Refractive errors such as short-sightedness, long-sightedness or presbyopia (age related decline in near vision) are the leading causes of visual impairment in the world. Of these, presbyopia affects almost 100% of the population above 45 years of age. This represents over 40% of all Australians. Although spectacles provide a safe and easy means of correcting refractive errors, they affect quality of life due to distorted vision, discomfort such as head and neck ache and cosmetic effects. The goals of the project are to better understand the visual performance of young and old people who wear glasses and to develop improved spectacle lens designs to provide clear and comfortable vision over a range of distances.

屈光不正，如近视、远视或老花眼（与年龄有关的近视力下降）是世界上视力损害的主要原因。其中，老花眼几乎100%影响45岁以上的人群。这占澳大利亚总人口的40%以上。虽然眼镜提供了一种安全简便的矫正屈光不正的方法，但由于视力扭曲、头颈疼痛等不适以及美容效果，它们会影响生活质量。该项目的目标是更好地了解戴眼镜的年轻人和老年人的视觉表现，并开发改进的眼镜镜片设计，以在一定距离内提供清晰舒适的视力。
