Researchers Warn Dry Eyes Are Common, but Often Left Untreated
Over 58% report dry eye symptoms but only 20% in Europe and 17% in the US receive diagnosis, with many delaying care for months or years, experts say.
- On September 15, 2025, researchers revealed that more than half of people in the United States and Europe report symptoms related to dry eye, although a small proportion pursue medical diagnosis or treatment.
- The NESTS study, sponsored by Bausch + Lomb, surveyed more than 7,500 adults across several countries to evaluate the prevalence of dry eye and the adequacy of related healthcare services.
- The study found that dry eye symptoms affected more than half of people surveyed, yet formal diagnosis or treatment was received by only 20% of sufferers in Europe and 17% in the United States.
- Dr. Wozniak emphasized that many people overlook an easy treatment option like eye drops that can greatly alleviate symptoms, yet 60% of those affected delay seeking medical advice for at least four months, with 20% waiting over a year, resulting in extended discomfort and changes to daily habits.
- These findings imply a need to educate the public, support healthcare professionals in diagnosis and treatment matching, and encourage regular eye checks to reduce untreated dry eye complications.
