Foldable Portable No Lens Anti-motion Sickness Seasick Liquid Glasses Outdoor Travel Tool Product specification: 1. Degree: 0 2. Material: PP 3. Style: full frame 4. Weight: 35g Product principle: The blue liquid in the ring will flow with your bumps in the car. Create an artificial horizontal line on the front and side of your field of view, allowing visual information and cochlear signals to be coordinated. The success rate can be alleviated and 10 minutes. The problem can be solved within. Features: 1. The glasses feature a ring half filled with a colored liquid. The ring surrounds the eyes both along the frontal axis (right left) and sagittal axis (frontback) so that when it oscillates, it tricks the eye into believing it is seeing the horizon. 2. Starting from the observation that motion sickness appears because of the difference in perception between the sense of balance and sight, use the Boarding Ring technology, which boasts a 95 percent efficiency rate after just 10 minutes. 3. The glasses dont have lenses, so anyone can wear them and even wear them outside the regular glasses. Wearing this pair of glasses for 10 to 12 minutes when you start to experience motion sickness, the motion sickness will disappear.
