Why does sunlight appear to travel in straight lines? How do we perceive the glorious spectrum of colors? It’s all in your head! Learn how the eyes and brain work together to make sense of what we see, and what happens when there’s a kink in the process. You’ll get insight into why some of us are near-sighted or farsighted, and how eye-glasses help correct these conditions.
