• Study Type: interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Best-corrected visual acuity in near vision for the purpose of taking into account the separation difficulties in amblyopia, with Landoldt rings according to the Haase C test which are side by side as series optotypes (2.6 ').

Secondary Outcome Measures

Name	Time	Method
Best corrected visual acuity in distance vision. The examination of the distance vision was also carried out with Landold rings, which, however, were presented as individual optotypes. Their presentation took place partly in an automated process on the PC, partly with the chart projector, whereby the measured values obtained with the PC and the chart projector are to be regarded as equivalent.
