Convergence insufficiency affects many individuals. As a result of this binocular vision condition, it is difficult to sustain near point activities of daily living. The difficulty lies in the adverse symptoms that one experiences. Common symptoms include double vision, blurry letters/words, headaches, eye strain, skipping small words or repeating lines. These symptoms may also mimic ADD/ADHD.
A child who experiences symptoms such as these, may not articulate these struggles because that is their "norm", making it unnecessary to express concern. Why complain if they assume everyone sees this way.
It is important to note that children and adults who suffer from convergence insufficiency typically have 20/20 vision. 20/20 vision is important, however, a developmental optometrist looks further into how the visual system functions. Binocular vision is a skill that is learned, not something that we are born with.
There is proven treatment for convergence insufficiency; office based neuro-optometric rehabilitation (vision therapy).
If there are concerns with your child or someone you know, it is important to have an evaluation by a developmental optometrist to rule out a binocular vision condition, such as convergence insufficiency. It is crucial to determine whether the visual system is leading or impeding.
