Why are eyes drier at night?

For most people, dry eyes at night also mean you have dry eyes throughout the day. You are maybe experiencing eye pain during the night and having to get up and put eye drops in several times throughout the night, interrupting sleep.  

So why are eyes drier at night?   

Our body metabolism slows down during sleep to ensure complete rest. As a result, blood circulation slows down. Delivery of nutrients and blood to the eyes is compromised.  

Another common reason for nighttime dry eye is the partial opening of the eyelids. They are allowing tears to evaporate, thus causing dry eyes.   

How TheraLife can help

Theralife Eye capsules are an oral dry eye treatment that promotes the delivery of blood and nutrients to the eyes. The potent anti-inflammatory properties help you heal. We recommend four capsules of Theralife Eye right before bedtime.   

TheralIfe products are 100% natural, suitable for vegans. 

Conventional home remedies for nightime dry eyes

Here are some of the most frequently recommended treatment options for patients with nighttime dry eye:

  1. TheraLife Eye capsules – take four right before bedtime. No messy tapes, no ointment. 
  2. Taping the Lids Shut – For those whose eyelids are partially open. Use a small piece of paper tape and tape the upper and lower lids together. The tape helps the eyelids create a seal. Everyone has tape, but for many sleeping with tape on the face isn’t comfortable, and sometimes it comes off. It can also be annoying when a person puts the tape on and then realizes there’s something they need to do before bed or if they need to get up for the bathroom in the middle of the night.
  3. Ointments – Eye doctors prescribe this frequently. Every night before bed, an ointment is applied to help keep the eyes lubricated. It can temporarily blur the patient’s vision. For some, the ointment doesn’t last through the night, and they may still wake with dry eyes.
  4. Hydrating Nighttime Mask – Place a specialty moisture mask over the eyes. The mask seals in moisture to help keep eyes lubricated. It also protects the eyes from the surrounding environment, including air leaks from a CPAP mask.

What causes nighttime dry eye?

There are several causes of nighttime dry eye, including Nocturnal Lagophthalmos, Compromised Lid Seal, Sleep Apnea, Floppy Eye, and Aqueous Deficient Dry Eye.

  1. Nocturnal Lagophthalmos occurs when the eyelid does not close during sleep. It’s easy to see how slightly open eyes can lead to dry eyes just from evaporation. Impartial lid closure can also prevent natural tears from spreading correctly. Diagnosis of this condition is vital since Lagophthalmos patients are also more likely to experience recurrent corneal erosions.
  2. Compromised Lid – Compromised Lid Seal occurs when the upper and lower lids do not create a perfect seal. Perhaps the lower eyelid is a bit thicker than the upper lid and so sticks out farther, similar to a teeth underbite.
  3. Sleep Apnea is a condition in which breathing stops and starts throughout the night. It can lead to nighttime dry eye because:
  4. Sleep apnea leads to a lack of oxygenation of the optic nerve head during sleep. 
  5. CPAP– a standard treatment for sleep apnea is the use of a CPAP (continuous positive airway pressure) mask that covers the nose and mouth. The mask is very effective for treating sleep apnea but often does not create a perfect seal. If the air leaks are near the eyes, then the dry eye is a result.
  6. Floppy Eye Syndrome occurs when there is extensive lid laxity. For some, the eyelids can “flip over” during sleep from rubbing against the pillow. It can lead to tearing film abnormality and dry eyes.
  7. Insufficient Tear – has long been thought to be the leading cause of dry eye. Dry eyes lead to Meibomian Gland Dysfunction (MGD), which is the leading cause of dry eye. Aqueous deficient dry eye is the lack of tear production.

How many people experience nighttime dry eye?

  • Lagophthalmos can be found in anywhere from 4% up to 20% of the population1
  • Compromised Lid Seal is in 79% of all dry eye people (14% of people are dry eye patients)
  • Research suggests that sleep apnea affects 22 million adults in the United States4
  • Aqueous Deficient Dry Eye occurs in Sjögren’s Patients of which there are over 4 million in the United States5

The estimate indicates that between 27 million – 118 million adults in the United States have nighttime dry eye.

Since these conditions can overlap, the answer to how many people have nighttime dry eye is likely somewhere between those two numbers. A surprising number of adults, nighttime is probably the time of day that their eyes need the most help.
