This report describes a device that enhances reading material visibility in partially sighted individuals, suggesting broader applications.
An inexpensive, headborne device is described that provides a bright spot of light on reading material even when the material is brought within 1 or 2 cm of the viewing eye. This aid has been used with great success by one of the authors for about 2 yr. This illuminator, or modifications of it, should prove valuable to other partially sighted people.
