Generally speaking, there is no correlation between 3D vertigo and IQ, and there is no clinical basis for this claim. The balance sensation of human is the result of visual, auditory and haptic senses being transmitted to the central nervous system after comprehensive processing. Patients with 3D vertigo mainly suffer from visual misdirection after being exposed to high frequency and large 3D images for a long time, while the auditory and haptic senses do not feel the relevant information, so the central nervous system becomes uncoordinated and causes vertigo. The factors that affect IQ are usually related to genetics and environment: 1) genetic factors: since human is a combination of both parents’ genes, the genes of both parents play a decisive role in human intelligence; 2) acquired environment: cultural background, family environment, school education and other acquired factors play an important role in shaping human IQ; 3) dietary habits: since human’s brain and nervous system need adequate nutrition during infancy, the development of the brain and nervous system needs to be improved. The development of the brain and nervous system during infancy requires sufficient nutrients as a prerequisite, so it affects the IQ to a certain extent. Therefore, the above explanation shows that there is no connection between 3D vertigo patients and IQ level, but paying attention to children’s intellectual development during infancy, paying attention to the way and method of educating children, and supplementing nutrition can have an impact on their IQ improvement to a certain extent.
