Changing Lenses: A Unique Perspective in Health and Wellbeing The purpose is to share the Nurses Story. Changing Lenses is based on the narrative of the personal journey of each nurse. These radio interviews allow listeners to hear the human story of nurses, their successes, challenges and how they see the world around them. In this Q and A interview style radio program, the interviewer allows the story to evolve organically. The show is interspersed with the nurses’ favourite pieces of music, poetry or their own writings.
