Blindness is known as the state of being sightless in both of the eyes. A totally blind person is not able to see anything, even light. The term “blindness” is commonly used to signify low vision or visual impairment in one or both eyes. This means that even with contact lenses, eyeglasses, medicine or even surgery, an individual does not see well. The terms blindness and blind have been modified to contain a large range of visual impairment. A visual impairment is any visual condition that impacts an individual’s ability to successfully complete the activities of everyday life.
