These Hian glasses work by combating motion sickness via targeting the underlying biological cause of sensory conflict.
Here is the science on how they work:
1. Reconciling the "Sensory Conflict" Motion sickness occurs when your brain receives conflicting information from your senses. For example, if you are reading a book or looking at a phone in a moving car, your eyes tell your brain you are sitting still. However, your inner ear (the vestibular system) senses the actual movement, acceleration, and turns of the vehicle. This mismatch confuses the brain, resulting in nausea, dizziness, and cold sweats.
2. Creating an Artificial Horizon The frames of these glasses feature four circular, hollow rings (two in the front and one on each side) filled with a colored liquid.
The Physics:
1. As the vehicle moves, tilts, or accelerates, gravity keeps the liquid level, forcing it to move inside the tubes. The Visual Cue: This movement creates an artificial horizon right in your field of vision.
2. Engaging Your Peripheral Vision The reason the glasses have rings on the sides is to engage your peripheral vision. Even if your central vision is focused on a stationary object like a book or phone, your peripheral vision catches the sloshing liquid moving in perfect sync with the car or boat. This tricks your brain into seeing the motion that your inner ear is feeling, "re-synchronizing" your senses and causing the nausea to fade.
