What is Low Vision?
There is not a "number" or specific level of vision that determines if someone has low vision. Low Vision Rehabilitation is appropriate as soon as there are specific things that can no longer be done because the vision is no longer good enough.
Low Vision Rehabilitation is the use of optical, non-optical, and electronic vision aids to maximize remaining vision and allow the patient to maintain his or her independence. This process is very goal-specific; the devices prescribed will be customized to your specific needs.
