Effexor (venlafaxine) can cause visual disturbances as a side effect due to its impact on neurotransmitters in the brain, particularly serotonin and norepinephrine. These changes can affect the eyes' ability to focus or lead to sensations like blurred vision or light sensitivity. Additionally, the medication can cause dry eyes or changes in pupil size, which may further contribute to unusual visual experiences. If these symptoms persist, it's important to consult a healthcare professional.
