Causes of Dry Eye Disease

 

Excessive Computer Usage

 
When working at a computer or using a smartphone or other portable digital device, we tend to blink our eyes less fully and less frequently, which leads to greater tear evaporation and increased risk of dry eye symptoms.

Contact lens wear

 
Though it can be difficult to determine the exact extent that contact lens wear contributes to dry eye problems, dry eye discomfort is a primary reason why people discontinue contact lens wear.

Aging

 
Dry eye syndrome can occur at any age, but it becomes increasingly more common later in life.

Menopause

 
Post-menopausal women are at greater risk of dry eyes than men of the same age.

 

 

 

 

 

Indoor environment

 
Air conditioning, ceiling fans and forced air heating systems all can decrease indoor humidity and/or hasten tear evaporation, causing dry eye symptoms.

Health conditions

 
Certain systemic diseases — such as diabetes, thyroid-associated diseases, lupus, rheumatoid arthritis and Sjogren's syndrome — contribute to dry eye problems.

Medications

 
Many prescription and nonprescription medicines — including antihistamines, antidepressants, certain blood pressure medications and birth control pills — increase the risk of dry eye symptoms.

Eyelid problems

 
Incomplete closure of the eyelids when blinking or sleeping — a condition called lagophthalmos, which can be caused by aging or occur after cosmetic blepharoplasty or other causes — can cause severe dry eyes that can lead to a corneal ulcer if left untreated.
