Sleep Deprivation and Its Impact on Eye Health

Almost anything you know to be unhealthy can contribute to dry eyes.
Can sleep deprivation cause red eyes?
Can lack of sleep cause blurry vision?
Can sleep deprivation lead to vision problems?

Absolutely.
In fact, signs of sleep deprivation in the eyes can be the root cause of eye pain from lack of sleep and eyelid twitching due to sleep deprivation.
Let’s dive into the underlying causes.

10 Causes of Red Eyes from Sleep Deprivation

  1. Drinking alcohol the night before.
  2. Medications like SSRIs (e.g., Zoloft, Detrol, and many others).
  3. Dehydration: You need to drink more water.
  4. Diuretics (medications that increase urination): Such as caffeine, Lasix (furosemide), and others.
  5. Sleep aids: Like Benadryl, which can dehydrate you.
  6. Lagophthalmos: Incomplete eyelid closure, which is more common than you might think.
  7. Sleep apnea: Can cause red eyes due to floppy eyelid syndrome—yes, it's a real and frequently observed condition.
  8. Insomnia: People with sleep deprivation often struggle to fall or stay asleep, which can tax their eyes, leading to red and dry eyes.
  9. Eye allergies: Often misdiagnosed as blurry vision from lack of sleep, but it could be something else. A full eye exam is highly recommended.
  10. Contact lens overwear: Sometimes misdiagnosed as eye pain from lack of sleep.

Eyelid Twitching Due to Sleep Deprivation

Eyelid twitching often occurs without a clear cause.
Although several explanations have been proposed, eyelid twitching is generally benign, so research and drug therapies are limited.
Twitches usually disappear within minutes to a day or more.

Key Point:

Persistent or severe, uncontrollable eyelid squeezing could indicate essential blepharospasm, a potentially debilitating condition where the eyes close involuntarily.

  • This condition can make safe driving difficult.
  • While its cause is unknown, it can often be treated with Botox injections.

Does Sleep Deprivation Directly Cause Dry Eyes?

No.
Sleep deprivation itself may not directly cause dry eyes, but factors such as:

  • Dehydration
  • Sleep deprivation
  • Calcium imbalances

...can exacerbate eye dryness and create the perception that a causal relationship exists between sleep deprivation and dry eyes.
