Causes of Dry Eyes at Night

Several factors can contribute to dry eyes, particularly at night, including:

• Reduced Tear Production: Tear production naturally decreases at night, leading to dryness.
• Screen Time Exposure: Prolonged exposure to digital screens can strain the eyes and reduce blinking, leading to dryness before bedtime.
• Sleep Environment: Dry indoor air, ceiling fans, or air conditioning can evaporate moisture from the eyes.
• Medications: Certain medications, including antihistamines, decongestants, and blood pressure drugs, can contribute to dry eyes.
• Contact Lenses: Wearing contact lenses for extended periods can cause dehydration and irritation.
• Underlying Health Conditions: Autoimmune diseases like Sjögren’s syndrome or conditions like blepharitis can lead to chronic dryness.

Symptoms of Nighttime Dry Eyes

• A stinging or burning sensation in the eyes
• Redness and irritation
• Blurred vision or difficulty focusing
• A gritty or scratchy feeling
• Sensitivity to light
• Watery eyes (a response to excessive dryness)

How to Prevent and Treat Dry Eyes at Night

• Use a Humidifier: Adding moisture to the air can help prevent eye dryness while sleeping.
• Apply Artificial Tears: Lubricating eye drops before bedtime can keep eyes hydrated.
• Reduce Screen Time Before Bed: Limiting digital device use at night can help prevent eye strain and dryness.
• Stay Hydrated: Drinking enough water throughout the day supports tear production.
• Adjust Sleep Position: Avoid sleeping directly under fans or air vents.
• Consult an Eye Doctor: If symptoms persist, an eye specialist can recommend prescription treatments or specialized eye drops.
