pharmacybiz on 08 Aug 22Dry eye syndrome is incredibly common and prevalence is increasing globally. Studies show that prevalence rates vary from five to 50 per cent but can be as high as 75 per cent in people over the age of 40, in people who wear contact lenses and those who work with computers. It is more common in women than in men, particularly during and after the menopause. According to a new real-world research commissioned by world experts in eye-care, Rohto, more than eight in ten women (83 per cent) indicate that they suffer from the condition, but only once they have had the symptoms of dry eye syndrome described to them. Without detailed explanation, 56 per cent of people say they have never even heard of dry eye syndrome, showing just how under diagnosed it may be. Causes of dry eye Dry eyes are a clinical cause of eye irritation, fatigue, and discomfort, often causing feelings of itchiness, grittiness, and excess watering. If left untreated, dry eyes can even lead to long-term damage and sight problems. Dry eyes may occur if enough tears aren't produced if poor-quality tears are generated or if the tears evaporate from the surface of the eye too quickly. This leads to poor lubrication of the tear film. In a normal eye, the tear film4- the multilayer moist protective film - covers the cornea and lubricates the eye. However, if the lubricative process is faulty dry spots appear on the surface of the eye and this causes irritation and discomfort. The tear film has several layers: fatty oils, aqueous fluid, and mucus. This combination normally keeps the surface of your eyes lubricated, smooth and clear. But problems with any of these layers can cause dry eyes.
