Blurred vision is most commonly associated with tricyclic antidepressants, which block the receptor for the neurotransmitter acetylcholine, causing the eyes to become dry. It usually subsides within a few weeks after treatment is initiated. Steps you can take if you are experiencing blurred vision include:
- Get an eye exam to rule out other causes of blurred vision.
- Use artificial tears during the day and lubricating ointment at bedtime to relieve the dryness.
- Use a humidifier.
- Avoid smoking.
- Talk with your doctor about punctal plugs.
- Talk with your doctor about changing your dose.
- Talk with your doctor about changing your medication.
