What Is a Convergence Insufficiency?

As the name indicates, it is the inability for the eyes to converge appropriately. What that means is when the eyes engage to fixate at a near point target they don’t come all the way in. This can produce what we know to be called double vision. Blurry vision can also be experienced when you have a convergence insufficiency.

Convergence Insufficiency, The Broad Strokes

Convergence insufficiency cases are probably the most prevalent issue in vision related disorders. They happen to be the most commonly missed ones as well. If a person has otherwise clear vision, this problem may remain undiagnosed. Similarly, most eye exams and school screenings do not look for this and given the implications on academic performance, learning, and development, it’s not something we should ignore or leave unaddressed. As we’ve seen with other medical issues, the pattern shows us that left untreated most conditions worsen instead of righting themselves. A convergence insufficiency disorder can affect us in many areas of life and follow us from childhood to adulthood.

For those of us wondering whether or not we have a convergence insufficiency, don’t fret, we have a list of symptoms for convergence insufficiency’s that might shed some light into what it is we’re looking to address and ultimately treat. The symptoms can range in severity for each item but are not limited to: 

  • Double vision at near point
  • Blurry vision
  • Eye strain
  • Fatigue
  • Eye pain
  • Headaches
  • Light sensitivity

What Causes Convergence Insufficiency?

What Causes Convergence Insufficiency?

Now, the cause for these symptoms are associated with convergence insufficiency but what about the cause of convergence insufficiency in general? Science isn’t able to tell us the origin of convergence insufficiencies yet, but what we can reason is that to some extent it is influenced by genetic factors as well as environmental factors. For now there's no clear cut origin. Aside from the physical symptoms, we can talk about the effect it could have on our daily lives. The ability to converge effectively is paramount when it comes to our quality of life. If we are unable to converge, it can affect everything from learning to personality development. With double or blurred vision, learning for children comes next to impossible depending on severity. For adults, doing near point work will prove difficult. Also, pushing through these difficulties with the exertion of energy will end up being the origin of maladaptive behaviors that are used to evade the discomfort of the issue.

Treatment For Convergence Insufficiency’s

For this particular disorder there happens to be scientific backed research for the therapeutic value of vision therapy. The Convergence Insufficiency Treatment Trial (CITT) published the results from two trials that indicate that vision therapy programs are effective in treating children and adults who have CI. They also released the Convergence Insufficiency Symptoms Survey (CISS) to help in diagnostic measures. What the study concluded was that a regiment of vision therapy and orthoptics resulted in the successful treatment of children and adults who suffered from CI.  At Amplify EyeCare, we utilize this exact approach when it comes to treating out-patients who have a convergence insufficiency. Our vision therapy program uses a well rounded approach to achieve the best results for each person with a tailor made therapy program. With an advanced vision exam and therapy patients can look forward to tackling this issue.

Common Questions

Convergence insufficiency affects the eyes' ability to work cohesively, especially for near tasks. Depth perception, reliant on both eyes working harmoniously, can be compromised when they don't converge effectively. An eye doctor can identify these issues through a functional eye exam. Impaired depth perception can challenge everyday tasks like reading, sports, or even driving.
Excessive screen time can strain the eyes, exacerbating symptoms in those with convergence insufficiency. Extended near work challenges the eyes to converge consistently, potentially intensifying discomfort. Regular breaks and consulting an optometrist can be beneficial.
Yes, convergence insufficiency can hinder academic performance. Students often struggle with reading, comprehension, and maintaining concentration, primarily due to visual discomfort. Vision therapy, guided by an optometrist, can help alleviate these challenges, ensuring smoother academic progress.
Individuals with convergence insufficiency might experience increased discomfort using VR. The disparity between visual input and physical orientation can amplify VR motion sickness. A functional eye exam can pinpoint convergence issues, guiding appropriate interventions.
Convergence insufficiency can manifest as headaches, blurred vision, or double vision. These symptoms might be mistaken for other neurological conditions. It's vital to see an eye doctor to differentiate and ensure accurate diagnosis and treatment.
