15 Feb Part 2 – Common Health Related Causes of Dry Eyes

This second post on Dry Eyes is a continuation of Part 1: Why Do Dry Eyes Occur? Dry eyes can occur in as much as 50% of the population. In Dry Eyes – Part 2, we will discuss the health-related causes of dry eyes.


People over the age of 50 are more likely to experience dry eyes. Meibomian Gland Dysfunction tends to get worse with age, which is the cause of most cases of dry eyes.

Seasonal Allergies

If you suffer from seasonal allergies one of your symptoms may be itchy dry eyes. Read more on this in our Eye Allergies Causes, Symptoms, and Treatments article. Dry eye syndrome can make symptoms of ocular allergies worse.


Women are more likely to develop dry eyes, especially post-menopausal women who experience the condition more so than men of the same age. Changes in hormones during or after pregnancy may also trigger the problem.


There are a number of prescription and non-prescription medications that can cause dry eyes and that you should talk with your doctor or pharmacist about including:

  • Antihistamines
  • Antidepressants
  • Decongestants
  • Hormone Replacement Therapy
  • Anxiety Medication
  • Some Blood Pressure Medication
  • Oral Contraceptives


Certain diseases can affect your body’s ability to make tears and as a result cause dry eye symptoms. These include:

  • Sjogren’s syndrome
  • Rheumatoid arthritis
  • Collagen vascular diseases
  • Lupus
  • Scleroderma
  • Diabetes
  • Thyroid Disorders
  • Vitamin A Deficiency

If left untreated, dry eyes can cause inflammation and potential permanent damage to the surface of your eye. It can also lead to corneal ulcers. Early detection is the best prevention and dry eye symptoms are not always present. That’s why our Markham optometrists perform a dry eye test during your eye exam. We can then determine the best treatment options for your condition.

In our third and final post on we’ll discuss specific environmental and activity based causes for dry eyes.
