Visual Reaction Age

Your visual reaction time reflects both eye health and neural processing speed. As eyes age, photoreceptor sensitivity decreases and neural conduction slows. This test isolates visual processing speed to estimate your eye age.

01 /How to Play

Focus on the center of the screen.
When a visual stimulus appears, click or tap as fast as possible.
Complete 10 rounds — your average visual reaction time is your score.
Your reaction time is compared to population norms by age group.
Lower milliseconds = younger visual processing age.

02 /The Science

Visual reaction time integrates retinal processing speed, optic nerve conduction velocity, and primary visual cortex response time. Unlike simple reaction time tests, this protocol uses specific visual stimulus parameters to isolate the visual processing component. Research shows visual RT increases approximately 1ms per year from age 25, accelerating after 60. The test provides an estimate of your visual processing age relative to population norms.

03 /Pro Tips

Fixate on the center of the screen — peripheral detection is slower.
Blink before each trial to refresh your visual field.
Avoid caffeine deficit — visual processing speed is sensitive to arousal state.
Screen refresh rate matters — 60Hz+ displays give most accurate results.
Test in consistent lighting conditions for repeatable results.
