As the efficacy of low vision service provision is facilitated by clients' access to and proper use of low vision devices, the objective of this study was to evaluate an outpatient clinic-based low vision device lending library program and the functional and psychosocial impact that device use had upon clients. Twenty individuals borrowed portable video magnifiers during the study period. Line items from the Revised-Self-Report Assessment of Functional Visual Performance and the Reading Behavior Inventory were analyzed before and after device loan at two months. The Psychosocial Impact of Assistive Devices Scale-10 and a semi-structured interview were also completed at two months. Reported improvements in reading performance and satisfaction levels on the Reading Behavior Inventory were significant (p<.001). The Revised-Self-Report Assessment of Functional Visual Performance indicated improved independence in reading medications, bills and labels. Higher scores in happiness, independence, sense of control and adaptability on the Psychosocial Impact of Assistive Devices Scale-10 indicated device retention at two months. Qualitative themes included improved independence, time needed to acclimate to the device, personal appraisal impacting motivation and challenges specific to low vision. This article provides occupational therapists a model to facilitate access, person-device fit and successful use of low vision devices to promote therapy outcomes.
