Dry Eye Disease (DED) is an eye condition in which the eye either does not produce enough tears or the tears produced are of poor quality. It is a very uncomfortable condition that affects more than 60% of the population over the age of 45, and most people don’t even know they suffer from it.
The Ocular Surface Disease Index (OSDI) test was developed to determine the severity and classify the type of dry eye based on symptoms. By answering the questionnaire, it is possible to find out whether you suffer from dry eyes and which type of treatment is best suited for you.
