Fast, drug-free motion sickness relief These motion sickness glasses use boarding ring technology, a patented and tested paramedical solution. Motion sickness comes from a sense of conflict between what your eyes can see and what your balance system and your inner ear can feel. Using these glasses, the movement of a boat or vehicle creates an artificial horizon. The four rings of the glasses contain an approved horizon-simulating liquid. Put your glasses on at the first sign of illness, keep them on for 10 or 15 minutes, and then take them off. This cures your nausea on the go. The glasses are lensless, so they can be shared among all family and travel companions.
