    Millions of people suffer from motion sickness (晕动症). They have a lot of activities they fear. They often avoid doing these activities which include long-distance airplane travel, sea-trips, road-trips, even certain movies and video games. However, the French company Boarding Ring promises that it has its way to solve the problem, as long as the users are willing to wear Boarding Glasses!

Why do many people suffer from motion sickness? It is believed that the brain fails to deal with mixed signals from body parts. For example, when you are looking at your phone on a moving bus, your inner ear realizes the move but your eyes, focused on the screen, think you don't move.

Boarding Glasses tries to ease (减轻)motion sickness by making the user's eyes and ears transmit the same message. After the brain receives the same message, it will think you are in a moving environment Though that sounds difficult, the science behind the glasses is surprisingly simple.

The plastic frames (框架)，made up of two round frames on the front and two on the side, are filled with some blue liquid. Any movement can cause the liquid to flow around the eyes. This allows the eyes to sense the move and send the correct signal to the brain.

According to Antoine Jeannin, CEO of Boarding Ring, Boarding Glasses has been tested. The CEO said that over 95 percent of the users felt better after wearing the glasses. The best part is that Boarding Glasses only has a frame, so a single pair can be worn among a group of friends, or even an entire family!
