Pro Reaction Time Reflex Game
Test your visual reaction time in milliseconds (ms). Wait for the red screen to turn green, click as fast as possible, and benchmark your speed against pro gamers.
The Science of Visual Reaction Time & Reflex Speed
How Sight Becomes Action
When light enters your retina, electrical impulses travel through the optic nerve to the visual cortex. From there, your motor cortex signals your finger muscles to contract and click. This entire biological pipeline takes roughly 190 to 250 milliseconds.
Hardware & Latency Impact
Your screen refresh rate makes a measurable difference. A 60Hz screen introduces up to 16.6ms of display delay, while a 144Hz or 240Hz monitor displays the green frame in 4.1ms. Wireless mice can also introduce 8-15ms of latency.
Tips to Shave Off Milliseconds
Physical fitness, good hydration, and 7-8 hours of sleep improve cognitive reaction time by 10-15%. Practice daily sprints on AyFetch to keep your neurological reflexes sharp!
