There is a large selection of devices to help people with low vision. Some are "optical," meaning that they are glass lenses such as magnifying glasses and telescopes. Others are "electronic," meaning they use video and projection type principles to expand and clarify vision. Some are portable while others sit on a desk or table. All of these types of devices are not usually covered by insurance, but some of the simple ones may be available at little or no cost through public and private support institutions. Optical devices, known as magnifying glasses, have limited magnification, are sensitive to lighting conditions and have a small field of view, making them more suitable for lower levels of impairment. Electronic devices have integral lighting, greater magnification and field of view, are capable of greater contrast, and are suitable for lower to significant levels of impairment.
One way to categorize low vision devices is by their ability to enhance your vision through near, intermediate and distance magnification. Sometimes one device is appropriate for all three. Your selection will be based on your needs and goals. If you only want help with reading then near vision devices will be appropriate, but if you want to see the television or a classroom teacher, a whole different product might be required.
