Two modes: Test mode runs the stations you selected back to back at a fixed difficulty and scores them together, and the complete four-station battery is the one that produces the full Sports Vision Score with a rating. Training mode takes one drill on its own and adjusts the level every five reps — up when you are running at roughly 80% or better, down when you drop to 40% or below — so the drill keeps sitting just past comfortable.
What the stations do: Each station targets a different visual skill used in fast-moving sports, and both modes use the same four drills.
Station 1 – Moving Target (dynamic acuity): A broken ring travels across the arena. One side of the ring has a gap. After it passes, choose the side the gap was on using the four arrow buttons. Higher difficulty makes the ring smaller and faster.
Station 2 – Peripheral Awareness: Keep your eyes on the plus sign at the centre. At some point it briefly turns into an arrow — and at the same instant, a dot flashes somewhere around it. Both disappear together after a fraction of a second. Report both answers: the direction the arrow pointed and where the flash appeared, using the two button pads and then Submit. Because the arrow and the flash appear together for the same brief window, you can only catch both by genuinely holding your gaze at centre — glancing out at the flash means missing the arrow. A trial only counts toward your Peripheral score when both answers are correct. The Centre Check stat on your results shows how often you got the arrow direction right on its own. Higher difficulty pushes the dot further from centre and shortens the flash. Screen size and viewing distance still affect this drill, so compare peripheral sessions run on the same device and window size.
Station 3 – Reaction Speed: Wait for the green target to appear, then click or tap it as fast as you can. Clicking before it appears is a false start: it uses up that attempt and is counted as a miss. A response under 120 ms is faster than a genuine visual reaction, so it is treated as an anticipated guess and also counted as a miss instead of being recorded as a very fast time. Clicking the arena instead of the target counts as a miss, and if you do not respond within 2 seconds the attempt times out as a miss — so a long distraction cannot be banked as a very slow reaction time.
Station 4 – Object Tracking: Several dots appear and some flash gold. Those are your targets. When all the dots turn white they scatter and move, bouncing off each other so they stay separate and visible. When they stop, click the dots you believe were the gold ones, then press Submit Selection — you can change your picks before submitting. Partial credit is given for each correct pick.
Levels: Level 1 to 10 controls ring size and crossing time, how far the peripheral dot sits from centre, target size in the reaction drill, and the number, speed and duration of the tracking dots. Rookie starts at level 2, Athlete at level 5 and Pro at level 8. Levels describe this page's own difficulty scale and nothing beyond it.
Training levels: Your result separates three things. Final Level Played is the level your closing block actually ran at, and it is the headline value saved to history. Highest Played is the best level you reached at any point. Next Session Level is what the final block earned — it can be higher or lower than what you played, and it is never reported as a level you completed. Pressing Train Again starts that drill at the earned level, so progress carries forward; going Back to Start lets you pick a fresh Rookie/Athlete/Pro starting level instead.
Scoring: Moving Target and Tracking are scored on accuracy. Peripheral is scored on trials where both the flash location and the centre arrow direction are correct, and its separate Centre Check stat tracks the arrow direction alone. Reaction is scored from your average time. Because you have to travel to the target and click it, not just react, the scale runs on movement-inclusive times: around 350 ms scores near the top and 1.1 seconds near the bottom. That score is then reduced in proportion to any invalid attempts (false starts, anticipated responses, misses and timeouts). Each station is shown as an adjusted 0–100 score with your raw measurement underneath, and the overall score is the average of those adjusted station scores. The adjustment corrects for how easy each station is to guess — the ring task can be guessed one time in four, the dual peripheral task roughly one time in thirty-two — so the station scores are more comparable to each other than raw percentages would be. It does not claim the four tasks are of equal difficulty, and the rating bands are this page's own scale, not validated performance categories. The overall score is the average of the stations you completed; Centre Check is shown for reference and is not part of that average. Only the All 4 Stations battery produces a full Sports Vision Score with a rating — Vision Only and Speed Only are labelled as subset scores, because a number from two stations is not comparable to one from four. All scores describe your performance on this test only.
Tips:
Note: Screen size, refresh rate, input lag and lighting all affect these scores, and results will differ from a professional sports vision assessment. Use it as practice and as a fun challenge, not as a check on your eyesight.
