Document Summary
The important role of visual information is reflected in the many visual references we use in our language. When visual information is in conflict with information from another sense, you tend to bias your trust towards your sense of vision-for most people, seeing is truly believing. The eye is primarily an instrument to collect, focus, and senses the light stimulus. However, this is only the beginning as the heavy duty processing occurs in the brain. John was rendered blind an occipital lobe stroke at the age of 30. Although he is now unable to perceive the visual world around him, he struggles to maintain his independence. Light travels as a wave and can vary in two respects: the height of each wave, called the amplitude, and the distance between the peaks of successive waves, called the wavelengths. Variations in amplitude affect the perception of brightness.
