Is your vision affected by dry eyes? Dry eye disease (DED) is one of the most frequently encountered ocular conditions. In fact, 25% percent of patients who visit eye care practitioners report symptoms of dry eye, making it one of the most common conditions.1 The prevalence of DED is estimated to be 7.4% to 33.7% depending on which study is cited, how the disease is diagnosed, and which population is surveyed.2, 3
Recently the Dry Eye Workshop (DEWS) II report was released by the Tear Film and Ocular Surface Society (TFOS), highlighting the importance of dry eye diagnosis and management.
There are many symptoms associated with dry eye including dryness, itching, burning, foreign body sensation, watery eyes and visual fluctuation. Dry eye may impact daily activities such as reading, night driving, watching TV, working on the computer and contact lens wear.4-6 If you have any of these symptoms or your contact lenses are not comfortable all day long, you may have dry eye. Many people with dry eye have not been diagnosed. Thirty million American adults report symptoms of DED7-8 and about 16 million American adults have been diagnosed with this condition.9
Dry eye symptoms are variable and quite common.
The healthy tear film is a delicate balance composed of mucin, proteins, aqueous and lipid components. In chronic dry eye, the concentrations of certain tear proteins are reduced. Patients with an altered tear film due to dry eye can result in symptoms of discomfort, ocular surface damage and visual disturbances, potentially impacting a range of daily activities.
A prospective multicenter study of 217 dry eye patients titled Progression of Ocular Findings (PROOF), evaluated the natural history of dry eye over 5 years.10 In this study, 57% of dry eye patients considered their vision to be moderate, severe or very severe compared to 10.5% for control subjects.
If you think your eyes may be dry or have any symptoms, schedule an appointment with your doctor of optometry today.
