Description

There are about 12 million people who are blind in the United States. They are male and female, of all ages. What they all have in common is that their vision cannot be corrected and their vision makes it more difficult to do major life activities such as driving, etc. This can also be called visual impairment. Blindness is the condition of lacking visual perception due to physiological or neurological factors. Various scales have been developed to describe the extent of vision loss and define blindness. Total blindness is the complete lack of form and visual light.
