Low vision is not the same as blindness or traditional vision problems that can be corrected with eyeglasses or contact lenses. Low vision is vision that does not allow you do to the things that you need to do. This is different for different people and may include the inability to distinguish colors, the loss of visual activity, blurred, obstructed or spotty vision, and the loss of visual fields, such as “tunnel vision.” It is usually caused by injury or eye diseases such as macular degeneration, diabetic retinopathy and glaucoma, but can be a result of a injury or a hereditary condition.
People with low vision usually retain some usable vision, and although there is no cure for low vision, eye care and vision rehabilitation treatment is available. A complete eye exam by an experienced ophthalmologist is essential for an accurate diagnosis of low vision.
