Convergence Excess

Convergence Excess

This occurs when the natural posture of the eyes is closer in than required for near vision tasks. This means the individual, when they look to near vision tasks, has a natural tendency to aim the eyes closer in than the position they are trying to aim at.For example, when someone is reading their eyes should ideally be aimed and focused on the words on the page. In cases of convergence excess, the eyes would actually aim and focus at a point closer in than the page itself. Often individuals with this can be seen to hold themselves closer to the page or object than is usually necessary.The signs and symptoms associated with convergence excess are often related to prolonged, visually-demanding, near centered tasks such as reading. They may include, but are not limited to the following:

  • Headaches
  • Avoidance of or inability to sustain near visual task
  • Double vision
  • Blurred vision
  • Poor posture/abnormal working distance
  • Pain in or around the eye
  • Eye fatigue
  • Dizziness

Without effective management myopia (shortsightedness) can often result in later years, such as in high school.


In children, vision therapy exercises are preferred for a better long-term reduction of convergence excess. The overall goal is to allow the eyes to aim normally and without undue effort. For adults, a combination of vision therapy, prisms, and eyeglass lenses can be very beneficial.
