Targets drift across the field and one of them is ringed. Follow that one. There is nothing to press and nothing to get right.
Paused.
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.
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.
