Area of Expertise



Barbara Pierscionek completed her first degree in Optometry and PhD in biochemistry and optics at the University of Melbourne. Between the two degrees she undertook extra studies in biochemistry. Subsequent qualifications in management and law were obtained at the Universities of Bradford and Leeds Metropolitan respectively. Professor Pierscionek's research on the optical elements of the eye: the lens and the cornea, has included construction of an instrument which mimics the focussing mechanism of the eye as well as the development of a fibre optic sensor for direct measurement of refractive index in the lens and cornea. Professor Pierscionek has worked at the Universities of Monash and La Trobe in Australia, at The University of Bradford and currently holds a Chair in Optometry and Vision Science at the University of Ulster. Her research has been supported by Research Councils in Australia and UK, British Council and industry grants.

Lecture Title(s)

The Paradox of the Eye Lens
With age we lose the ability to focus on close objects, a process called presbyopia. This is currently not understood because the continual growth of the lens, which leads to an increase in curvature, suggests that the eye should lose ability to focus on distant objects. This paradox is discussed and the explanation given based on results from Professor Pierscionek's laboratory.

Lifestyle and Environmental factors which may affect the optics of the eye. The eye lens governs the fine focussing ability of the eye. This lecture looks at a number of geographical, climatic and lifestyle factors from different populations around the world to see which factors may have an effect on the focussing range of the eye and its rate of change with age.
