Introduction of a digital near-vision reading test for normal and low vision adults: development and validation.

ABSTRACT:

Background

MNREAD is an advanced near-vision acuity chart that has already been translated and validated in Greek language. Considering that no validated Greek digital near-vision test exists, our primary objective was to develop and validate a digital near-vision reading test based on the fundamental properties of the Greek printed MNREAD (MNREAD-GR).

Methods

This is a prospective, comparative study. A digital near-vision chart was developed (Democritus Digital Acuity Reading Test - DDART) with text size calibration, audio recording for automatic reading timing, as well as automatic calculation of reading acuity (RA), maximum reading speed (MRS), critical print size (CPS) and reading accessibility index (ACC). Normal and low vision subjects participated in the validation pr
