[Determination of far vision with DIN 58220 (criterion 6/10): computer vision test with high resolution monitor in comparison with vision charts].

Background: The results of nearly automated computerized determination of visual acuity by PC are compared to those of card measurements. The introduction of a new measuring technique should not change the dimension--visual acuity--itself, therefore there should be no difference between the results of the conventional technique and those of the PC.

Methods: Both methods were tested in a group of subjects (N = 100) with vision between 0.
