In identical experimental situations we tested 22 adults with our proposed Landolt C wall-chart and the so-called TNO Landolt-C chart. Contrary to theoretical expectations, it appeared that there was only a slight difference in the measured visual acuities. Further study will show whether this is an incidental or a structural occurrence.
