Convergence is the coordinated movement and focus of our two eyes inward on close objects, including phones, tablets, computers, and books. Convergence skills are learned during our early years, and Convergence Insufficiency is a common problem with the development of these skills.
The symptoms of convergence insufficiency can make it difficult for a child to concentrate on extended reading and may overlap with those of ADHD. The recent CITT study showed that 45% of the children with convergence insufficiency reported attention problems. Some signs or symptoms you may notice are:
- How often does your child have difficulty completing assignments at school?
- How often does your child have difficulty completing homework?
- How often does your child avoid or say he/she does not want to do tasks that require reading or close work?
- How often does your child fail to give attention to details or make careless mistakes in schoolwork or homework?
- How often does your child appear inattentive or easily distracted during reading or close work?
- How often do you worry about your child's school performance?
Eye coordination problems like convergence insufficiency generally cannot be improved with eye glasses or surgery. The American Optometric Association and the 2008 Convergence Insufficiency Treatment Trial clearly support the superiority of office-based vision therapy, supplemented by at-home vision therapy, for treatment of convergence insufficiency.
