The human eye is a complex and intricate organ that provides us with the
invaluable sense of sight. Commonly referred to as our windows to the world,
eyes allow us to take in the majority of information we obtain about the environment
around us. In fact, experts agree that the eyes contribute nearly 85 percent of an
individual’s total knowledge. Because we rely on our eyes for nearly every activity
we perform, most individuals value the sense of sight above all others.
