Does anxiety cause pupils to constrict?
Stimulation of the autonomic nervous system’s sympathetic branch, known for triggering “fight or flight” responses when the body is under stress, induces pupil dilation. Whereas stimulation of the parasympathetic system, known for “rest and digest” functions, causes constriction.

What would cause pinpoint pupils?
Small pupils can be due to bright light, an emotional response, or looking at something far away. There are six health risks that can cause pinpoint pupils, or miosis. These include substance abuse, prescription drugs, environmental toxins, diseases, Horner syndrome, and trauma to the eye or brain.
What does it mean if you have small pupils?
When your pupil shrinks (constricts), it’s called miosis. If your pupils stay small even in dim light, it can be a sign that things in your eye aren’t working the way they should. This is called abnormal miosis, and it can happen in one or both of your eyes.
What should your pupils look like?
Generally, normal pupils range in size from 2.0 to 4.0 millimeters (mm) in bright light, and 4.0 to 8.0 mm in the dark. To some degree, pupil size tends to get smaller with age. If your pupils are significantly larger than these norms, you have dilated pupils.
What drugs cause mydriasis?
Using drugs such as cocaine, ecstasy, hallucinogenics, and crystal methamphetamine can lead to mydriasis. Hallucinogenic drugs, such as LSD, affect the serotonin receptors in the brain, which can lead to dilation. Stimulants such as cocaine increase levels of serotonin and cause similar effects on the eyes.
