Optics Tutorial on the Eye
The Online Optics Tutorial “Staying in Focus” introduces students to some of the basic concepts of geometrical optics in the context of the human eye. It combines interactive animations, videos, slides with graphics, and continuous narration that guides the users along in their studies. Focusing mostly on a conceptual approach to the study of lenses and how they form images, this online learning tool is designed for students to work through on their own. They are explicitly encouraged to play with the interactive animations and to perform virtual experiments, thus becoming active learners rather than passive listeners.
