Official title
Assessment of the Accuracy and Repeatability of the VisionApp - Ghosting Measurement Protocol
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 ghosting vision. 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).
