is called blindness. Blindness can be caused by a variety of conditions, including eye diseases, injuries, or neurological disorders. People who are blind often rely on other senses, such as touch or hearing, to navigate the world around them. Additionally, they may use tools such as canes or guide dogs to help them move around safely. Blindness can have a significant impact on a person's daily life and may require them to make adaptations to their environment and routines.
