Visual reaction time

Visual reaction time refers to the amount of time it takes for your brain and body to respond to a visual stimulus, such as a light or movement. When you see something that requires a response, your eyes process the information, send signals to your brain, which then processes what you saw and sends a command to your muscles to react—like pressing a button or moving your hand. This process involves multiple steps and can be influenced by factors like attention, fatigue, age, and alertness. Fast visual reaction times are important for activities requiring quick responses, such as driving or sports.
