Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
There are numerous applications for assessing VA; however, the number of validated applications is limited. In this study, the investigators aim to evaluate the external validity, intra- and inter-observer reliability, and feasibility of two applications ("Easy Vision" and "Peek Acuity") for testing the visual acuity.
