Demographics of Dry Eye

Here is what the experts are saying.


From Tearscience Inc. press release 2010:

“Dry eye syndrome impacts 100 million people worldwide, of which greater than 70 per cent suffer from evaporative dry eye.  Treatments for dry eye present a global market of over $2 billion in sales with an annual growth exceeding 10 per cent (due to ageing population).  Dry eye experts believe that an effective treatment needs to address deficiencies of the protective oily lipid layer of the natural tears.”


From Kelly Nichols, OD, MPH, Ph.D, states in Review of Optometry August 2010:

“A recent survey suggested that optometrists see blepharitis (meibomian gland dysfunction) in clinical practice in 47% of their patients.  Ophthalmologists responding to the same survey reported 37%. This is consistent with a study performed in which 38.9% of randomly-selected, apparently normal patients presenting for routine vision examinations had absent or cloudy meibomian gland secretion upon expression.  Dry eye disease alone affects approximately three million women and two million men over 50 in the U.S.  Depending on which study is cited, dry eye affects anywhere from 14% to 33% of the world’s population”.


From Allergan Pharmaceuticals Access states:

“Dry eye disease is one of the most common conditions seen by ophthalmologists, accounting for 15 to 30 per cent of all patient office visits. Many clinically based studies show the prevalence of dry eye disease is extremely high.  And, if population-based dry eye studies are limited to certain age groups, the incidence of the disease is even higher.  A recent Gallup study projected that 77 million adult Americans suffer from dry eye on a regular or occasional basis, including almost 21 million who frequently suffer from dry eye.  While those figures may be on the high side, more scientific studies do estimate that seven to ten million Americans have some form of dry eye disease. Primarily, dry eye strikes mostly the middle-aged and older population groupings”….


From Optometric Management February 2010:

“The National Eye Institute estimates that 15% of Americans have dry eye symptoms, and we expect those numbers to grow as our population ages.  Baby Boomers will begin reaching Medicare age next year, (2011) and roughly 40 million of them are peri- or postmenopausal woman, the group with the highest incidence of dry eye.”
