A low vision consultation is a specialty exam for those patients who are unable to see clearly using conventional eyeglasses or contact lenses. These patients commonly have a visual impairment that is secondary to an eye disease (for example, macular degeneration or diabetic retinopathy). The focus of the exam is to help the patient improve their vision for the tasks that are important to them such as reading, using the computer, or watching television. This is done through the use of low vision aides and devices. Common low vision devices include hand-held magnifiers, telescopes, and closed circuit television systems.
