Numerical modelling of ocular accommodation process
… deterioration of this system known as presbyopia. While the focus of this thesis is primarily on the former, the latter is also investigated. The first aim of this thesis is take advantage of nonlinear finite element method (FEM) and a purpose-made numerical ray-tracing code in order to …

Assessment of Ocular Accommodation in Humans
… eye altering the focus from distance to near. Presbyopia is the loss of accommodative function that occurs with age. There are many techniques used to measure accommodation, however, there is little consensus as to how clinical data should be collected and analysed. The overarching theme of …

Transparent Tissues and Porous Thin Films: A Brillouin Light Scattering Study
… becomes difficult - a condition known as presbyopia. An age related stiffening of lens mechanical properties has been suggested as a cause for the onset of presbyopia. High frequency (GHz) Brillouin light scattering (BLS) experiments were performed on human lenses spanning an age range …

The application of a three-phase methodology to design an accessible photo CD player for older adults with mildly impaired vision
… the accessibility of a RCV for older users with presbyopia. The effectiveness of the three-phase methodology for designing accessible consumer products was supported by results of this study. The identification of access barriers in Phase I led to the selection of cost-effective design solutions …
