About Me:

Biography:

David Pye obtained his Bachelor and Master of Optometry degrees from the University of New South Wales (UNSW) and is a Fellow of the Contact Lens Society of Australia. After graduation he worked in clinical practice, as a Tutor in the then Department of Optometry at UNSW, in research, in contact lens manufacturing and as a clinical supervisor in the Department. In 1983 he became the Clinic Director and Contact Lens Lecturer in the School of Optometry at UNSW and was Clinic Director for over 25 years. He was an optometrist at the Sydney Olympics, has been with the Eye Team to Bourke and been involved in the eyecare of patients with diabetes. He was involved in the establishment of the Centre for Eye Health (CFEH) at UNSW and was Deputy Director from 2009 until 2012 when he retired. He has published 50 papers, articles or book chapters, supervised over 80 final year research projects, co-supervised 6 PhD students, presented at many international and national conferences and is a reviewer for 22 journals. Associate Professor Pye holds a visiting appointment in the School of Optometry and Vision Science at UNSW as an Honorary Associate Professor, and lectures in the VISN1221 and contact lens courses, is a clinic supervisor in the Advanced Contact Lens Clinic in the Optometry Clinic, is the Preceptorship co-ordinator for years 4 and 5 and is the course authority for  OPTM7301 . His current research areas include the measurement of intraocular pressure, corneal biomechanics, keratoconus, corneal topography, contact lenses and ocular imaging.
