French car maker¹ Citroën recently unveiled a pair of glassless, liquid-filled eye-glasses that can reportedly treat the symptoms of motion sickness.

 

法国汽车制造商雪铁龙近日推出了一款没有镜片、镜框装有液体的眼镜，据称能治疗晕车症状。
 

 

Called Seetroën, the ingenious eyeglasses use Boarding Ring technology, which was created by a French start-up of the same name, to treat motion sickness in just a few minutes. According to the official press release, after being worn for 10 to 12 minutes, "the glasses enable the mind to resynchronise with the movement perceived by the inner ear while the eyes were focused on an immobile object such as a smartphone or a book," and the wearer can just take them off and enjoy the rest of the journey.

 

So how do Seetroën cure the annoying condition that has been plaguing mankind for centuries? Well, the secret is literally² in those goofy plastic frames. That blue liquid in the rings around the eyes recreate the horizon line to resolve the conflict between the signals sent to the brain by the eyes and inner ear.

 

Motion sickness occurs when our brain perceives conflicting reports about perceived motion from the eyes and the inner ear. It's usually not a problem when a person is looking out the window because then both organs perceive motion similarly, but when you're looking down at a phone or a book, the eyes don't perceive the motion the same way, and the reports sent to your brain contradict those from the inner ear, and the confusion results in motion sickness.

 

The liquid in the Seetroën rings simulate the angle and movements of the horizon so that the movement detected by the eyes matches that detected by the inner ear; no more conflicting signals, no more motion sickness, apparently³.

 

Since Seetroën glasses are actually glassless, they can be worn by anyone, even over actual eyeglasses. You only need to wear them for 10 to 12 minutes after the symptoms of motion sickness set in, to make them go away.
