1. Eccentric correction in central visual field loss
Abstract : It is not often that one is instantaneously able to apply the results of basic research. This work is an example of such an exception. A widely held conviction has been that human peripheral vision could not be improved through optical correction. It w. READ MORE

2. Optics for Low Vision Enabling
Abstract : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.

3. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field
Abstract : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. READ MORE

4. Vision Beyond the Fovea: Evaluation and Stimuli Properties
Abstract : This research is about evaluating vision in the periphery. Peripheral vision is of fundamental importance in the performance of our everyday activities. The aim of this thesis is to develop methods suitable for the evaluation of peripheral vision and to assess how different visual functions vary across the visual field. READ MORE

5. Improving Peripheral Vision Through Optical Correction and Stimulus Motion
Abstract : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.
