In this paper, we explain the effect of lateral chromatic aberration (LCA) when reading information displayed on the screen and how it leads to misinterpretation of charts and values represented. Although the effect can be observed from natural scenes, we focus on LCA on modern display devices. We inform the readers of the significance of issues to those using corrective lenses, especially the high diopter eyeglasses. First, we explain the basics of LCA. Then, we present a user study to observe the effect on users’ judgment when reading charts on display devices. We also introduce a prototype software-based correction method with promising results. Lastly, we suggest guidelines for information visualization designers to avoid such issues.
