Visual Reflex Test

Reflex vs reaction time

Online “reflex tests” usually measure a visual response task. Medical reflex exams test different physiological responses and require clinical interpretation. ReactionMetric keeps those categories separate.

If community collection is enabled, you can contribute a completed five-trial session anonymously. ReactionMetric stores the raw trial times and coarse device context, then recomputes summary statistics server-side.

Why this differs from the reaction test

The standard reaction-time page uses one simple signal. This reflex task adds spatial target detection and distractor rejection, so it measures a different browser task rather than duplicating the same green-screen interaction. For the simpler one-signal protocol, use the Reaction Time Test.

Not a medical reflex test. If you are concerned about abnormal reflexes, weakness, numbness or another neurological symptom, use an appropriate clinical service rather than this browser tool.
