A symbol rockets across the screen — identify it before your eyes even agree they saw it. Each level flies faster, smaller, and shorter. Fighter pilots score frighteningly well on this.

A symbol flies across the screen — identify it from four choices.
How to play
- Press Start — a symbol flies across the area in a flash.
- When it vanishes, four options appear: click the one you saw.
- Correct levels make the flyer faster, smaller, and briefer.
- One wrong answer ends the run.
Frequently asked questions
What is dynamic visual acuity?
It is your ability to read detail on a moving object — the skill that lets a batter track a fastball or a driver read a sign at highway speed. Here a symbol races across the screen and you pick what you saw from four choices.
How fast does it get?
Level 1 gives you a generous 260 milliseconds; each level shaves 18ms and shrinks the symbol. By level 8 the flash is shorter than a blink and most runs end there — twelve or more is elite territory.
How is DVA different from normal eye-chart acuity?
A Snellen chart measures static detail at a fixed distance. DVA measures how well you hold that detail while the target moves — and it typically degrades much faster with age, fatigue, or a few drinks than static acuity does.
Who cares about dynamic visual acuity?
Pilots, athletes (especially in baseball, tennis and motor racing), drivers, and gamers. Studies have linked DVA strongly to on-field performance in ball sports.
Can I improve it?
Yes — tracking drills like this plus the other vision games on the site train the eye-movement control and encoding speed involved. Expect the biggest gains in the first few sessions.
