VisionApp - Refraction and Presbyopia
NCT07570602 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 16
Last updated 2026-05-06
Summary
Recent Android mobile device technology is available which allows user-measured refractive error and reading add power. This technology could be quite useful to the clinical and research community. The current study aims to evaluate the accuracy, repeatability, and reproducibility of one such technology by VisionApp, specifically with regard to refraction and presbyopia.
VisionApp is an app which runs on a smartphone or other device which uses the distance between the user's face and the phone to determine refractive error, while the user looks at different targets (lines, letters, words, etc).
