Scotoma Mapping Tool

This experimental tool helps you map visual blind spots using dynamic noise.

Instructions

• Use one eye at a time (cover the other)
• Keep your gaze fixed on the center cross
• Click where you perceive distortions, missing or unstable areas
• Maintain a consistent viewing distance

What you may notice

• Central blind spot: missing or altered area near fixation
• Distortions: noise appears warped or unstable
• Faded zones: reduced contrast, blurry gray spots or a flickering sensation. You may see some sparkling stars

You may share the exported file with your eye specialist if needed.
