People who are completely blind can use the Braille system to read. They use their sense of touch to feel the bumps on the paper that represent letters and words. People have the same body parts that produce our senses. This makes people the same, no matter what ethnicity, race, or gender they are or what characteristics define them. The eyes give us our sense of sight.
Light enters the eye and forms images.
Then the eye changes these images into signals that tell the brain what you are seeing. We use the sense of sight to tell the differences between size, shape, and color, among others. We see everything in our environment. The ears give us our sense of hearing. Vibrations enter our ears and are changed into signals that are sent to the brain.
