Total Visual Impairment refers to a condition where an individual has no usable vision, meaning they cannot see light or objects. This condition can result from various causes, including genetic disorders, injuries, or diseases affecting the eyes or brain. People with total visual impairment often rely on other senses, such as hearing and touch, to navigate their environment. Individuals with total visual impairment may use assistive technologies and tools, such as braille or screen readers, to access information and communicate. Orientation and mobility training can also help them learn to move safely and independently in different settings. Support from family, friends, and professionals is crucial for enhancing their quality of life.
