Welcome to the Wittich Vision Impairment Research Lab

Our work includes all aspects of low vision research, creating an interdisciplinary environment in which we can answer complex and multi-layered questions that are relevant to the rehabilitation of individuals with visual impairment.

There is a specific focus on the effect of co-morbidities, such as hearing impairment or cognitive impairment. The goal of including multiple impairments in our research is to be able to make our results as generalizable as possible to the life and daily challenges of persons with sensory loss, their care providers, and the service providers that work with them.

This short video (in English) is part of a promotion series for the Center for Interdisciplinary Rehabilitation Research in Greater Montreal (www.crir.ca). It highlights my research lab and its work on the use and usability of low vision devices for persons with visual impairment.

“I should say that there have been other honorable contributions to the field: Southall and Wittich’s (2012) ‘Barriers to Low Vision Rehabilitation: A Qualitative Approach’ should be essential reading for professionals who have been “at it” for years and want a framework for why some of their clients make no progress when others flourish.”
