Vision: The Story of Sister Margaret Coyne tells the remarkable story of  Irish nun Sister Margaret Coyne, who ran an eye clinic near the Ethiopian-Eritrean border for decades, saving the sight of countless thousands - often in the midst of war, conflict and famine.

Produced and presented by her nephew John Higgins, her story is told in her own words and through the eyes of the Ethiopian and Irish people who know and worked with her -  from her sister Sabina Higgins, to the Spanish doctors who stumbled across her clinic and started an international NGO to support her work, to Ethiopian people living in Ireland and those who live there now - as the Tigray region where she lived once again finds itself embroiled in a brutal civil war.

Vision: The Story of Sister Margaret Coyne is edited, presented and produced by John Higgins of As the Crow Flies Productions, with sound mixing by Neil Kavanagh of Coach House Media. With special thanks to Proyecto Vision and The Daughters of Charity. Funded by Coimisiún na Mean with the television licence fee.
