The Effect of Video Camera Magnifier Use on Reading
The most common goal for patients with vision loss who present for vision rehabilitation is
to be able to read. The video magnifier (a device which combines a video camera and a screen
to view the print being magnified) is the device which most often allows low-vision
individuals to read successfully for extended periods of time. Previous studies on the
outcomes of vision rehabilitation have not identified which components of the vision
rehabilitation are effective. The hypothesis of this project is that providing a video
camera magnifier, with basic training in operating the device, will allow patients to
enhance both objective reading ability and subjective report of reading competence.
