Visual Reaction Time Test
Tap targets the moment they appear. Three difficulty levels.
What this test measures
The time between a visual stimulus appearing on screen and your finger tapping it. The signal travels from the retina to the visual cortex and out to your motor system in a few hundred milliseconds.
Why it matters
Quick visual reactions are essential for safe driving, sport and avoiding hazards. Slower or asymmetric reactions can sometimes hint at fatigue, screen overuse, or rare neurological causes.
Who may benefit
Drivers, athletes, gamers, and anyone curious about their visual reflexes. If your reaction time feels much slower than usual, an exam with Dr. Roxanna Gangi can rule out vision-related causes.
Fast visual reactions matter for driving, sports, and avoiding hazards. This free reaction time game, reviewed by Dr. Roxanna Gangi, Optometrist, gives a quick millisecond score across three difficulty levels. Slower or asymmetric reactions can signal fatigue, uncorrected vision, or the need for a comprehensive eye exam or a driver's licence vision test.
