About

Analyzing the accuracy of mobile-based distant vision charts in clinical practice as an economic alternative for standard vision charts.

Full description

Accuracy of mobile-based visual acuity testing in clinical practice is still debatable. The aim of this study was to analyze the accuracy of mobile-based distant vision chart in comparison to standard chart projector.

Enrollment: 288 patients
