3D vertigo is mainly caused by watching 3D movies for a long time or playing 3D games for too long, excessive fatigue or vestibular dysfunction. It may also be caused by excessive neurosensitivity, or prolonged malnutrition, hypotension, etc., resulting in impaired spatial orientation of the body and motion or positional illusion, similar to the symptoms of motion sickness. The main clinical manifestations are sudden onset of vertigo, accompanied by nausea, vomiting, drop in blood pressure, pallor, or excessive sweating and breathing urgency. Since 3D vertigo is a sudden onset disease with serious symptoms, it should be treated immediately to prevent accidents. Patients with 3D vertigo should not spend too much time watching 3D movies or playing 3D games, and should rest their eyes and look into the distance at the right time. During the game, it is necessary to avoid rapid movement of the viewpoint, rapid turning, rapid braking, sudden backward movement, etc. to give the brain room to react. Usually, you should pay attention to increase nutrition appropriately, exercise and improve resistance.
