Our eyes have an automatic focusing system, which enables us to see objects clearly at any distance. The medical term for this process is called accommodation, also known as eye focusing. Under normal circumstances, children have a large amount of focusing capacity. This allows them to maintain clear sustained focus at reading distance.
However, some children do not have the ability to maintain focus for a long period of time while reading, which can make the child experience print move in and out of focus. Treatment for individuals suffering from focusing problems include reading glasses or bifocal lenses. Improved focusing ability can also be developed with a vision therapy program.
