Divergence excess is best described as a pattern where:

Explanation:
Divergence excess describes an exodeviation that is larger when the patient fixes on a distant target than when they fix on a near target. This happens because at near, the act of focusing causes accommodation, which brings about convergence via the AC/A ratio. When the AC/A ratio is relatively high, this near accommodative convergence is strong enough to reduce the exodeviation at near, making the near angle smaller. At distance, there’s less accommodative convergence, so the exodeviation remains larger. This pattern distinguishes divergence excess from other patterns where near and distance angles are equal or near exodeviation is greater.
