Human eye is an organ which reacts to light for several purposes. The human eye allows vision. It is one of the five seances. Your pupil changes it's size depending on the light in the room. The eye is the only thing on a human that don't change from birth. The visual system in the brain is to slow to process information.
I think that the human eye is so cool. It has so any features to it. Every eye looks different with the different shape and color. The fact that something so small can see stuff so big is so interesting to me. Doing research on a human eye is so cool just to learn about all it does. People need to know more about how it works what helps the vision stay better and worse. People at least needs to know the basics of the human eye.
