When you are looking at an object far away, both eyes are pointing directly at the object, and the visual axis of each eye, a line from the fovea to the object of regard, are parallel. If you look at something nearer to you, the eyes must rotate inward so they can both point at the same spot. This is convergence.
When you read, you converge your eyes to look at the print on the page. Then you must move both eyes together, as a unit, across the page to recognize each word or group of words. These eye movements are called saccades, and how well you make them has everything to do with how well you read. Because of conflicts with convergence and focusing caused by over accommodation, a Hyperope has problems with tracking, and will lose their place and skip lines. This is why Hyperopes must wear reading glasses to be comfortable when reading.
