Attendees will gain valuable insights into how to deal with a range of non-tolerance issues associated with spectacle wear and how to manage them effectively. This session will start with a brief interlude covering the theoretical side of non-tolerance in spectacle wearers, with the main emphasis on the reasons for non-tolerance. This will be followed by an interactive discussion session where learners will be separated into groups, where they will work out the reason for non-tolerance in various scenarios.
