 This study investigated the effect of different progressive power lens, PPL, designs on reading performance. It found that a PPL with a wider distance region provided better distance reading performance than a PPL with a wider near area. Additionally, it concluded that the power distribution of PPLs affects user performance at vision-based tasks. Therefore, to provide users with the best visual experience, PPL selection should take into account user needs.
