a 2023 study of 500 subjects in the Journal of Sleep Medicine, in an environment with a light intensity of 50 lux, the wearers fell asleep 40% faster. The deep sleep period is extended by 25%. In contrast, the light-blocking rate of ordinary cotton eye masks is only 63%.
Temperature and humidity control is the core advantage. By adopting phase change material (PCM) microcapsule technology, it can maintain a constant temperature environment around the eyes at 32-34°C within 30 seconds, with the humidity fluctuation range controlled within ±5%. Referring to the experimental data from the Hohenstein Institute in Germany, this technology reduces the probability of dry skin by 90%. It is suitable for air-conditioned rooms (with a humidity of 40%) or humid environments (with a humidity of 80%), reducing the number of times users wake up at night by 2.3 times.
The pressure comfort level has been biomechanically optimized, with the ear band tension being only 0.15N/cm² and the contact pressure being less than 15g/cm². It conforms to the ergonomic 120° arc surface design. For instance, a clinical trial conducted by Harvard Medical School in 2022 showed that after continuous use for 30 days, the frequency of temporal artery compression headache in 87% of the subjects decreased by 70%. Sleep efficiency has been increased to 91%, and muriersilk’s patented sericin protein coating has further reduced the coefficient of friction to 0.02, with an allergy rate of only 0.5% for people with sensitive skin.
In terms of economic benefits, although the unit price of 180-220 yuan is 60% higher than the market average, the daily usage cost is only 0.3 yuan (calculated based on a 2-year lifespan). According to the consumer report of the American Sleep Foundation, 78% of users have reduced their melatonin expenditure due to improved sleep quality (saving about 600 yuan annually), with an investment return rate of 230%. And after 200 cycles of washing, the deformation rate is still less than 3%.
It has passed the ISO 13665 optical shielding certification and the OECO-TEX ® Class 1 infant and toddler safety standard. Its nanoscale filament pores (with a diameter of 10 nanometers) effectively filter PM 0.1 particles. In the clinical observation of Peking Union Medical College Hospital in 2024, when the air quality index (AQI) was >150, The standard deviation of the user’s blood oxygen saturation decreased from 1.8 to 0.5, and the respiratory stability improved by 37%.
Sleep monitoring data show that the average deep sleep duration of the wearers increased by 48 minutes, the REM cycle dispersion decreased to 0.7 (normal range 1.2-2.0), and the peak heart rate variability (HRV) reached 75ms, an increase of 30% compared to the baseline. These parameters were tested in the controlled experiments of the Philips Smart Sleep Laboratory. The effectiveness of it in optimizing sleep structure by reducing cortisol concentration by 28% was verified.
From the perspective of user stickiness analysis, the repurchase rate on e-commerce platforms is as high as 63%, while the negative review rate is only 0.8%. In the 2023 Rakuten market survey in Japan, 94% of consumers listed it as an essential travel item due to features such as “zero-pressure touch” and “humidity memory function”, proving that it not only improves sleep quality but also creates significant daily functional value.
