• Dry eye syndrome is estimated to affect between 5% and 33% of the adult population worldwide. DEWS 2007, McDonald 2016, Puck 2016.
• Prevalence estimates vary depending on the definition of dry eye disease used, the age of the cohort and the country where the study was conducted Prokopich, 2014.
• Dry eye syndrome is more common in people aged 50 years or older, in females and those who have had refractive surgery. Schaumberg, 2003; DEWS, 2007; Lemp, 2008; Schaumberg, 2009; Pucker, 2016.
• The prevalence of dry eye syndrome increases from 7.5% in people aged in their fifties to 15% in their seventies. College of Optometrists, 2015.
• The male-to-female ratio is 2:3. Bron, 2014; College of Optometrists, 2015.
• One population-based cross-sectional study (n = 3,824 women aged 20–87 years) using data from the TwinsUK study found that 9.6% of women had a diagnosis of dry eye disease, and 20.8% had had dry eye symptoms in the preceding 3 months. The largest sizes were found in women with depression, pelvic pain, irritable bowel syndrome or chronic widespread pain syndrome (p<0.0005). Vehof, 2014.
