Low Vision Devices
Low vision patients can maximize their remaining vision and develop strategies that lead to a more independent lifestyle through the use of low vision aids. The main principles behind low vision devices are to enhance contrast, control glare and magnify objects using various tools.
Most people use multiple low vision aids because each is designed to serve a very specific purpose. It’s not unusual for someone to have five or more vision aids. Low vision aids have been broken into the following categories:
