Reading an eye chart mounted or projected on a wall is a standard part of every visit to the optometrist today, but it wasn't always that way. Centuries ago, practitioners struggled to measure vis ...View Article

The way eyes work together and focus can affect a person’s ability to read, process and understand information. Studies show that deficiencies in these areas can lead to a significant handicap in learning. Vision therapy can help overcome these problems–improving the ability to read and learn.
Convergence Insufficiency (CI) is a type of eye coordination problem, characterized by a difficulty or inability to effectively converge or align both eyes together to perform near oriented visual tasks.
CI may occur in children and adults. Symptoms often include difficulty reading and concentrating on reading tasks, avoidance of near work, double vision (overlapping words) while reading, eye strain, headaches and rubbing or closing of one eye when reading.
CI at school
Studies have shown that children with reading or learning problems have a significantly greater risk of having CI. The symptoms of CI can directly impact reading performance as well as attention and concentration. Once treated, reading, attention and other school performance problems often dramatically improve.
CI at work
CI can cause tired eyes and headaches while doing office work and significantly reduce productivity on the job. This occurs especially when the job calls for extended “close-up” visual tasks such as computer work, reading or written reports.
Importance of treating correctly
In 2008 the National Eye Institute released the results of a major multicenter research study designed to look at methods of treatment for Convergence Insufficiency. Based on scientific evidence, the research has proven that office-based vision therapy is the only successful treatment for CI when compared to all other common methods used by doctors to treat this condition.
