The Connection Between Sertraline and Blurred Vision

Sertraline is known to affect certain physiological processes in the body, including pupil dilation and tear production. These changes can contribute to blurred vision. Pupil dilation, a common side effect of sertraline, can lead to increased sensitivity to light and difficulty focusing. Additionally, reduced tear production can result in dry eyes, another factor in blurry vision. Understanding these mechanisms can help individuals anticipate and address potential vision issues when taking sertraline.

Pupil Dilation and Its Impact

Sertraline can cause the pupils to dilate, making them larger than usual. While this isn’t inherently harmful, it can lead to increased sensitivity to light. Bright lights, especially at night, may cause glare and discomfort, contributing to blurred vision. Patients should be aware of this effect and take precautions when exposed to intense lighting conditions.

Managing Pupil Dilation:
