Course Summary

Dr Mark Rosenfield & David Cartwright (13:35)

Dr Mark Rosenfield is a professor of vision sciences at The State University of New York College of Optometry, where his research explores the visual demands made by the use of computers and digital electronics. Here, Mark talks to David Cartwright about how these demands are changing as technology develops, and our dependence on digital devices increases. Originally termed ‘computer vision syndrome’ and more recently, ‘digital eye strain’, Mark and David consider how these symptoms present, and how optometrists can provide guidance to patients. The viewing distance for screens is decreasing with the development of ‘wearable technology’ - most notably Google Glass and Epson smart glasses. Looking to the future of these technological advances, we consider the possible uses, and implications for users, of this type of ‘wearable’ device.
