Welcome to the Kwon Lab for Low Vision and Brain research! Our lab is based in the UAB Department of Ophthalmology and Visual Sciences. Low vision refers to uncorrectable visual impairment that can interfere with activities of daily living such as reading, driving, or recognizing faces and objects. Over 285 million people in the world are visually impaired (WHO, 2011) and the growing aging population is expected to increase this number. Despite significant advances in our understanding of structural and physiological changes associated with eye disorders, little attention has been given to how people with impaired vision see and learn to recognize the world around them.

Our lab is thus driven to understand the nature of visual perception in impaired vision and its brain mechanisms. We are also interested in translating this knowledge into effective assessment methods or rehabilitative techniques to improve the visual function of low vision patients. To address these questions, we use a variety of tools that include psychophysics, brain imaging (fMRI), retinal imaging (OCT, SLO), eye tracking, computational modeling and clinical assessment tools.
