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.

For an accurate assessment, request a comprehensive exam with Dr. Roxanna Gangi, your trusted Optometrist in Toronto and York Region.
Take the test
A target appears in a random spot. Tap it as fast as you can — but don't tap before it appears!

Want a real, in-person assessment?
Online tools are a great starting point, but a comprehensive eye exam with Dr. Roxanna Gangi can detect conditions that screen-based tests cannot — including glaucoma, diabetic retinopathy, and early macular changes.
