In reaction to the vehicle accelerations, this liquid moves around the eyes in the frontal direction (left-right), and in the sagittal direction (front-rear). It creates an artificial horizon in the periphery of the visual field, without disturbing the central vision. The eyes have thus access again to the reality of the movement, the sensory mismatch instantly disappears and motion sickness fades in a few minutes.  Review:  When all of the existing solutions settle for curing only the symptoms of motion sickness, Boarding Glasses targets its real cause, resulting in a superior efficiency of over 94% - 2019 Opinionway Study
