Summary
The conventional examination of the visual acuity (VA) does not take into account the patient's reading speed. However, the consideration of the speed for the recognition of the VA charts' symbols leads to the more accurate and comprehensive assessment of the visual capacity. Therefore, primary objective of this study is to develop and validate a new parameter for the more comprehensive evaluation of visual capacity: the critical visual acuity (CVA). CVA takes into account the speed of recognition of the symbols of the distance visual charts.
