Eye muscles: There are muscles in the eye that allow us to focus on things up close and look at things in a distance. This muscle changes the shape of the pupil as it looks at these various distances. You're describing your ability to do this, called accommodation. I'm not sure about the ability to make your heart race and what that means.
