A Glance at Dry Eyes

Dry eye or dry eye syndrome is a condition in which the eyes are not adequately lubricated by tears. The tear ducts either do not make enough tears or they do not work the right way. Because the tears are unstable, the eyes’ surface will become inflamed and damaged.

Dry eyes can put a damper on someone’s day. It can cause problems with daily activities. However, there are ways to help the eyes feel better and keep dry eyes from being a hindrance.

Different Types of Dry Eye

There are two different types of dry eye.

  • Aqueous tear-deficient dry eye: Low tear production
  • Evaporative dry eye: Tears evaporate too quickly

Dry eye syndrome can also be known as:

  • Lacrimal keratoconjunctivitis
  • Keratoconjunctivitis sicca
  • Dysfunctional tear syndrome
  • LASIK-induced neurotrophic epitheliopathy
  • Evaporative tear deficiency or aqueous tear deficiency

Causes of Dry Eye

There is not one specific cause for dry eye. As people age, they make fewer tears. Dry eye affects men and women but is more prevalent in women. This is especially true for post-menopausal women.

Other factors could cause dry eye:

  • Certain diseases:
    • Sjögren’s disease
    • Lupus
    • Thyroid disease
    • Rheumatoid arthritis 
    • Diabetes
  • Being in a climate that is windy, smoky, or very dry
  • Long-time contact lens use
  • Swollen or red eyelids (Blepharitis)
  • Activities that reduce blinking such as reading or looking at a computer for too long
  • Eyelids that turn in (Entropion) or out (Ectropion)
  • Refractive eye surgery like LASIK
  • Certain medications:
    • Beta-blockers (for blood pressure or heart problems)
    • Sleeping pills
    • Heartburn medicines
    • Diuretics (water pills)
    • Allergy medicines
    • Antihistamines (allergy medicines)
    • Anxiety medicines
    • Antidepressants
    • Decongestants

Preventing dry eyes is a key component of keeping the eyes healthy. Trying to avoid the situations where these risk factors would be present, if possible, is beneficial.
