Optical defects of the eye and their relationship to visual performance. All of us will need ophthalmic correction (spectacles, contact lenses and/or refractive surgery) at some stage in our lives. This research is important to the whole Australian community as it will lead to improved equipment for measuring optics of the eye and their effects on spatial vision, better techniques for measuring vision, and obtaining a better understanding of the contribution of the optics to human vision.

All of us will need ophthalmic correction (spectacles, contact lenses and/or refractive surgery) at some stage in our lives. This research is important to the whole Australian community as it will lead to improved equipment for measuring optics of the eye and their effects on spatial vision, better techniques for measuring vision, and obtaining a better understanding of the contribution of the optics to human vision. It will provide information about how correcting optical defects through customized refractive surgery and how inducing optical defects (eg with progressive addition lenses) affect vision, and will thus guide developments in refractive surgery and spectacle lenses.
