Morning dry eye symptoms can occur when the eyes are exposed or insufficiently lubricated during sleep. Patients may wake with burning, redness, blurred vision, discomfort, or a sandy sensation.
Possible causes include:
- Eyelids that do not close completely during sleep
- Reduced nighttime tear production
- Dry air from fans, air conditioning, or heating
- Certain prescription or over-the-counter medications
- Eyelid damage or changes following an injury or procedure
- Health conditions that affect the eyes or eyelids
Depending on the cause, treatment may include nighttime lubricating drops or ointment, a moisture-retaining sleep mask, changes to the sleeping environment, or treatment for an underlying eyelid condition. A humidifier may also reduce dryness in the bedroom.
Some antihistamines, decongestants, blood pressure medications, antidepressants, pain relievers, hormones, and other medications can contribute to dry eye. Bring an up-to-date medication and supplement list to your appointment, but do not stop or change any medication without first speaking with the clinician who prescribed it.
