Abstract

Charts displayed on mobile devices was verified in comparison to standardized ETDRS charts. Such method of visual acuity assessment is characterized by stabile brightness and contrast. Moreover the ability to dynamically display random optotypes eliminates the problem of memorizing the contents of charts, making measurements more reliable. Our tests showed that the VA measured with mobile device and the VA tested using standardized printed charts are not significantly different. Full Text: PDF ReferencesB.
