Convergence insufficiency

Convergence insufficiency (CI) is a common eye condition that affects the ability of the eyes to work together. This condition occurs when the eyes are unable to converge or move inward effectively, making it difficult to focus on objects that are close up. This can cause a variety of symptoms, including eye strain, headaches, blurred vision, and difficulty reading.


One of the most common symptoms of CI is the feeling that words are "swimming around" or moving on the page when attempting to read. This can be frustrating and can make reading a challenging task. Other symptoms may include double vision, fatigue, and difficulty concentrating.


CI is typically diagnosed through a comprehensive eye exam by an optometrist or ophthalmologist. During this exam, the doctor will evaluate the patient's ability to focus on close-up objects, track moving objects, and perceive depth. If CI is suspected, the doctor may conduct additional testing to confirm the diagnosis.


Fortunately, there are several treatment options available for CI. One of the most effective treatments is the use of prism glasses lenses. These special lenses can help improve the eyes' ability to converge and reduce the symptoms associated with CI. Prism glasses work by altering the way light enters the eyes, which helps to correct any misalignment of the eyes.


In addition to prism glasses, other treatments for CI may include vision therapy, which involves exercises designed to improve the eyes' ability to work together, and medication in some cases.


If you are experiencing symptoms of CI, it is important to seek treatment from an eye care professional. Ignoring the symptoms can lead to continued eye strain and discomfort, as well as difficulty performing everyday tasks such as reading and driving. With proper treatment, most people with CI are able to manage their symptoms effectively and enjoy improved visual function.
