Chapter 1: Clinical Overview
Dry eyes can result from various factors that affect the quantity or quality of tears produced, or how tears are distributed over the surface of the eye. Here are some common causes and contributing factors of dry eyes:
Aging, as tear production tends to decrease
Environmental Factors, such as wind, exposure to smoke or air conditioning
Health conditions can affect tear production or the composition of tears, such as autoimmune diseases, diabetes, Thyroid disorders or Vitamin A deficiency
Medications can reduce tear production as a side effect. These may include antihistamines, decongestants, hormone replacement therapy, antidepressants or medications for high blood pressure
Extended Screen Time
Wearing Contact Lenses
Prolonged activities such as reading or driving
Hormonal Changes; related to pregnancy or menopause
Eye Surgery can temporarily affect tear production and contribute to dry eye symptoms.
It's important to note that individual factors and combinations of factors can contribute to dry eyes, and the severity of symptoms can vary widely from person to person.
