Claim One:
1. A vision test comprising: a projection surface; at least one non-static rotating animated dynamic optotype image shape for measuring the visual acuity of a subject displayed upon the projection surface, the at least one non-static rotating animated dynamic optotype image shape having an image size, a plurality of image segments with image gaps between the image segments, the image segments having a segment size and a segment color, the image gaps having a gap separation distance; a viewing distance between the at least one non-static rotating animated dynamic optotype image shape and a subject being tested for vision acuity; a rate of rotation of the at least one non-static rotating animated dynamic optotype image shape; a dynamic optotype viewing direction; wherein the visual acuity of a subject is determined by varying at least one of the rate of rotation, the image size, the image segment size, the image gaps, and the image segment color; a left fixation point; a right fixation point; a fixation point separation; a left fixation point viewing direction; and a right fixation point viewing direction; wherein the viewing distance is substantially equal to the viewing distance of a Snellen or Landolt vision test, the at least one non-static animated dynamic optotype image shape includes at least three image segments, with a fixation point separation distance of 26.2 cm, wherein the viewing distance is equal to 75 cm, and the fixation point separation angle is equal to 20 arc degrees.
