Dry eye disease occurs when your eyes don't produce enough tears or produce tears of poor quality, and while it's rarely serious on its own, it can cause ongoing discomfort and even affect your vision if left unmanaged.
What Causes Dry Eye?
Dry eye can stem from a number of overlapping factors, and identifying the right cause is often the key to effective treatment.
- Aging: Tear production naturally declines with age, making dry eye more common in older adults.
- Environmental Factors: Wind, dry climates, and air conditioning or heating can all speed up tear evaporation.
- Screen Time: Extended screen use reduces how often you blink, which disrupts the tear film over time.
- Underlying Conditions: Autoimmune conditions like Sjögren's syndrome, along with certain medications, can significantly reduce tear production.
- Contact Lens Wear: Long-term contact lens use can affect the tear film and contribute to chronic dryness.
