Visual Reaction Test
How quickly can you respond to something you see? A ring lights up in a dark field after a random delay. React the moment it appears to measure your simple visual reaction time in milliseconds.

About this test
A visual reaction test measures simple reaction time: one stimulus, one response. Because there is no decision to make, it reflects how quickly your visual system detects a change and your motor system responds.
This version uses a high-contrast light appearing on a dark background instead of a full-screen colour change. A small, bright target is a slightly different visual task from the classic full-screen test on the homepage, so it's interesting to compare your results on both.
Tips for a fair result
- Sit at a comfortable distance and look at the centre of the ring.
- Close other heavy tabs and apps. Background work can delay frames.
- Use the same device each time if you want to track progress.
