How do we see things? Does our vision directly represent the things we see? Do colors exist in the physical world, or just in our minds? In this fast-paced one-hour class, we'll use illusions and virtual demonstrations to learn about the processes of vision in our eyes and brains, the ways in which our brain "constructs" what we see, and why our sight isn't always as reliable as we'd like to think it is.

Have you ever wondered what exactly your eye doctor is doing when they test your vision? How do they go from having you look at an eye chart and asking “Which is better, one or two?” to giving you glasses that perfectly correct your vision? In this one-hour virtual course you’ll learn the principles of optics, the physics of light that eye doctors and lens makers use to correct your vision, through interactive online demos. Basic geometry knowledge is required.
