Apollo 11 Disease Myth: Understanding Dry Eye (Keratoconjunctivitis Sicca)

Debunking the "Apollo 11 Disease" Myth

There is no medical condition called "Apollo 11 disease." This appears to be a misunderstanding or urban legend. The actual condition being referenced is keratoconjunctivitis sicca, commonly known as dry eye syndrome.

What Is Dry Eye Syndrome?

Keratoconjunctivitis sicca occurs when your eyes don't produce enough quality tears to maintain proper lubrication. Tears are essential for eye health, providing moisture, nutrients, and protection against infection.

Common Causes

  • Aging - tear production naturally decreases after age 50
  • Medical conditions - rheumatoid arthritis, Sjögren's syndrome, thyroid disorders, diabetes
  • Medications - antihistamines, decongestants, antidepressants, blood pressure drugs
  • Environmental factors - dry climates, wind, smoke, air conditioning, prolonged screen use
  • Hormonal changes - pregnancy, menopause, birth control pills
  • Eye surgery - LASIK and other refractive procedures (often temporary)

Symptoms to Watch For

  • Stinging, burning, or scratchy sensation
  • Stringy mucus in or around eyes
  • Sensitivity to light
  • Redness and irritation
  • Feeling like something is in your eye
  • Difficulty wearing contact lenses
  • Blurred vision or eye fatigue
  • Paradoxically, watery eyes (reflex tearing)

Treatment Options

Management depends on severity and underlying cause:

  • Artificial tears - over-the-counter lubricating drops (preservative-free for frequent use)
  • Prescription medications - cyclosporine (Restasis), lifitegrast (Xiidra) to increase tear production
  • Punctal plugs - tiny devices inserted to block tear drainage
  • Lifestyle modifications - humidifiers, screen breaks (20-20-20 rule), hydration, omega-3 supplements
  • Treating underlying conditions - addressing autoimmune or hormonal issues

When to See an Eye Doctor

Consult an ophthalmologist or optometrist if symptoms persist despite over-the-counter treatments, or if you experience vision changes, severe pain, or signs of infection.
