People with low vision are not blind.
True blindness means there is no light perception at all.
More than 13 million people in the US have low vision. People with low vision have some usable sight. A combination of low vision exams with the use of low vision aids can usually help the visually impaired person carry on with most normal day to day activities. A low vision specialist is important to help evaluate what devices will work best, as well as help determine special ways of using the remaining sight with daily living. There are many different low vision devices made today.
