Eccentric Viewing

The orthoptist taught Marcus about eccentric viewing. Marcus learned how to use the best parts of his peripheral vision to look at whatever he wants to see more clearly.

For instance, when Marcus looks directly at his friend Minh, he can't see Minh's face properly. But if Marcus looks down at Minh's shoulder or past his ear, he can usually see his face a bit better. Marcus might be able to make out whether Minh is smiling or frowning, looking at Marcus or looking away.

If Marcus wants to watch television, he looks at the side of the TV set, then he can use his peripheral vision to see the screen better.

When Marcus uses eccentric viewing, some people think he is not paying attention.
