Vision Stimulus
Peripheral vision training overlay for your desktop
A lightweight Windows app that displays gentle animated stars across your screen while you work. The overlay is transparent and click-through — it doesn't interfere with your normal computer use.
Based on research suggesting that temporal contrast (flickering stimuli) and peripheral visual stimulation may help support healthy eye development and provide a "stop signal" for excessive eye growth.

The Science
Temporal Contrast
Research has shown that exposure to high temporal frequencies with high contrast can provide a "stop signal" for eye growth. The gentle twinkling of the stars provides this temporal modulation without being distracting.
Peripheral Stimulation
Modern screen work often involves staring at a fixed point with limited peripheral awareness. The floating stars encourage natural eye movements and peripheral engagement — more like being outdoors where our eyes evolved.
Spatial Frequency Diversity
The app displays both sharp-edged stars (high spatial frequency) and soft dots (low spatial frequency), mimicking the rich visual environment found outdoors that may be protective against myopia progression.
Note
This is an experimental tool based on preliminary research, not a medical device. If you have concerns about your eyes, please consult an eye care professional.
