This course is designed to introduce students to optical principles. The principles integrated include light behavior, reflection and refraction, vergence, objects, and images, thin lenses, simple model eyes, spherical refracting surfaces, thick lens systems, mirrors, ray tracing, and prisms. Physiological optics will focus on principles such as angular magnification, telescopes, apertures and stops, prismatic effects of lenses, diffraction, polarization, interference, electromagnetic waves,
