Want to improve your performance in sports and eSports? Just 3 minutes a day can improve your dynamic vision with simple eye training exercises. Recommended not only for athletes, but also for students, professionals, and anyone concerned about eye fatigue or aging vision. TRAIN YOUR EYES – GAIN THE EDGE Dynamic vision is the key to success. It determines how quickly and smoothly your eyes can follow moving targets — essential in ball sports like baseball, soccer (football), and tennis, in martial arts that require instant reactions, and in eSports where split-second decisions decide victory. Dynamic vision depends on the extraocular muscles that move your eyes. Just like body muscles, they can be strengthened at any age through consistent practice. This app acts as your personal eye trainer, helping you strengthen eye movement, reaction speed, and focus. ◆ Exercises Included • Teleportation – Train your eyes to track suddenly appearing objects • Peripheral Vision – Expand your field of view and peripheral awareness • Zigzag – Eye movement and diagonal tracking (DVA) • Tile – Vertical and horizontal tracking (DVA) • 3D – Kinetic visual acuity training (3D/KVA) • Flash Memory Test – Improve focus, instantaneous vision, and short-term memory • MOT Skills ◀NEW (Pro) – Advanced multi-object tracking to improve focus and reaction speed Speed control is available — from extra-slow for beginners to ultra-fast for experts. ◆ User Voices - “My reaction time in games improved a lot.” – Apex player, Japan - “Perfect warm-up before sports practice.” – MtMan820, USA - “Helps my eyes relax after long hours of screen work.” – Dirkalirk, USA - “So much content for free.

Improving dynamic vision and reaction speed is the skill that separates winners from losers. Use it as a warm-up before matches, for martial arts and ball games, or as an Aim Trainer for FPS games. It’s also helpful for improving focus for those who find it hard to concentrate (including ADHD tendencies). Your personal eye trainer helps you build stronger vision habits – just 3 minutes a day to stay sharp and focused, and ahead.
