Summary
The role of outdoor activity in myopia development. It has recently been found that spending more time outdoors may reduce the risk of developing short sightedness. This project will examine the underlying basis of these associations and improve understanding of environmental factors involved in the cause of short sightedness, an eye problem that is a major cause of vision impairment globally.

Summary
Short-sightedness (myopia) is one of our most common eye problems, affecting approximately 20% of people. It is usually due to the eye becoming too long for its power. While we can correct short-sight with contact lenses, spectacles and more recently refractive surgery, recent evidence shows that the vision of corrected myopes is poorer than that of people who have good distance vision without the need for an optical correction. This reduction is present even when the optical minification of spe ....Short-sightedness (myopia) is one of our most common eye problems, affecting approximately 20% of people. It is usually due to the eye becoming too long for its power. While we can correct short-sight with contact lenses, spectacles and more recently refractive surgery, recent evidence shows that the vision of corrected myopes is poorer than that of people who have good distance vision without the need for an optical correction. This reduction is present even when the optical minification of spectacle lenses is taken into account (the lenses used to correct short-sightedness make objects look smaller). It is possible that the anatomical changes to the eye that occur in short-sightedness are the cause of the reduced vision. Even if the optics can be fully corrected with refractive surgery, as is now being proposed, this may not result in excellent vision. The anatomical changes may occur in different parts of the eye and depending on where they occur the nature of the visual reduction will vary. The location of the retinal changes may also be important in terms of eventual pharmacological treatments for short-sightedness. In addition, the significance of the visual reduction, in terms of its effect on the functioning of short-sighted people, e.g. ability to perform under less than optimal visual conditions such as in the presence of glare or reduced light levels, is not known. We plan to investigate this by identifying the optical and neural contributions to visual performance in short-sighted people.Read moreRead less
Sensory impairments and driving: can older drivers cope with distracters? This research adopts a multi-disciplinary approach to investigate the problems of older drivers, and drivers in general. The research will provide a clear understanding of how visual and auditory distracters impact upon the driving behaviour and safety of individuals with vision and hearing impairment and those experiencing age-related declines in cognitive skills.

This research adopts a multi-disciplinary approach to investigate the problems of older drivers, and drivers in general. The research will provide a clear understanding of how visual and auditory distracters impact upon the driving behaviour and safety of individuals with vision and hearing impairment and those experiencing age-related declines in cognitive skills. The research is highly significant in terms of improving our understanding of how sensory impairment and age-related changes impact upon driving performance, the impact of an increasingly complex driving and in-vehicle environment and will provide tangible benefits for the road safety of the wider community.Read moreRead less
Improving the visibility and safety of pedestrians, roadworkers and cyclists. Pedestrian and cyclist fatalities cost Australia ~$2 billion/year, accounting for a third of road users killed or seriously injured. Late visual recognition by motorists is the main reason these collisions occur. While visibility aids to improve pedestrian and cyclist conspicuity have been advocated, they have had limited success.

Pedestrian and cyclist fatalities cost Australia ~$2 billion/year, accounting for a third of road users killed or seriously injured. Late visual recognition by motorists is the main reason these collisions occur. While visibility aids to improve pedestrian and cyclist conspicuity have been advocated, they have had limited success. We will use innovative driving measurement techniques to advance understanding of pedestrian and cyclist visibility and the effectiveness of different visibility aids for enhancing pedestrians and cyclist recognition. We will develop novel visibility aids to maximise pedestrian and cyclist conspicuity and evidence-based educational programs to improve the safety of vulnerable road users.Read moreRead less
Peripheral aberrations of the human eye. This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery.

This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery. Being able to better measure and correct peripheral aberrations will lead to improved imaging of the eye and thus contribute to improved detection and diagnosis of ophthalmic disease. The study will benefit ophthalmologists, optometrists, and engineers involved in designing visual instruments. This project will provide training in adaptive optics for graduate students not available in any other Australian institution.Read moreRead less

Late recognition of pedestrians and cyclist by drivers is the main reason for these collisions. We have shown that innovative visibility designs which involve strategic placement of reflective markers on the moveable joints can greatly enhance visibility and hence safety of these vulnerable road users. We will extend this research to incorporate evaluation of these visibility solutions in real-world environments and encourage the widespread use of these designs in the real-world through education and policy change.Read moreRead less

Summary
Eye injury is the leading cause of monocular blindness internationally. Vision loss has devastating consequences, both financial and social. My research aims to develop a comprehensive international register for eye injury. Working with key international partners we will conduct a large-scale retrospective review to validate our data collection tool. Our aim is to revise outdated methods of scoring eye injury to better predict outcomes and improve management and treatment of eye injury.
Developing innovative contact lens designs and materials for effective and safe corneal refractive reshaping. Despite the increasing prevalence of refractive errors, there are limited options available for refractive error correction. Current contact lens designs for orthokeratology, a corneal reshaping technique which temporarily reduces refractive error, are effective for correcting only low to moderate myopia (short-sightedness).

Despite the increasing prevalence of refractive errors, there are limited options available for refractive error correction. Current contact lens designs for orthokeratology, a corneal reshaping technique which temporarily reduces refractive error, are effective for correcting only low to moderate myopia (short-sightedness). In this project, we will use innovative lens design approaches that harness the fluid forces generated in the post-lens tear film, and modulation of the corneal tissue response to these pressures, to develop novel contact lens designs in appropriate lens materials for effective and safe corneal reshaping to correct a wide range of refractive errors.Read moreRead less
The future of corneal refractive reshaping: can we control myopia or is the risk of corneal compromise too great? Refinement of corneal reshaping lens designs, optimised for visual outcomes through manipulation of aberrations, will significantly benefit local contact lens manufacturing and export by expanding the existing market base.

Refinement of corneal reshaping lens designs, optimised for visual outcomes through manipulation of aberrations, will significantly benefit local contact lens manufacturing and export by expanding the existing market base. This research will also strategically position Australian lens manufacturing to capitalise on the market for myopia-control contact lenses, particularly in the Asian region. Significant intellectual property will be generated for Australia in terms of enhanced understanding of the role of manipulation of corneal shape in modulating progressive myopia. Outcomes from this project will enhance the international reputation of the UNSW research group, keeping Australian science at the forefront of this area of research.Read moreRead less

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.
