Design outcomes

Primary

MeasureTime frame
In this study, reading performance is the main outcome, which is examined with the relevant speed and accuracy tests. Timepoint: After ordering and preparing myopia glasses with both types of lenses, the reading performance is evaluated. Method of measurement: Developmental Eye Movement™ Test (DEM™) - MNREAD acuity chart ( Persian version).

Secondary

MeasureTime frame
Saccadic movement. Timepoint: After ordering and making myopia glasses with two types of lenses, saccadic movements are evaluated. Method of measurement: Developmental Eye Movement™ Test (DEM™).
