简要总结
Analyzing the accuracy of mobile-based distant vision charts in clinical practice as an economic alternative for standard vision charts.
详细描述
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.
