Dry Eye by the Numbers

100 Million Suffer from Dry Eye Syndrome Due to Natural Aging and Modern Lifestyles  

Dry eye syndrome is one of the most common ophthalmological disorders, causing chronic discomfort in up to 100 million people worldwide, and the disease burden is forecast to increase due to increased screen time and average life expectancy. Risk of dry eye syndrome increases 35% each decade after age 40.

As people grow older the production of oil in the body decreases, which reduces tear production and increases evaporation of tears, resulting in dryness of eyes. A greater risk of acquiring dry eye is also experienced by females, with postmenopausal women being particularly at risk, and again, natural biological changes are the reason for this. Sex hormones are known to play a significant role in ocular surface homeostasis, and studies are investigating how disturbances to this homeostasis may result in dry eye syndrome.

Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye. Consequences of dry eyes range from subtle but constant eye irritation to significant inflammation and even scarring of the front surface of the eye.

In addition to being called dry eye syndrome, dry eye disease, or simply “dry eye,” alternative medical terms used to describe dry eyes include:

  • Keratitis sicca – Generally used to describe dryness and inflammation of the cornea.
  • Keratoconjunctivitis sicca – Describes dry eye that affects the cornea and the conjunctiva. The conjunctiva lines the inside of the eyelids and covers the sclera (the white of the eye).
  • Dysfunctional tear syndrome – Describes the inadequate quality and quantity of tears.
