Say goodbye to motion sickness! These glasses can be used in cars, boats, on bikes, during flights, while playing spinning games, and even with video games. Effectively prevent seasickness, car sickness, airsickness, and all other forms of travel sickness. Designed with nose pads to ensure a comfortable and secure fit for all head sizes. Made from safe ABS material, these glasses are durable and resistant to oxidation for long-lasting use. The anti-motion sickness glasses are magnetically fixed, foldable, detachable, small, and ultra-lightweight, making them easy to take with you on any journey. Featuring a lens-free design with liquid-filled frames, these glasses use black technology to combat motion sickness. The liquid level in the frame changes with vehicle movement, creating an artificial horizon in the user's field of vision and resynchronizing the eyes with the balance system. No drugs, no side effects – just a proven, simple, safe, and natural solution. Instructions: If you feel dizzy while traveling by car, plane, or sea, focus on a stationary object like a book or phone and wear these glasses for 10-14 minutes. This will alleviate your discomfort and restore your good mood, with lasting effects. You can also remove them once the dizziness subsides. Includes: 1 pair of anti-motion sickness glasses
