This study's aim is to ascertain whether the amount of saccades during convergence has any relation to a person's preference of progressive additive lenses (PALs). Since patients who are better adapters to PALs have faster vergence dynamics, we presume those who do not adapt well must have an alternative to compensate for their slower vergence system. The goal of this experiment is to compare the eye movements of those who adapt and those who do not adapt when performing a double-step stimulus experiment. Of the presbyopes studied, eight subjects wear PALs daily, while the other seven could not adapt to PALs. Results concluded that presbyopes who could not adapt to PALs have an increased amount of saccades when performing the convergence experiment as compared to that of those who could adapt.
