Low vision devices come in many forms. They can be optical, such as lenses, eyeglasses, and telescopes, electronic devices, such as video magnifiers, CCTVs, and digital assistants, or objects adapted for use by those who are unable to see details, such as those things that give audible cues or are labeled in large print.

Video Magnifiers and CCTVs
Video magnifiers and CCTvs vary in size, but are basically a camera, a screen to view what the camera ‘sees’, and a light source. The size will determine its usefulness for various reading tasks. While most video magnifiers are hand-held and portable, most CCTV units requires its own space on a desktop.
Both have some of the same features:
- More than one magnifying level;
- True color mode is seeing the colors on the screen as they appear on the page;
- Inverse mode is the capability to reverse print to white on a black background; and
- Other color modes, such as yellow print on either a blue or black background, or the reverse which would be blue or black print on a yellow background.
Those are the similarities. Here are the differences: Continue reading Electronic Low Vision Aids:
Browse any of the internet sites, like Amazon or Independent Living, Aids and you will see a vast array of devices called ‘low vision aids.’ Low vision aids can be anything from bold lined paper to the desktop CCTV (closed circuit television).
Simplified, the low vision aids can be divided into 3 basic categories:
- Objects modified for use by the visually impaired;
- Optical devices; and
- Electronic technology.
Familiar to us is the term low vision aides. Most commonly this term is associated with high powered eyeglasses and magnifiers. Assistive technology refers to low vision aids, both high tech and low tech. They are devices and products designed to level the playing field for those with visual impairments. With assistive technology, students can keep up with their classmates and move efficiently through the higher levels of education. The working visually impaired can maintain employment with the right assistive technology in place. When we are not working or going to school, assistive technology helps with activities of daily living. It keeps the visually impaired active, engaged, and independent.
