Design base on Asian features. Unique dual anti-fog function, visor's surface treated with nano anti-fog technique and the respiratory airflow washing the visor continuously for moving fog as well.

In a study in the American Journal of Respiratory and Critical Care Medicine, researchers examined this by comparing airflow in people when they hummed and when they quietly exhaled.

Sleep apnea syndrome is defined as repeated episodes of cessation of airflow with sleep, often defined with a respiratory disturbance incidence (RDI) being greater than 5 or 10.
