Screen Calibration - We added a way to calibrate the app to your specific screen. This matters more than you might think. * What it does: Once you go through the calibration the app learns the actual physical size of your screen, not just its pixel count. A 27" monitor
A dirty little secret We probably shouldn’t be writing this. But you don't need expensive equipment to train your visual system. Some of the most effective sports vision exercises have been around for decades—and they work because vision is fundamentally about how your brain coordinates your
There's a difference between being able to fuse a stereoscopic image and being able to fuse it under time pressure. If you've been training vergence exercises in Open Gym, you've probably noticed that at comfortable levels, you can pick out the target circle almost
Right now, as you read this sentence, your eyes are jumping from word to word. You don't feel it happening because your brain hides the blur from you. But if someone filmed your eyes in slow motion, they'd see a series of quick hops with brief
Visual skills that separate playmakers from players—and how to develop them Chris Paul throws a no-look bounce pass through three defenders to a cutting teammate for an easy layup. The arena erupts. Commentators call it "incredible court vision." But what does that actually mean? Court vision is
"Keep your eye on the ball." It's the oldest advice in baseball. It's also impossible to follow literally. A 90 mph fastball travels from the pitcher's hand to home plate in about 400 milliseconds. During the last portion of its flight, the
At some point, usually in your mid-40s, you notice it. The ball gets there a little faster than you expected. The print on your phone seems smaller than it used to be. Your reactions feel a half-step slow. Some of this is physical. Muscles, joints, cardiovascular capacity all decline with
Have you been using 3DVisionGym, but wished things worked a different way? Or maybe felt something was off? Well … let me ask you a question in return; have you skipped the settings? I get it. Nobody wants to fiddle with menus when there is training to do. But a few
How your brain coordinates depth perception—and why it matters for sports performance Vergence? Vergence is your brain's ability to coordinate both eyes so they move in opposite directions—toward each other or away from each other—to lock onto objects at different distances. Every time you shift
In Part 1, we covered the visual skills that matter for clay shooting: tracking, peripheral awareness, depth perception, focus flexibility, and reaction time. But what does the science actually show about how elite shooters use their eyes? A series of studies led by Joe Causer and colleagues provides the most
Breaking Clays: The visual skills that up-level scores You stand at station three on a skeet field. The target emerges from the high house at your left, screaming across the sky at nearly 50 mph. Your eyes lock on, track its arc, intuitively feel the lead, and your finger squeezes
Your optometrist says your vision is perfect. You can read the bottom line of the eye chart. 20/20. So why does the ball seem to disappear halfway to the plate? Why can't you pick up that crossing clay target? Why do you struggle tracking a pass in
