Visual Reaction Time Test: Red to Green Reflex Test
A visual reaction time test measures how quickly you respond to a visual cue. The classic format is simple: wait for the screen to change, then click, tap, or press a key as soon as possible.
Best use: Visual reaction tests are useful for tracking your own reflex speed over time,
especially when you use the same device and testing setup.
What affects visual reaction time?
Your score can change because of attention, sleep, monitor refresh rate, mouse or keyboard latency, browser performance, and whether you are guessing before the cue appears.
How to compare visual reaction scores
- Use an average across several attempts instead of one lucky click.
- Test on the same screen and input device when tracking progress.
- Do not compare touchscreen scores directly with low-latency mouse scores.
- Reset and retest if you clicked before the cue.
