The dizziness that occurs when a patient looks at a cell phone can be attributed to the following reasons: 1. The screen is related to visual stimulation, and the patient may have refractive error in both eyes, which is more likely to occur. 2. This is due to strain on the neck muscles, tension in the neck muscles, or compression of the vertebral artery by a herniated intervertebral disc, which can cause a lack of blood supply to the brain and manifest as cervical vertigo, accompanied by stiffness and discomfort in the neck. 3. Consider the relationship with the patient’s balance receptors and dysfunction of the semicircular canal, which can cause dizziness in patients who usually have episodes of dizziness.
