Thus someone can have a normal optokinetic response and yet be cortically blind without conscious visual sensation. The measurement of visible acuity in infants, pre-verbal children and special populations isn’t always achievable with a letter chart. As a simple examination move, one must verify whether visual stimuli can be fixated, centered and used. The maximum angular quality of the human eye is 28 arc seconds or 0.47 arc moments, this gives an angular resolution of 0.008 degrees, and far away of 1 1 km corresponds to 136 mm.

An identical reaction is in the case of chromatic aberrations, where the color fringes around black-and-white objects are inhibited similarly.
