There are organizations and professionals throughout the United States and in many other countries that help people with impaired vision to learn to do the things they want and need to do.   You can look on this website to find out how to locate services.  Two of the specialists that are most often involved in helping people with impaired vision are Vision Rehabilitation Therapists (VRTs) and Orientation and Mobility (O&M) Specialists.
