Your system asks for reduced motion, so this hasn't started. It is nothing but movement, so there is no still version of it to show you instead.
Follow the red ball.
Something to follow.
Follow a moving ball, keep track of two, or spot a number or a different shape. 24 scenes flow into one another, with a different order and pace each time around. Follow the line under the field. The buttons only pause, skip and go fullscreen; there is nothing to answer and no score to chase.
Nothing on this page is timed, scored or saved, and none of it counts toward a streak. It is not an exercise and it is not a claim about your eyes, your vision, or anything else about you. If you want a number, the benchmark is where one comes from.
