Why do people need to see?

People need to see to navigate and interact with their environment effectively, as vision is a crucial sense for understanding spatial relationships and recognizing objects. Seeing also facilitates communication and social interaction, allowing for the interpretation of non-verbal cues like facial expressions. Additionally, visual input is essential for learning and processing information, shaping our experiences and perceptions of the world. Overall, vision plays a vital role in safety, connection, and cognitive development.
