Blind people do not "see" in the traditional sense, as they lack sight. However, they often experience the world through other senses, such as touch, hearing, taste, and smell. Many blind individuals develop heightened sensitivity in these areas, allowing them to perceive their environment in unique ways.
Additionally, some people who are partially sighted may still have limited vision and can detect light, shapes, or movement. For those who have been blind since birth, concepts of vision may be understood through descriptions, metaphors, and the experiences conveyed by others rather than visual images.
In terms of navigating the world, blind individuals often use tools such as canes, guide dogs, and technology designed for accessibility to help them orient themselves and interact with their surroundings. They also rely on spatial awareness and memory to understand and traverse spaces.
