What your eyes take-in and report to your brain is not necessarily exactly what you have seen. The eye is an important sensory organ allowing for vision but without light, vision is impossible. This session will engage participants in elementary lessons that introduce the physics of color and light and illustrate various aspects of human visual perception. Properties of light will be investigated by mixing the primary light colors (not pigments) and simple tests will be performed to measure peripheral vision and explore depth perception, pupil constriction/dilation, and the blind spot. Do you “see” yourself coming to this session?
